If your application supports multiple document types and you want to have a distinct help topic for each, then use the help context i.d. generated by running the MAKEHELP.BAT file produced by AppWizard.  Alternatively, run MAKEHM as follows:

makehm IDR_HIDR_,0x2000 resource.h

If the IDR_ symbol for one of your document types is, for example, IDR_CHARTTYPE, then the help context i.d. generated by MAKEHM will be HIDR_CHARTTYPE.

Note, AppWizard defines the HIDR_DOC1TYPE help context i.d. used by this help topic for the first document type supported by your application.  AppWizard produces an alias in the .HPJ file for your application, mapping HIDR_DOC1TYPE to the HIDR_ produced by MAKEHM for that document type. >>

Import Source Points

Lets you import uninterpolated sparsely distributed data from an ASCII sample-points file, thereby creating a new sample-points dataset.  The new dataset is in the same X,Y,Z,A1,...A15 format that Convert Sparse Data to Volume Data  requires.

Once the points are imported, create a source points graphic display using Create Source Points. You can create a color table and manipulate the source point display like other displays.  This lets you view the sparsely sampled data in its original location within the dataset volume.

Creates a new dataset when you import a 2-D grid from a Voxel Analyst-compatible ASCII Data Format (ADF) file into Voxel Analyst.  This lets you import the geometry, data attributes, or horizons in 2-D ASCII-grid files that were output from other software.

To ensure proper orientation of the data, the input ADF file must contain the following keywords and information (parameters are shown in angle brackets (<   >); default parameters are shown in square brackets ([  ])):

•	ATTRIBUTE MGVA_INDEX <0,1,[2]>  ---  indicates the parametric index along which the data is listed:  0 = I, 1 = J, 2 = K.

•	ATTRIBUTE MGVA_MAJOR <row, [column]>  ---  indicates the organization of the data within each layer.  By row, the data is interpreted as row by row; by column, the data is interpreted as column by column.

•	ATTRIBUTE MGVA_TYPE <[GRID]>  ---  indicates the type of data (gridded) to be loaded.

•	ATTRIBUTE <data field> [units]  ---  lists the data fields and default units.

•	POINT FORMAT statement  ---  indicates the order of the information.  If no geographic location is given, the default origin is (0,0,0).  For every subsequent line of data, the origin is incremented by 1.

Import Geometry from Grids

Lets you build an unattributed 3-D volume dataset geometry (that is, a dataset that contains only X, Y, and Z values) from grid files.  A grid can represent an absolute elevation, or it can represent a delta or difference from a reference layer.  You have the option to define by key-in a constant elevation for a layer that is specified.  The key-in value can also be either absolute or a delta from a reference layer.

The X and Y values of a layer are based on X,Y values of the specified grid or on the X,Y values of a previous layer.  The Z values of a layer can be based on the Z values of the selected grid, or they can all be defined as a single value by you.  The Z values can be interpreted as values, or they can be interpreted based on the difference (delta) between the previous layer and the current layer.

Import Geometry from Grids is useful for building geometries for data fields that are represented by a set of grid files, such as MGE Terrain Modeler (MGM) grid files.  Once the geometry is built, you populate it with attributes by using one of the following methods:

•	Use Import Attributes from Grids.

•	Use Import Horizons from Grids (for geologic data).

•	Save the geometry as a new HDF file by using Save As HDF, and then use Convert Sparse Data to Volume Data (for source-point data).

Lets you create a new dataset by resampling the active dataset using a method that may thin or densify the data.  During resampling, the dataset is checked for void values.  When processing is complete, the new dataset becomes the active dataset loaded in memory.  You need to save the dataset on disk when resampling is complete.

Resample Dataset Dialog Box


Resample Dataset Dialog Box

Use this dialog box to select the dataset to be resampled, to type a name for the new dataset, and to select a resampling method.

Input:

    Dataset  ---  displays the active dataset name.  You can select a different dataset from the drop-down list.

    Number of Indices  ---  displays the IJK dimensions (parametric range limits) of the active dataset.

Output:

    Resampled Dataset  ---  displays a default name for the new dataset.  You can type a different name.

