the iterator initialization function.

convex_hull at the moment.

Notes:
*This implements a quite simple algorithm, which simply checks angles (actually, absolute cosines) of created tri and remaining face (which may be a tri, quad, or more NGon), so that both are "best" (ie avoid as much as possible too much narrow/wide corners), and also checks the new edge is OK (i.e. does not goes "out" of original face).
*Incidently, it fixes a typo in that bm_face_goodline() func!
*It's quite performant (a bit quicker than previous code, as far as I have tested it) and prevent creation of completely flat triangles as much as possible, but it's far from being a "best" solution (as it is still a "progressive" one)!
*It also introduces a new math func (in BLI_math_vector.h), cos_v3v3v3, which computes cosine (ie dot product of normalized vectors) and is roughly a quicker replacement for angle_v3v3v3, when real angles are not needed.

from Benoit Donat-Bouillud (ladeheria)
from tracker -
When using a screw axis (reference edge for screw), the operation always give the same result (as if the orientation of the reference edge was not take into account).

Add check for merging vertices into vertices that are themselves
marked for merge, was already done for array eleements but not end
caps.
Fixes bug [#31695] Array Modifier: End Cap fails if all vertices are merged
Also corrected some reversed assert arguments.

style and remove BM_face_find_longest/shortest_edge functions,
... instead use BM_face_find_longest/shortest_loop()->e
|
|
initializations.
|
|
|
|
also small speedup for finding the longest edge

destination and source in copy function. Also fixed an error in Py API, check to see if layers were different should be check to see if they're the same.

bmesh regression where the edge-draw flag was cleared when bmesh modifiers were used.
|
|
BM_edge_loop_pair returned TRUE for single face user edges.

- style - multi-line ifs move braces onto new lines.
- iterators - convert some to macros, other split up and move brace.
|
|
replace do prefix with do_ for bool vars.

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.

Change hull's point/triangle side test to > rather than >=.
This seems to fix the (infinite?) loop, but not the crash.
|
|
Keep track of interior verts during the hull build to avoid
imprecise floating-point test afterward.
|
|
- use bmesh iterator macros in more places
- rename scanfill variables (were using same names as mesh faces/verts which was confusing)
|
|
vector function edits.
|
|
|
|
- use angle_normalized_v3v3() where both vectors are known to be normalized.
- remove needless radian to degrees conversions.
- move checks for customdata layers outside the inner loop (for bevel and crease).

vertex dissolve would skip dissolving some verts that should be dissolved).
now do this:
- edge dissolve
- cleanup (removing edges left over from dissolving faces)
cleanup removes verts and NULL vertex input array
- dissolve verts which haven't been removed.
|
|
bad bug where vertices could be in a face more then once (which isn't allowed), now check for this when creating a face.
|
|
|
|
|
|
this is in fact 2 bugs.
- unselected edges between 2 faces that were joined didnt get removed.
- in face mode, edges and verts at the boundary of the selection would get incorrectly dissolved.
also quiet float/double promotion warning.

previously
it would displace in all directions. Now there's an operator option to control this.
|
|
|
|
also quiet unused var warnings
|
|
|
|
currently checks for brace placement and some whitespace use.
can be accessed with:
make test_style
or...
source/tools/check_style_c.py source/blender
also style cleanup on bmo_primitives.c

disk_links of edges, so wasn’t working at all with edges remapping!

- bm.*.layers.*.verify()
- bm.*.layers.*.is_singleton
- bm.*.layers.*.copy_from(other)
also added api functons
- BM_data_layer_copy(...)
- CustomData_layertype_is_singleton(type)
