-
- This program is a little utility to convert 3D files to a number of
- other 3D formats. It can generate smooth triangles for those formats
- that support it, allowing you to specify the angle under which the
- faces should be smoothed.
-
-
- INPUT
-
- This version supports the following input formats:
-
- - .RAW
- Simple RAW format in the form: pnt0 pnt1 pnt2
- Multiple objects are supported if the file is in the form:
- NAME_OBJECT1
- pnta00 pnta01 pnta02
- pnta10 pnta11 pnta12
- pnta20 pnta21 pnta22
- ...
- NAME_OBJECT2
- pntb00 pntb01 pntb02
- pntb10 pntb11 pntb12
- pntb20 pntb21 pntb22
- ...
-
- see chess.raw for an example.
-
- - .3DS
- Binary mesh format for 3D Studio (Trademark ...)
- only objects with faces are supported
- Highlight output does not work (convert to RAW first and then to OBT).
-
- - .OBJ
- Binary mesh format for Imagine 2.x/3.x (Trademark ...)
- only objects with faces are supported
- Tip: If you have a object generated in the form - editor, load it
- into the detail editor, select it, use the "merge" command and
- save it as a ".obj" file. Now the object is ready for converting.
- Tip: If you have object files with the extension .iob (Amiga
- extension ??) rename it to ".obj".
- Highlight output does not work (convert first to RAW and then to OBT).
-
-
- OUTPUT
-
- This version supports the following output formats:
-
- - .RAW
- The converter can generate a smooth RAW from an unsmoothed
- RAW and vice versa.
- - .UDO/.INC
- Userdefined Object format for Moray V2.x and a inc file for
- POVRAY or POLYRAY.
- The converter writes a UDO file and a corresponding POV-Ray or
- Polyray include file, generating triangles (poly's) and
- smooth_triangles (patches). Use the /e parameter to reduce
- the edge count if you are getting too many edges in the UDO file.
- A value of /e5 will retain just about all edges that are not coplanar.
- A value of /e60 will throw out lots of edges and retain only pretty
- sharp contours.
- Additional wired and wired/blobby output for povray is supported
- - .ASC
- ASCII object format for 3D Studio. Hidden edges are supported
- - .OBT
- ASCII object format for Highlight Pro
- Converts only RAW to OBT
- - .RPL
- ASCII object macro format for Real 3D. (Version 3.12)
- - .3DS
- Binary object format for 3D Studio. Hidden edges are supported
- - .OBJ
- Binary object format for Imagine.
- Hidden edges (Quick edges) and smoothing (Sharp Edges) are supported
- - .RWX
- ASCII objectformat for RenderWare
- - .WRL
- ASCII objectformat for VRML 1.0
-
- If inputtype and outputtype are the same, $$$ is used as filename.
-
-
- Usage:
- 3dto3d xxxx [options]
- Example:
- 3dto3d chess /e20 /t3
- Options:
- /svalue (value = Smoothing Angle in degrees, default 70.0°)
- - smoothes tri's with a normal angle below value
- affects only output of /o1, /o2, /o3, /o10
-
- /evalue (value = Edge Detect Angle in degree, default 1.0°)
- - throws out edges with an angle below value
- affects POV/UDO, 3DS and OBJ files created with
- /o2, /o3, /o4, /o7, /o8, /o9, /o10
-
- /v(Verbose on)
- - gives status messages on the progress of the conversion
-
- /u(Unify Mesh on)
- - changing all normal vectors pointing outside
-
- /j(write absolute path to udo/inc file)
-
- /rvalue (value = radius for wireframe objetcs, default 1.0)
-
- /tvalue (value = Swapmode)
- value = 0 normal (default);
- value = 1 swap X <-> Y;
- value = 2 swap X <-> Z
- value = 3 swap Y <-> Z
- - swaps axis
-
- /xvalue (val = sizingvalue, default 1.0)
- - sizes the mesh.
- values from 0.0 to 1.0 shrink the mesh
- values greater than 1.0 enlarg the mesh
- negative values mirror the mesh
-
- /ivalue (value = Inputtype)
- value = 0 RAW (default)
- value = 1 3DS (3D Studio)
- value = 2 OBJ (Imagine)
-
- /ovalue (value = Outputtype)
- value = 0 RAW
- - makes a pure RAW file for testing
- form: pnt0 pnt1 pnt2
-
- val = 1 Smoothed RAW
- - makes a smoothed Raw file
- form: pnt0 norm0 pnt1 norm1 pnt2 norm2
-
- val = 2 UDO + POV/INC <Moray/Povray>(default)
- - makes a POVRAY include File with triangles
- and a MORAY UDO file
-
- val = 3 UDO + POLY/INC <Moray/Polyray>
- - makes a POLYRAY include File with triangles
- and a MORAY UDO file
-
- val = 4 ASC <3DStudio>
- - makes a 3DStudio ASC file
- - /e affects hiding edges for better viewing
-
- val = 5 OBT <HighLight>
- - makes a HighLightPro OBT file
- (only works with RAW files)
-
- val = 6 RPL <Real3D Macro>
- - makes Real3D RPL file, ASCII Macro
-
- val = 7 3DS <3DStudio>
- - makes a 3DStudio binary file
- - /e affects hiding edges for better viewing
-
- val = 8 UDO + POV/INC <Moray/Povray>(wire)
- - makes a POVRAY include File
- and a MORAY UDO file
- For every edge in the object a cylinder
- and for every vertex a sphere is output
- The radius is controlled via /r
- /r1.0 for radius 1.0
- Can be used to make a 'real' wireframe object
-
- val = 9 UDO + POV/INC <Moray/Povray>(blobbywire)
- - makes a POVRAY include File
- and a MORAY UDO file
- For every edge in the object a line of blobs
- and for every vertex a blob is output
- The radius and the spacing is controlled via /r
- /r1.0 for radius 1.0
-
- val = 10 OBJ <Imagine Object>
- - makes a Imagine binary file
- - /e affects hiding edges for better viewing
- (Quickedges)
- - /s affects smoothing edges for better viewing
- (Sharpedges). A low value makes more edges sharp.
-
- val = 11 RWX <RenderWare Object>
- - makes RenderWare object file, ASCII
-
- val = 12 WRL <VRML 1.0 Object>
- - makes VRML object file, ASCII
-
