- Fixes by Jean-Michel Soler: mod_ai2obj.py, mod_svg2obj.py; - Fixes by Campbell Barton: obj_import.py; - Small fix to mod_meshtools.py (fixes bug #1605: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1605&group_id=9); - Updates by Jean-Baptiste (Jiba) to his blender2cal3d.py; - Updates to all his import / export scripts (added doc data) by Anthony D'Agostino; - Update to off_import: support for uv data, by Arne Schmitz. BPython: - Removed Object.get and .getSelected (deprecated long ago, we use .Get and .GetSelected) -- fixes #1861: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1861&group_id=9 - Applied patch by Michael Reimpell: quat.c - fix for wrong initialization with newQuaternionObject; Mathutils documentation improvements. - Stani reported a wrong return msg in IpoCurve.Get (that is unimplemented). Thanks to all coders mentioned above!

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.