Resample Method:

    Keep every nth entry  ---  uses every nth entry along the grid column/row for the corresponding column/row entry in the volume.  All intermediate grid values are discarded.  The resulting volume dimension is equal to the largest integer value greater than or equal to (grid dimension)/n.

    Replace every n with average  ---  computes the average for every n entries along the grid column/row, and uses the result for the corresponding column/row entry in the volume.  The resulting volume dimension is equal to (grid dimension)/n.

    Add n entries between indices  ---  adds n entries between each IJK parametric index along the grid column/row.  The resulting volume dimension is increased by (grid dimension - 1) * n.

    Interpolate into n indices check box  ---  linearly interpolates the entries along each grid row/column into n entries and uses the results to define the corresponding volume entry.  This check box can be used to densify or to thin the dataset.  The resulting volume row/column dimension is equal to n.

    Where n equals  ---  resamples along the I, J, and/or K parametric axes.  Type the value(s) to be used for the selected resampling method.


Define Grid

Lets you define a uniform, regular, or irregular 3-D grid for a selected dataset using interactive graphics to add grid slices to any or all of the dataset's IJK parametric axes.  You also can copy the geometry of an existing grid or modify an existing grid's geometry (including structured grids).  To modify an existing grid, you can densify it (add new slices to it) and/or thin it (delete existing slices from it).

See the Glossary in the Voxel Analyst User's Guide for definitions of uniform, regular, irregular, and structured grids.

NOTE    When you modify an existing grid's geometry, any data fields associated with it are lost.

When defining a new grid or geometry, an empty (unattributed) dataset is created (and it becomes the active dataset).  The new dataset can be modified and populated by using one of the following methods:

•	Use Import Datafields from Grids.

•	Use Import Horizons from Grids (for geologic data).

•	Save the geometry as a new HDF file by using Save As HDF, and then use Convert Sparse Data to Volume Data (for source-point data).

If you are working with sparse (sample) data points, the saved HDF file can optionally be input into Convert Sparse Data to Volume Data as the control geometry or as the minimum bounding volume (MBV).

Define Grid Dialog Box

Use this dialog box to select an existing dataset (or to type a new dataset name), to define the grid size, to add one or more grid slices, and to delete one or more grid slices.  (Defaults are provided for a new dataset name and grid size.)

Dataset  ---  displays a default dataset name.  You can type a different name or select an existing dataset name from the drop-down list.

NOTE    If you type an existing dataset name, a confirmation dialog box appears.  Click Yes to modify the existing dataset (any data fields associated with the grid are lost); click No to copy the existing dataset (without its associated data fields) to a new dataset.  Click Cancel to default to the active dataset.

Grid Size (IJK):

    These text boxes display IJK parameter values for the grid size.  (By default, the size is 2x2x2.)  You can change the grid size to the required resolution by typing new IJK values in the text boxes.

NOTE    If you want to change the grid size, you must do so before adding/deleting grid slices.

NOTE    The default minimum bounding volume (MBV) for the new dataset is the MBV of the active dataset.  If no dataset is loaded, the MBV is arbitrary.

Slice Operations:

    IJK  ---  select the parametric axis for which you want to add/delete grid slice(s).  (By default, the I axis is selected.  This corresponds to adding horizontal slices that are perpendicular to the Z axis.)

    Add Single  ---  lets you add a single grid slice.

    Add Multiple  ---  lets you add multiple grid slices.  Type the number of slices in the Number of Slices text box.

    Number of Slices  ---  type the number of slices to be added to the grid.  (By default, the number of slices is 2.) (This text box is disabled when adding/deleting single slices or when deleting multiple slices.)

    Delete Single  ---  lets you delete a single slice.

    Delete Multiple  ---  lets you delete multiple grid slices.

Display All Surfaces  ---  displays all grid slices (surfaces); otherwise, only the surfaces perpendicular to the active axis are displayed.

Undo  ---  undoes each addition/deletion in reverse order beginning with the last addition/deletion.


