ec834f8234 Bug fix, IRC report. 
Mesh with very strange topology makes loop-select (ALT+select) crash.
Missing NULL check for do-while loop that can return NULL.

For Campbell: here's the file to check: http://www.pasteall.org/blend/21576

0ff22044cd Support for bridge tool subdivisions, smoothing and shape along the profile. 
also added the underlying subdivision as a standalone operator in the edge menu, named: subdivide edge-ring.

b73c821b5d fix for BM_mesh_edgeloops_find(), could give edge loops with one vert. (caused bridge to crash sometimes) 2013-05-17 12:11:34 +00:00

b31e03fdd1 refactor bmesh edge loop walker, 
was getting too complicated handing different cases at once, split out boundary case into its own branch.

92da9792fe fix for strange behavior with loop select involving ngons,

b48deabf4e new bevel: fix for crash in merge, could result in collapsing faces being invalid. rather then splice each edge, use weld_verts operator which handles removing degenerate geometry. 2013-05-13 14:31:45 +00:00

e40d403e43 fix for bridge flipping, loops pointing away from eachother (over 90d difference) would flip 
now check the loops are facing eachother, taking their relative positions into account.

55f929ab3d - add generic edge-loop utility functions for bmesh. 
- rewrite bridge tool to use the new functions (using edge & vertex arrays was quite cumbersome).

4c042f2145 bmesh: optimize bmesh_vert_separate, redice allocs (best cast it wont do any allocs). 
gives approx 16% overall speedup to edgesplit modifier.

also reduce size of smallhash stack, was 521, which got doubled and was quite large on the stack. reduce to 64.

2e0f741d01 can't use alloca in inline functions (fills up stack - I thought compiler would be smart here). 
also reserve the exact number of vert/face/edge/loops when creating a bmesh during undo.

6f8c29ab0b fix for 2 errors introduced since release 
- shape key NULL pointer dereference.
- use uninitialized variable for bmesh free.

also update credits and merge dissolve flag assignment.

0ee45c9301 more optimal method of calculating the normal for the solidify modifier. 
When adding 2 unit length vectors, the length can be used to calculate the angle.

8ac2fee57a minor speedup for bmesh - add CustomData_bmesh_free_block_data(), use 
when the block would be immediately allocated again.
