Model Page
The Model page is for modeling simple
objects. Five types of objects can be constructed directly:
- Point: a point object is a list of points. It is for grouping
points into meaningful shapes.
- Line: a line object is a list of points representing a polyline.
- Grid: a grid object is a grid of points arranged in rows. It is
for constructing surface meshes.
- Patch: a patch object provides a way to exclude any un-wanted triangles from
its triangle mesh.
- Light: to preview a created model in the Preview window, you need to create
a light object.
The Model page contains the following elements:
- object type notebook: Selecting a subpage determines the type of object
under editing:
- Point subpage: for constructing and editing a Point object.
- Line subpage: for constructing and editing a Line object.
- Patch subpage: for constructing and editing a Patch object.
It contains a Working field for selecting a working image and
a Texture field for selecting a texture image. A patch can be
created by selecting a set of points, and optionally,
points for excluding triangle.
- Grid subpage: for constructing and
editing a Grid object.
This page contains a Texture image field for
selecting image as a texture. It also has a 'Row' field for selecting
a row of the grid object for editing.
- Light subpage: light can be created with a Light
object. You can adjust its color by changing the
value of the R (red), B (blue), and G (green) fields. You can
also change the location of the light in the world coordinate
system by entering value for the X,Y,Z Location fields. You
usually need to create lights in order to view objects in
the Preview window.
- Current Object field: It shows the object under editing.
- To select an existing object, press the down arrow at
the right side of the field
to pull down a list of objects of the selected type.
Click on an
object name to select that object for editing.
- To create a new object: type in a name and press 'Return'. This
will create a new object.
- Delete button: pressing it deletes the current object.
- Validate button: pressing it validates
the current object.
- Validate All button: pressing it validates all the objects.
- Preview button: invokes the Preview window.
- Material button: invokes the Material dialog.