Edit Attributes

Lets you edit values in a selected data field of a 3-D grid.  Optionally, you can construct a local geometry (cube) or area of influence centered around the edited data point (within the dataset's parametric space) and reinterpolate the data within the cube.  This lets you visualize connected data such as contaminant plumes.  It also lets you edit out bad data and to volume digitize/interpret new data into the model.

Edit Attributes reinterpolates data field values on all grid nodes in the cube.  The grid nodes immediately next to the cube and the center node are used as input points for the reinterpolation, or the edges can be used for faster interpolation. Constant interpolation applies the value of the center node to all nodes within the influence range.

NOTE    The active dataset must be gridded data.  To see immediate visual results, you must have created at least one graphic display.  It is also recommended that you create a color table using Create Color Table.

Edit Attributes Dialog Box

Use this dialog box to select the dataset for which you want to edit attributes, to modify the center node, to define the cube or influence range for the interpolation, to select a data field for the interpolation, to select an interpolation method, to modify the attribute value, and to apply an interpolation.

Dataset  ---  displays the active dataset name.  You can select a different dataset from the drop-down list.

Node Selection:

    Center Node  ---  move the sliders or type values to adjust the I, J, or K parameters of the center nodes, which are highlighted by a cross-hair in the view.

    Plane I, J, K  --- select the appropriate check box to define the parametric plane for which the cross-hair is drawn.

    X, Y, Z  ---  display the XYZ coordinates for the selected center node.

    Influence Range  ---  move the sliders or type values to adjust the cube geometry (the number of grid nodes in each direction).  The cube is highlighted as you make adjustments.  When the range is 0,0,0, no neighboring nodes are affected; only the center node is modified.

Interpolation Method:

    Select an algorithm from the drop-down list as follows:

    Constant  ---  applies the value of the center node to all nodes within the influence range.

    Metric Power  ---  type a value in the Metric Power text box.  (The power parameter defines how much each input data value affects the values of its nearby output points.  A power of ten is large.  A power less than one is small.  Small power is not recommended.  The power cannot be less than zero.)

    Fast  ---  interpolates with fewer input data points resulting in faster processing.  This is especially true for the Multiquadric, Thin-plate Spline, and Volume Spline algorithms.

    NOTE    When Fast is on, only the grid nodes immediately next to the edges of the cube are used as input points. The reinterpolated values deviate more from the previous values than when Fast is off.  When Fast is off, all grid nodes next to the cube surfaces are used as input points.

Attribute Values:

    Field|Value  ---  displays the data-field name(s) and values in the active dataset.

    New Value  ---  select the value you want to change and type a new value in this text box.

    Apply  ---  processes the interpolation.

    Undo  ---  undoes each interpolation in the order it was processed and resets the data-field value(s) and the influence range to their previous settings.

Organize Dataset

Lets you rearrange the order of the gridded geometric or data-field information.  Frequently, data imported from new sources through the ASCII to HDF translator has the grid entries ordered differently than Voxel Analyst expects, for example, output from FORTRAN programs.

If the loaded dataset contains iso-surfaces that are broken into small, scattered pieces with strong diagonal patterns, if the iso-surface is upside down or mirrored, or if axes seem to be exchanged, then you can use Organize Dataset to correct the problem.

Ordering or axis mirroring problems are shown with the diagonally patterned breakup of iso-surfaces or contours.  They can also be detected by inspecting the data with respect to any design elements to determine if the display makes sense in the context of the design elements.

TIP    Dataset > Edit Geometry > Organize = ALT+d,e,z

Organize Dataset Dialog Box

Use this dialog box to do the following:

•	Exchange the parametric axes (dimensions) of the dataset.

•	Reorder the coordinate data of a particular coordinate (X, Y, or Z) through mirroring along a parametric axis or by exchanging parametric (I,J,K) axes.

•	Mirror an attribute along a parametric axis.

•	Reorder an attribute by transposing parametric axes.

Dataset  ---  displays the active dataset name.  You can select a different dataset from the drop-down list.

Rearrange Grid:

    NOTE    These controls let you rearrange the IJK attributes associated with the XYZ coordinates of the active dataset model grid.

    Dimensions  ---  select this option to exchange the dimensions of the grid.

