fixed many errors in Cal3D that didnt show up with the testmodel I was using.
Mostly problems with vertex index, and splitting off new verts. removing truespace_export.py truespace_import.py, (decieded by letterrip and myself) both truespace and blender have enough formats in common that we dont need to support this format thats spesific to truespace and not used for 3d data interchange.

This script exports meshes to TrueSpace file format.
|
||||
|
||||
TrueSpace is a commercial modeling and rendering application. The .cob
|
||||
file format is composed of 'chunks,' is well defined, and easy to read and
|
||||
write. It's very similar to LightWave's lwo format.
|
||||
|
||||
Usage:<br>
|
||||
Select meshes to be exported and run this script from "File->Export" menu.
|
||||
|
||||
Supported:<br>
|
||||
Vertex colors will be exported, if they are present.
|
||||
|
||||
Known issues:<br>
|
||||
Before exporting to .cob format, the mesh must have real-time UV
|
||||
coordinates. Press the FKEY to assign them.
|
||||
|
||||
Notes:<br>
|
||||
There are a few differences between how Blender & TrueSpace represent
|
||||
their objects' transformation matrices. Blender simply uses a 4x4 matrix,
|
||||
and trueSpace splits it into the following two fields.
|
||||
|
||||
For the 'Local Axes' values: The x, y, and z-axis represent a simple
|
||||
rotation matrix. This is equivalent to Blender's object matrix before
|
||||
it was combined with the object's scaling matrix. Dividing each value by
|
||||
the appropriate scaling factor (and transposing at the same time)
|
||||
produces the original rotation matrix.
|
||||
|
||||
For the 'Current Position' values: This is equivalent to Blender's
|
||||
object matrix except that the last row is omitted and the xyz location
|
||||
is used in the last column. Binary format uses a 4x3 matrix, ascii
|
||||
format uses a 4x4 matrix.
|
||||
|
||||
For Cameras: The matrix here gets a little confusing, and I'm not sure of
|
||||
how to handle it.

This script imports TrueSpace files to Blender
|
||||
|
||||
TrueSpace is a commercial modeling and rendering application. The .cob
|
||||
file format is composed of 'chunks,' is well defined, and easy to read and
|
||||
write. It's very similar to LightWave's lwo format.
|
||||
|
||||
Usage:<br>
|
||||
Execute this script from the "File->Import" menu and choose a TrueSpace
|
||||
file to open.
|
||||
|
||||
Supported:<br>
|
||||
Meshes only. Supports UV Coordinates. COB files in ascii format can't be
|
||||
read.
|
||||
|
||||
Missing:<br>
|
||||
Materials, and Vertex Color info will be ignored.
|
||||
|
||||
Known issues:<br>
|
||||
Triangulation of convex polygons works fine, and uses a very simple
|
||||
fanning algorithm. Convex polygons (i.e., shaped like the letter "U")
|
||||
require a different algorithm, and will be triagulated incorrectly.
|
||||
|
||||
Notes:<br>
|
||||
There are a few differences between how Blender & TrueSpace represent
|
||||
their objects' transformation matrices. Blender simply uses a 4x4 matrix,
|
||||
and trueSpace splits it into the following two fields.
|
||||
|
||||
For the 'Local Axes' values: The x, y, and z-axis represent a simple
|
||||
rotation matrix. This is equivalent to Blender's object matrix before
|
||||
it was combined with the object's scaling matrix. Dividing each value by
|
||||
the appropriate scaling factor (and transposing at the same time)
|
||||
produces the original rotation matrix.
|
||||
|
||||
For the 'Current Position' values: This is equivalent to Blender's
|
||||
object matrix except that the last row is omitted and the xyz location
|
||||
is used in the last column. Binary format uses a 4x3 matrix, ascii
|
||||
format uses a 4x4 matrix.
|
||||
|
||||
For Cameras: The matrix here gets a little confusing, and I'm not sure of
|
||||
how to handle it.
