4d1d50ea8b Fix bevel crash #33801, when first edge of a vertex is wire. 2013-01-08 03:30:31 +00:00

c3b5c726c7 * Fix for #31581. The issue was that we scaled the face prior to 
projecting it. The original paper suggests to simply interpolate between
the two points of an edge if the distance of the point to that edge is
smaller than a threshold.

* Fixed both 3D and 2D code to utilize this. Possibly other places in
blender where this scaling is done will have to be adjusted.

* Changed vertex interpolation to use 2D interpolation, since it already
did projection on plane and 2d calculations are faster.

* Also added notifier on hard recalc when uvcalc_transfor_correction is
used. Results in instant feedback on UV editor when edge sliding.

b2f6e6b113 code cleanup: BM_face_create_ngon() 
Change some of the paranoid checks into an assert since they should never happen.

in fact a more general bug in BM_face_create_ngon() where edges containing the same vertex multiple times were not accounted for.

c2839bfe76 add option WITH_SYSTEM_BULLET to link against the bullet installation found on the system. 
Note: this doesn't work yet for everything with latest stable bullet (2.81), need to look into why and likely apply some patches upstream.
However I managed to link blender by disabling some features, likely it can be made to work without too much trouble.

2e9cb31c02 Add BMLog for efficiently storing changes to vertices and faces 
The BMLog is an interface for storing undo/redo steps as a BMesh is
modified. It only stores changes to the BMesh, not full copies.

Currently it supports the following types of changes:
- Adding and removing vertices
- Adding and removing faces
- Moving vertices
- Setting vertex paint-mask values
- Setting vertex hflags

2d39e46414 Add BM_edge_calc_squared_length() query function 
Same as BM_edge_calc_length(), but avoids square root for cases where
only comparison is needed.

4e5d5e0d84 Add 'vertex_only' option to bevel tool. 
Right now, changing segments to > 1 doesn't do anything,
but intend to work on making that cause rounded corners.

99433a3466 minor bmesh improvements 
- use 2 omp sections for vert -> (edge, face) selection flushing.
- dont use face-loop iterator for cddm_from_bmesh_ex conversion to give some speedup (some modifiers use this).
- use float(*)[3] for functions that return coords.

3d69dbd44a use openmp to thread some common bmesh operations 
- BM_mesh_elem_toolflags_ensure / bmo_flag_layer_alloc / bmo_flag_layer_free / bmo_flag_layer_clear
- BM_mesh_select_flush
- EDBM_index_arrays_init

notes:
- mostly use openmp `sections` to split operations on vert/edge/face since this is a fairly minor change.
- split tool flag pool in 3, this means we can allocate exact sizes needed and iterate on them in threads without alloc'ing.

0bca862e9c Bevel: fix 'causing artifacts' bug 33245. 
Really was caused by a previous bevel making
a two-edged face, which caused other faces to
be dropped when copying a bmesh.
The quadstrip code needed to be more careful
to avoid creating two-edge faces.

11e87d118e Bevel: fix for bulging part of bug 33280. 
Bulging still happens, but fixed the cases where it was obvious
because it destroys an otherwise straight 'pipe' by snapping
the vertex mesh points to that pipe.