    X Coordinates, Y Coordinates, Z Coordinates  ---  select the appropriate option to rearrange the coordinate data of the selected coordinate only.

    Reverse  ---  select the check box or boxes that correspond to the parametric direction to be reversed.

    Exchange  ---  select the option that corresponds to the order in which you want the geometric coordinates to be arranged.

Rearrange Attribute:

    NOTE    These controls let you rearrange the data of the selected attribute.

    Attribute  ---  select an attribute from the drop-down list.  (The attributes differ according to the active dataset.)

    Reverse  ---  select the check box or boxes that correspond to the parametric direction to be reversed.

    Exchange  ---  select the option that corresponds to the order in which you want the attributes to be arranged.


Identity Matrix

Sets the active dataset orientation matrix (a 4 X 4 transformation matrix that positions the dataset geometry) to the identity matrix, thereby removing any rotation, scale, or translation represented in the matrix.

An identity matrix consists of all ones along the main diagonal and zeros everywhere else.  For example,

1  0  0  0

0  1  0  0

0  0  1  0

0  0  0  1

TIP    Dataset > Edit Geometry > Identity Matrix = ALT+d,e,i

NOTE    Identity Matrix does not require software prompts or dialog boxes.


Primary Matrix

Sets the active dataset orientation matrix to the matrix that transforms the dataset's points from MCSO (MGE Coordinate System Operations) primary coordinates to the active design file UORs (units of resolution).  The resulting equations are as follows:

Xuor = Xgrd * Xresolution + Xglobal_origin

Yuor = Ygrd * Yresolution + Yglobal_origin

Zuor = Zscale * Zgrd * Zresolution + Zglobal_origin

NOTE    Without MCSO coordinates, an identity matrix is substituted for the orientation matrix when Primary Dataset is selected.  See the Glossary in the Voxel Analyst Users Guide for more information on matrices.

Primary Matrix is useful for registering an unregistered dataset to a MicroStation design file.  For example, if you do not select a design file when converting sparse data to volume data, the resulting dataset is not registered with a design file and does not match the active design file elements.

Another example of an unregistered dataset is an Voxel Analyst-specific ASCII file in which MCSO primary coordinates are used for the Bounding_vol and Points_xor values instead of UORs.

Use this dialog box to define a color or, optionally, to define no color for a data value.  Shades of red, green, and blue are represented by numeric values ranging from 0.00 to 1.00 percent.  Any combination of red, green, or blue can be defined.  The color is interactively displayed.

NOTE    When no color is used, the values for the assigned ranges will not be represented by any color.  For display purposes only, it will be as if no data exists for these ranges.

Red, Green, and Blue  ---  type numeric values or move the sliders to define a color (0% red, 0% green, and 0% blue is black).  The color adjusts as you change the percentages.


Adjust Range

Lets you adjust the active color table data-value range (minimum and maximum data values) for each attribute in a selected dataset.  You can scale or clip values ranges according to new minimum and/or maximum data values that you define.

Scaling redistributes the data-value assignments in the associated color table over the new range and maintains the original number of colors (intervals).  Clipping cuts off the data values above and below the new range and does not maintain the original number of colors (intervals).  You also have the option to maintain the active color/data-value labels (if any).

Create Source Points

Lets you view sparsely or irregularly sampled source points as a Voxel Analyst graphic display.  This command performs a linear interpolation of the source points to their cubic weights or sizes. The interpolation is based on the minimum/maximum (low/high) attribute values and the data size values that you define.  The units are design file units, such as feet.  The resulting graphic display can be edited and manipulated like other graphic displays.

The coloring, interval shading, and material properties of the cubes are determined by the selected shading attribute and color table. The color table can be edited by clicking Edit.

Irregular Volume Dialog Box


Irregular Volume Dialog Box

Use this dialog box to select a shading attribute and color table and to define the bounding surfaces.  The bounding surfaces can be planes or other iso-surfaces.

If the bounding surface is a plane, define the pitch, yaw, and distance of the plane.  You can calculate the volume above (Top) the plane or the volume below (Bottom) the plane.  (Depending on how the dataset is oriented, a volume above the plane may appear in graphics to be below the plane, and vice versa.)

