calls
which resolves some possible issues with operating files with quotes and backslashes.
Also this might resolve (or at least help) resolving compilation error on GNU Hurd platform
which will help a lot maintaining Blender for Debian.

Vector.angle_signed(other)
for 2D vectors to get the clockwise angle between them.
in BLI math its called - angle_signed_v2v2()
shorthand for...
atan2f((v1[1] * v2[0]) - (v1[0] * v2[1]), dot_v2v2(v1, v2))
also corrects compile error in last commit.

the problem was numeric precision when in ortho mode the start/end points for the view vector would be 2000 apart which caused trouble for the intersection test.

faces.
No functional changes, this is just a bit easier to read I think (and
nicer if we add more PBVH types in the future, e.g. for dynamic
topology sculpting.)

quads.
|
|
problem was bow-tie quads would add opposite normals together and result in zero vector which was used for projection.
Now is_quad_convex_v3() checks if quad contains 2 faces which point away from eachother when split by either direction.
Theres another fix for this bug which can be done since creating the face can use existing edges in the example given so it wont have to guess which order of verts to use.

BLI_utildefines.h, giving compile error.

- edgebisect bmesh operator used uninialized beauty field.
- BLI_join_dirfile could read from before the string bounds when passed an empty dir string.
- pransform could use an uninitialized projected coordinate (unlikely but possible)
- RNA_property_path_from_ID_check would compare against an uninitialized pointer when the path wasn't found.
also have bmesh walker use BM_edge_other_vert() utility function.

from Jason van Gumster (thefallenweeble)
adds render_complete and render_cancel callbacks to bpy.app.handlers
|
|
|
|
|
|
funcs.
added copy float/double funcs: copy_v3fl_v3db(), copy_v3db_v3fl(). 2d & 4d too.
|
|
also remove large, duplicate comments from sunsky.h
|
|
Issue was caused by precision errors with floats.
Made internal grid drawing stuff using doubles and also added some
functions to multiply double vector by float matrix which also makes
all intermediate calculation in doubles.

position.
|
|
console (all had duplicate code).
this is also a step toward the console working with utf8 though many todo's remain.
|
|
|
|
There are still fairly bewildering set of callbacks being tossed
around, but it's at least a little less verbose now.

Previously, the shading and material was set once per PBVHNode when
drawing. This is still the case, but PBVHNodes are now built to
contain only one material and shading mode.
This is done with an extra partitioning step; once the number of
primitives in the node falls below the PBVH leaf limit, it's
primitives are checked for matching materials. If more than one
material or shading mode is present in the node, it is split and
partitioned (partitioned by material rather than 3D location.)
Given a sufficiently 'annoying' input, like a dense mesh with
thousands of materials randomly scattered across it, this could
greatly increase PBVH build time (since nodes might end up containing
a single primitive), but in general this shouldn't come up.
In order to support materials for grids, the CCGDM is building another
grid array (of DMFaceMat structs). This could be used to replace
CCGDM.faceFlag for some small memory savings (TODO).

Remove the function (and call to) check_partitioning(), this was just
a debug function.
|
|
Removes also a confusing else{} block that didn't make much sense.

* add BLI_rfindlink for reverse index lookup (used so bm.select_history[-1] doesn't have to loop the entire list twice).
* add bm.select_history.active so you can get the last selected item or None without having to check seq length.
|

|
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
|

for bevel.
|
|
added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count
|
|
The new functions are copy_v2_fl, copy_v3_fl, and copy_v4_fl.
|
|
where the values are unchanged.
|
|
also have doxygen ignore *.py files and fix some warnings.
