- tiny updates for better behavior, unix line endings, cvs Id tags; - Updated DX7 exporter (thanks to author Ben Omari who's also working on a DX8 one); - added sysinfo script; Interface (scripts): - changed behavior for which win is chosen for script guis: Now there's a smarter order, guis will use either: - Scripts win - Buttons win (if not a script from groups Wizards or Utils) - Text win - Closest bigger area - Added a button to the scripts header so that it's faster to return to the buttons win (this can be made general), if that was the previous win used.

# === Matrix Differences between Blender & trueSpace ===
|
|
#
|
|
# 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 is a little confusing.