If the bounding surface is an iso-surface, select a bounding attribute and value, similar to a bounding attribute and value you select for calculating a regular volume.  You can calculate the volume in which the bounding attribute value is greater than or less than the iso-surface value, similar to calculating a regular volume. (Depending on how the dataset is oriented, a volume that is intended to be greater than the bounding iso-surface may appear in graphics to be less than the bounding iso-surface, and vice versa.)

An additional attribute can be selected for irregular-volume aggregate calculation.  The aggregate attribute can be the same as the shading attribute or it can be the same as the bounding attribute.

Interpolation Parameters Dialog Box

Use this dialog box to select optional interpolation restrictions and variation enhancement values.  You can set up interpolation parameters in advance before importing sample (source) point data. These parameters then become the default parameters for any source points subsequently imported.

Variation enhancement is important for interpolating flat output volume that has a much smaller Z range compared to the X,Y ranges. Without variation enhancement, the output interpolated values would show very little variations along the Z direction.  This is because the interpolation methods provided in Voxel Analyst are distance-based methods in which a small Z range contributes little weight to the interpolation compared to the larger X,Y ranges.  The calculated variation enhancement values are computed such that the small Z range provides the same contribution to the interpolation as the large X,Y ranges.

TIP    You can use the last-used interpolation parameters, or you can modify the parameters, or you can select a different algorithm and define new parameters.

Method:

    Select an interpolation method from the drop-down list as follows:

•	Metric  ---  a powered inverse-distance weighted approximation that can be used for very rough and unevenly distributed input data.  The output values are bounded by the range of the input data values.

     	Parameters:

     	The power parameter defines how much each input data value affects the values of its nearby output points.  A power of ten is considered to be large, while a power less than one is considered to be small.  (Small power is not recommended.) The power cannot be less than zero.

     	The background parameter is the value that the output values fade into when they are extrapolated.

     	The influence range parameter is a positive number that controls the distance at which the output values start fading.  (The influence distance is the influence range times the diameter of the minimum bounding sphere of the input data points.)  An influence range of 0.1 is considered small, while an influence range of 10 is considered large.  An influence range of 0 turns off the control.  When this happens, the extrapolated output values fade into the average value of the input data.

•	Multiquadric  ---  a second-order interpolation method that can be used for input data that is relatively smooth and relatively evenly distributed.  This method produces smooth varying output data.  However, the extrapolated output values may not be bounded. It is highly recommended that you turn the Clip Min and Clip Max check boxes (on the Convert Sparse Data to Volume Data dialog box) on to clip the output values to a physically realistic range.

     	Parameters:

     	The variance parameter is used to enhance the variations in the output data.  Valid input is any non-negative number.  However, it is not recommended to use any number that is larger than 0.5.  A large number could cause the interpolation to be unstable and to produce large errors.

•	Shepard  ---  an inverse-distance weighted approximation that can be used for very rough and unevenly distributed input data. The interpolated output values are bounded by the range of the input data values.

     	Parameters:

     	The background parameter is the value that the output values fade into when they are extrapolated.

     	The influence range parameter is a positive number that controls the distance at which the output values start fading.  (The influence distance is the influence range times the diameter of the minimum bounding sphere of the input data points.)  An influence range of 0.1 is considered small, while an influence range of 10 is considered large.  An influence range of 0 turns off the control.  When this happens, the extrapolated output values fade into the average value of the input data.

•	Thin-plate Spline  ---  used for input data that is relatively smooth and relatively evenly distributed.  This method minimizes the curvatures in the output data.  The output values are not bounded when extrapolated.  It is highly recommended that you turn the Clip Min and Clip Max check boxes (on the Convert Sparse Data to Volume Data dialog box) on to clip the output values into a physically realistic range.

•	Volume Spline  ---  a generalization of the cubic splines that can be used for input data that is relatively smooth and relatively evenly distributed.  This method can generate smooth varying output volume.

     	When extrapolating, this method could extend output values beyond the input value range.  It is highly recommended that you turn the Clip Min and Clip Max check boxes (on the Convert Sparse Data to Volume Data dialog box) on to clip the output values to a physically realistic range.

