this commit makes vertex paint check if it needs to rebuild the modifier stack when painting.
- when painting with no modifiers, do partial updates from polys to tessfaces while painting, skip re-tesselation.
- when painting onto a modified mesh, dont bother adjusting tessface colors - since the modifier stack will do this anyway.
both cases should be faster then before.
this will be needed for tangents and most likely hair if its to load correctly from trunk.
disabled for now until this is working correctly - hair still needs more work.
- reserve the array sizes to avoid re-allocing (even though its a lower limit it still helps)
- increase array size in larger steps then 1 by 1.
- avoid a few array lookups.
- use more obvious variable naming to make the function more readable.
comparing bmesh to trunk, mesh_calc_normals() in bmesh is a much more comprehensive function, calculating mpoly,mface normals, where trunk only calculated vertex normals.
renamed:
* mesh_calc_normals() --> mesh_calc_normals_mapping_ex
* mesh_calc_tessface_normals --> mesh_calc_normals_tessface() - only calculates normals from tessface
* added mesh_calc_normals() - only calculates normals from poltys
this way we can have mesh_calc_normals() remain fast for parts of the code which only need vertex normals to be updated.
only refactor, no func changes- didnt replace mesh_calc_normals_mapping_ex() with mesh_calc_normals() anywhere yet.
Warning! Tesselation uvs or vcol data got out of sync, "had to reset!
This would happen on every editmode edit with UV's and wasn't too reassuring that blender was handling uvs/vcols correctly.
From looking into the problem I found that creating the undo mesh would act as if it was tessellating the existing mesh each time and complain that the data was out of sync, when infact the mesh was just created and being filled in.
Also, allocating uv and vcol customdata arrats for tessfaces isn't needed for undo mesh, so save some memory and dont allocate these in the first place.
- editmesh smooth & subdivide were using old mirror axis flag still.
- removed colbits from outliner and object code.
- commented some other parts of the code which access deprecated members and aren't called anywhere.
