selected linked in face mode was crashing. (needs bmesh operator flags)
also some style edits, remove unused includes and change triangulate modifiers use_beauty to a flag.
Useful for bump map baking where a consistent triangulation should be enforced when baking/exporting/importing, to avoid artifacts caused by a different triangulation of the mesh by that which was used for baking by internal/external tools.
documentation is here http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.65/More_Features
Will probably add some pictures too to demonstrate the issue that is solved more clearly.
Currently using the skin modifier icon, will soon change that.
Review by Brecht, thanks!
Armature modifiers added via Ctrl-P operation will no longer have "envelope"
deforms enabled. This helps cut down the number of unintended deformations
arising from rouge-sized envelopes or stray control bones.
some of these were only returning a boolean, others returned a count even though only a boolean was needed.
split some of the functions in two as well where check/count are both needed.
reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer
for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).
as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
- when an edge exists across a quad, dont attempt to triangulate it. (such a case isn't so common anyway)
- silly mistake when checking if anything needed to be done in the modifier, percent was being checked for 1.0 even when not used.
- use unsigned ints only (where mixing signed/unsigned)
- turn heap_swap into an inline function, add SWAP_TVAL macro to swap values using a temp value as storage.
- added type checking SHIFT3/4 macros
also style cleanup for CTR_Map
- update face normals when triangulating.
- avoid divide by zero when interpolating customdata on a zero length edge.
- replace zero float comparisons with fabsf() < FLT_EPSILON to avoid numeric error.
also renamed BLI_heap_empty() --> BLI_heap_is_empty() so its obviously readonly function.