See the Voxel Analyst Users Guide for more information on interpolation methods.

    Parameters:

        Displays the parameters (where applicable) and the parameter values of the selected interpolation method.  You can modify the default values by typing different values.

        Default  ---  resets the parameter values to the default values.

    Apply Logarithms to Data  ---  compresses the data range to a smaller scale.  This is useful for handling large data ranges, for example, a range of 0 - 4 million can be compressed to a smaller range.  The output logarithmic data cannot be converted back to non-logarithmic.

Restrictions:

    The following controls let you set up restrictions that are applied to the input source points during interpolation.  The restrictions can be combined, with the exception of the two local restriction, which are mutually exclusive.  (The result of a local restriction is that the output data points are centered around a central grid node.)

    Use Sparse Points within MBV Only  --- interpolates only the sparse data points within the minimum bounding volume (MBV) defined on the Convert Sparse Data to Volume Data dialog box.

    Apply Local Restriction  ---  enables two types of restrictions that can be applied to the input source points: By Percentage of MBV and By HDF File.

    By Percentage of MBV  ---  enables the X(K), Y(J), and Z(I) text boxes.

    X(K), Y(J), Z(I)  ---  type a local restriction as a percentage of the MBV of the input source points expressed as XYZ values.  Only those input values that occur within the specified XYZ are interpolated.

    By HDF File  ---  enables the text box.  Type the name of an .hdf file to be applied as a restriction on the input source points.  Only those input values that occur in the selected file are interpolated.

    Browse  ---  opens the Open dialog box , which lets you select an .hdf file for the By HDF File restriction.

    Apply Symbolic Restriction  ---  enables symbolic restriction that can be applied to the input source points. This restriction ignores any rotation of the input source points and limits the interpolation to the symbolic fields defined in the input Geometry file.

    Symbolic Field  ---  type a symbolic field to be applied as a restriction on the input source points, or select a symbolic field from the drop-down list.

    Background Value  ---  type a value that will be used to create background data points for a lone input data point.

Variation Enhancement:

    Auto  ---  enables variation enhancement using the default values shown in the X(K), Y(J), and Z(I) text boxes.

    Keyin  ---  type variation enhancement values in the X(K), Y(J), and Z(I) text boxes.

IJK

A unique integer triplet that identifies every grid location in a 3-D volume.  A 3-D volume is defined using a 3-D grid.  Each data point in the volume lies on a grid-intersection.  Each grid intersection has the 3-D geographic coordinate X, Y, and Z associated with it.  Therefore, the coordinates of each grid-intersection can be written as (X[I,J,K], Y[I,J,K], Z[I,J,K]), so that each X,Y,Z coordinate is a function of all three I,J,K integers or parameters.  You use I,J,K parameters in the creation of graphic displays:  adjusting the parametric ranges (the minimum and maximum I, J, and K values) in graphics displays allows you to evaluate and analyze data variation.

An irregular grid is also referred to as a rectilinear grid.  See the Voxel Analyst Users Guide for an example of an irregular grid.

irregular volume

The volume that can be generated from the results of querying multiple iso-surface or bounding planes in a 3-D volume dataset.  For example, you can find the volume of all values greater than (>) Data Field 1, less than (<) Data Field 2, and bounded by a property line.

iso-parametric

A graphic of an IJK parametric surface showing data variation in a selected volume or dataset.  Differs from a cutting plane in that it follows the grid lines.

iso-solid

A graphic of a 3-D solid that represents all points in a volume between two values of a selected data field or characteristic.

For example, the data_type command can accept the keywords BYTE, U_BYTE, SHORT, U_SHORT, INT, U_INT, FLOAT, and DOUBLE.

levels

The display design plane consists of a multilevel display structure.  Voxel Analyst graphic displays can be organized in any fashion on 63 levels, although no graphic can span two levels.  Only one level can be active at a time, but any combination can be displayed or blanked from the screen.  The active level must be displayed.

lock point

The corner of a graphic display used to determine the axis to be used to

rotate the display or to scale the display.  The corner is identified by clicking it.
