* fill-holes operator now takes advantage of new edge-net fill, works in many more cases then it did before.
* face-create that uses edge-net now initializes the normals based on surrounding geometry, only running normal calculation if there are no connected faces for a reference.
previous code created faces with mixed face-flipping and could get very slow,
test with ~60,000 edges here hung my system for over 2min (didnt wait for it to finish), new code executes in about 1 second.
new code doesn't attempt to flip faces correctly, its quite involved to do so, especially when the new faces are not created adjacent to eachother.
so simpler to calculate normals afterwards.
In this case edgenet_fill operator failed and it would fallback to filling as unordered vertices which was mostly fine but failed on some concave loops.
Add a new bmesh operator 'edgeloop_fill' fills in closed loops even if they don't make a valid edge-net.
Thanks for Sergey for finding the bug & patching, This fix works a bit differently.
Theres no need to allocate the customdata in the first place - since its written into. So add a flag for vert/edge/face/loop creation functions so they can skip customdata creation.
- BMO_slot_copy now only copies compatible elements.
other minor changes
- don't use text.format(...), convention for UI scripts is C style string formatting.
- rename bmo_edgenet_prepare --> bmo_edgenet_prepare_exec
- float/double warning in bevel.
some of these were only returning a boolean, others returned a count even though only a boolean was needed.
split some of the functions in two as well where check/count are both needed.
Added four new functions as shortcuts to creating GHashes that use the
standard ptr/str/int/pair hash and compare functions.
GHash *BLI_ghash_ptr_new(const char *info);
GHash *BLI_ghash_str_new(const char *info);
GHash *BLI_ghash_int_new(const char *info);
GHash *BLI_ghash_pair_new(const char *info);
Replaced almost all occurrences of BLI_ghash_new() with one of the
above functions.
- memset(..., -1) is used incorrectly even though it worked: MOD_solidify.c - thanks Halley from IRC for noticing this. use fill_vn_i() instead.
- quiet warnings in editmesh_slide.c
- cleanup comments in bmesh and some other minor comment additions.
