248b2fc6d6 bmesh-decimator update 
- 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.

203ff71b9e bmesh decimate fixes 
- don't collapse boundary verts into non boundary edges (was ugly causing spikes)
- handle degenerate cases better, rather then removing double edges after collapse, check before collapsing that there won't be any degenerate faces/edges.

d599b643b7 style cleanup: bge, switch statements mostly. 
also left bmesh decimator on in previous commit.

3da4b08110 bmesh-decimator, skip recalculating face normals on each edge collapse. (they are not used so faster to avoid) 2012-10-20 18:12:22 +00:00

eee64aeccf bmesh-decimate now only does CustomData_has_math for loop layers, add CustomData_has_interp() for vert & edges. 2012-10-20 17:39:56 +00:00

8944dab58a bmesh decimator support for loop & edge customdata. (most importantly UVs and vertex colors). 2012-10-20 17:31:07 +00:00

d20128bbbc fix for BM_edge_other_loop() not working right (own error in recent commit), and add new function BM_vert_step_fan_loop() for stepping around the loops of a face fan with manifold edges. 2012-10-20 16:48:04 +00:00

deeecc2029 code cleanup: remove unused members of BMIter struct to save some space. (this iterator is used everywhere). 
also rename vars in the struct.

23d43396ff code cleanup: quiet -Wshadow warning, var name changes for splice functions and add assert for BM_edge_splice() when edges don't use the same vertices. 2012-10-20 09:56:40 +00:00

a7a723283b add BM_edge_find_double() and use in bmesh decimator to fix crash. 2012-10-20 09:48:41 +00:00

9f8070d047 code cleanup: 
- define array sizes for functions that take vectors.
- quiet some -Wshadow warnings.
- some copy/paste error in readfile.c made it set the same particle recalc flag twice.

e527ce552e add option to initialize heap with a known number of elements, since this may be known in advance - it avoids re-allocing too much. 2012-10-19 10:40:32 +00:00

e648542872 decimate modifier rewrite to use bmesh (#ifdef-disabled by default for now). 
- maintains quads & ngons
- supports some customdata (weight paint for example works fine).

TODO
- add suppory for loop data (UV's / VCol's).
- outputs invalid geometry when heavily reducing some meshes, needs to be made stable in these cases.

9b07c98bb4 code cleanup: minor style change & quiet warning, also add assert for BM_vert_splice() to check for invalid use. 2012-10-19 03:07:58 +00:00

0c2a1500f2 minor changes 
- stub from last commit was incorrect (copied old docs)
- decimator was making copy of quadric for no reason.
- correct typo

12a8c19956 un-subdivide bmesh operator, useful for making lower polygon versions of models, can give nicer results then edge collapsing which tends to give a lot of sharp triangles. 
works on edges and faces, has iteration option to further reduce the poly count.

access from the edge menu, under subdivide.

eb771c78cd fix for free NULL pointer in BM_vert_splice() and BM_iter_as_arrayN() failed with BM_VERTS_OF_MESH/BM_EDGES_OF_MESH/BM_FACES_OF_MESH. 2012-10-16 14:35:37 +00:00

aacdd76c06 fix for 2 cases BM_disk_dissolve() could fail/assert. 
- when there was a vertex with 2 boundary edges and one manifold edge (vert at the boundary between 2 quads) it could assert.
- when there is a vertex with 2 boundary verts connected that both use the same face, it would do nothing.

1de76baf88 Add BMesh and WM symmetrize operators 
* The symmetrize operation makes the input mesh elements symmetrical,
  but unlike mirroring it only copies in one direction. The edges and
  faces that cross the plane of symmetry are split as needed to
  enforce symmetry.

* The symmetrize operator can be controlled with the "direction"
  property, which combines the choices of symmetry plane and
  positive-negative/negative-positive. The enum for this is
  BMO_SymmDirection.

* Added menu items in the top-level Mesh menu and the WKEY specials
  menu.

* Documentation:

643f331cb5 Rip-fill mesh tool (option for rip operator) 
Alt+V will fill the area inbetween the ripped faces - a bit like extrude.
faces are flipped to match existing geometry and customdata (uv, vcols etc) is copied from surrounding geometry too.

8b7f410f95 Code cleanup - silence some "uninitialised" warnings in BMesh code 
There are still a lot more in bmo_bevel.c and bmo_extrude.c, but those don't
seem that easy to fix.
