thanks to Nicholas Bishop for finding the cause of the problem.
don't tesselate on load, this means me->mface will be NULL by default.
we may need to have this set if existing uses of this array are not resolved before release - so add a define USE_TESSFACE_DEFAULT, to change this easily.
this is a rather indirect fix - need to take care here.
- use SMOOTH flag for edges (removed sharp flag and inverted), gives us an extra flag slot available.
- rename BM_edge_is_nonmanifold --> BM_edge_is_manifold and invert result, BM_vert_is_nonmanifold too.
made some small edits
- removed changes to AVI reading since the data types are apart of the format spec.
- absf -> abs for a double value in render code.
*operator now works with few limitations:
-still no preview(will be back soon)
-rotation will not work if only one uv is stitched between islands(will need method to calculate uv normal for manifold)
Also fixed island calculation for UvElements, fixes a crash when uv sculpting with "Sculpt all islands" turned off
In preparation for code in progress that uses lists
allocated out of the knife arena. This also makes
existing code more readable and understandable IMO.
Also removed an #if'd out function that will not
ever be needed.
This is a kind of simplification/cleanup tool which joins adjacent faces and edges based on the angle.
I've written this as an exercise (since I havnt written a bmesh operator before), and because quite a few users were asking for the dissolve operator to be extended, but I think this kind of functionality needs its own operator.
access from specials menu and mesh menu.
notes
* this exposed a bug in angle_v3v3v3(). will merge fix into trunk after release.
* added utility function BM_vert_edge_angle(), to get the angle between 2 connecting edges of a vert.
added BM_mesh_elem_flag_enable_all (only had disable function), and add
argunt for vert/edge/face type.
use these functions from EDBM_flag_enable/disable_all (had duplicate
code).
`_set` suffix was used in two ways (confusing)
* to set a flag to be enabled.
* to set a value passed as an argument.
now use enable/disable rather then set/clear for functions which change flags.
also remove BME_weld.c, the file didnt contain much code and the current extrude works well
* add DM_to_bmesh_ex, DM_to_bmesh for converting a derived mesh to a BMesh (rather than a BMEditMesh)
* have a generic variable for allocsize: bm_mesh_allocsize_default, rather than copying the values about.
Issue was caused by making and loading editMesh in drop_named_image_invoke,
which lead to freeing/changing pointers used by CustomData layers. Some of
this pointers might be used by DerivedMesh, so we need to update DerivedMesh
after loading EditMesh.
These changes are to make the bmesh api more consistent and easier to learn, grouping similar functions which is convenient for autocomplete.
This uses similar convention to RNA.
* use face/loop/edge/vert as a prefix for functions.
* use 'elem' as a prefix too for functions that can take any type with a BMHeader.
* changed from camel case to underscore separated (like RNA).
