# Things TODO for a next release:
-# - Switch to the Mesh structure, should be considerably faster
-# (partially done, but with Mesh we cannot sort faces, yet)
+# - Use multiple lighting sources in color calculation,
+# (this is part of the "shading refactor") and use light color!
+# - FIX the issue with negative scales in object tranformations!
# - Use a better depth sorting algorithm
+# - Implement clipping of primitives and do handle object intersections.
+# (for now only clipping away whole objects is supported).
# - Review how selections are made (this script uses selection states of
# primitives to represent visibility infos)
-# - Implement clipping of primitives and do handle object intersections.
-# (for now only clipping for whole objects is supported).
-# - Implement Edge Styles (silhouettes, contours, etc.) (partially done).
-# - Implement Edge coloring
-# - Use multiple lighting sources in color calculation
-# - Implement Shading Styles? (for now we use Flat Shading).
# - 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.
+# Think to a way to merge (adjacent) polygons that have the same color.
# Or a way to use paths for silhouettes and contours.
-# - Add Vector Writers other that SVG.
# - Consider SMIL for animation handling instead of ECMA Script? (Firefox do
# not support SMIL for animations)
-# - FIX the issue with negative scales in object tranformations!
+# - Switch to the Mesh structure, should be considerably faster
