# Things TODO for a next release:
+# - Shadeless shader
# - FIX the issue with negative scales in object tranformations!
# - Use a better depth sorting algorithm
# - Review how selections are made (this script uses selection states of
# primitives to represent visibility infos)
-# - Use a data structure other than Mesh to represent the 2D image?
+# - Use a data structure other than Mesh to represent the 2D image?
# Think to a way to merge (adjacent) polygons that have the same color.
# Or a way to use paths for silhouettes and contours.
# - Consider SMIL for animation handling instead of ECMA Script? (Firefox do
# Changelog:
#
# vrm-0.3.py - ...
+# * Adapted to blender API 2.45
# * First release after code restucturing.
# Now the script offers a useful set of functionalities
# and it can render animations, too.
# * Remove the real file opening in the abstract VectorWriter
# * View frustum clipping
# * Scene clipping done using bounding box instead of object center
+# * Fix camera type selection for blender>2.43 (Thanks to Thomas Lachmann)
+# * Compatibility with python 2.3
+# * Process only object that are on visible layers.
+# * Saving config to registry (Thanks to Thomas Lachmann for a draft
+# implementation)
