81b32e88a3 BMesh: add BKE_bmbvh_find_face_closest 2015-12-14 00:16:05 +11:00
59e166c568 BVH-raycast: Use watertight intersections
By default watertight intersections are used,
For callbacks where its not needed,
BLI_bvhtree_ray_cast_ex can be called without the BVH_RAYCAST_WATERTIGHT flag.

Fixes T45286

a2a7260915 BMesh: option to filter out faces during raycast
This allows us to more easily cast from the surface of a mesh
without normal offsets (Which can give precision issues).

4ca67869cc Code cleanup: remove unused includes
Opted to keep includes if they are used indirectly (even if removing is possible).

238d2f962d BMesh Refactor: BKE_bmbvh_new can now be created without an EditMesh.
This adds BM_bmesh_calc_tessellation() so we can get triangles from a
bmesh without having to have an editmesh available.

86f8470a5d Some knife fixes. Avoids duplicating verts; better handling of cut-through ortho.
Now cut lines detect vertices that they pass (almost) exactly over
and snap to them, to avoid making verts vert close to other ones.

Added radius arg to BKE_bmbvh_ray_cast so that can detect an obscuring
face when the ray might otherwise go exactly between two triangles.
Needed an isect_line_tri_epsilon function for similar reason.

Fixes last part of bug #35002. Other knife bugs still present but
getting this commit in now before continuing bug fixing.

c33093ac08 BKE_bmbvh_find_vert_closest: very stupid & old bug, it was comparing hit locations incorrectly so that only the first hit was valid.
This isn't noticeable for small distances, otherwise it gives bad results.
2013-06-19 20:43:38 +00:00
93af050824 correct editmesh BKE_bmbvh_find_vert_closest(), distances are expected to be squared. 2013-06-19 20:11:28 +00:00
6db3375e4f code cleanup: removed unneeded null check in object drawing, some warnings, style. 2013-04-18 15:09:30 +00:00
8a06acfd7a add mesh distort display mode (highlights distorted faces) 2013-04-18 04:24:18 +00:00
e7895abb32 make bmbvh call BM_mesh_elem_index_ensure(), further calls to utility functions assert if the index values becomes dirty. 2013-04-18 02:01:59 +00:00
9cceec40c4 use modified vertex coords for calculating display thickness and intersections.
internal improvement to editmesh_bvh.c

- optionally pass cage-coords as an arg, rather then calculating the coords in BKE_bmbvh_new(),
  since all callers already have coords calculated.
- de-duplicate coords creation function from knife and bmbvhm, move into own generic function: BKE_editmesh_vertexCos_get()
2013-04-18 01:20:04 +00:00
2fefbf24a5 bmbvh was allocating an array for vert coords but not using it, removed.
also use generic name for callback data.

67034c378d fix for BMBVH_USE_CAGE option,
knife tool with modifier was broken when modifier cage was used.
2013-04-18 00:19:57 +00:00
cfefa1d086 add function BKE_bmbvh_find_face_segment()
given a segment, finds finds an intersecting faces from the first point to the second, needed for checking self intersections (not used yet).

861a38ea09 code cleanup: bmesh bvh
- remove unused members from BMBVHTree
- move per-raycast vars from BMBVHTree into per-callback structs (weren't threadsafe).
- simplify BKE_bmbvh_find_vert_closest().
2013-04-17 06:18:21 +00:00
b0752f1b89 add interp_v3_v3v3v3_uv() to use for use with uv value from isect_ray_tri_v3(), rename tree -> bmtree for BMBVHTree. 2013-04-17 05:49:06 +00:00
c458e051d3 fix for BKE_bmbvh_ray_cast() returning one of the vertices normals rather then the face normal. also remove redundant NULL checks. 2013-04-16 15:35:01 +00:00
9f5006a967 add distance arg to BKE_bmbvh_ray_cast(). currently unused. 2013-04-16 15:16:48 +00:00
ea0ad013d3 bmesh speedup for bvh building, replace SmallHash with BLI_bitmap, using a hash doesn't make much sense since in most cases all vertices are accessed and the hash isn't guaranteed to be small.
gives ~9x speedup to filling 'cagecos' in my own tests on a high poly mesh.
2013-04-16 14:57:02 +00:00
fe4305ef82 skip calling BKE_editmesh_tessface_calc() from BKE_bmbvh_new(), also quiet float/double warnings. 2013-04-16 13:01:46 +00:00
c429349054 Fixed compilation error with gcc 4.4 and 4.5
Was giving structure re-declaration error,
made it one typedef and struct declaration only.

37e73aa368 code cleanup: use BKE naming conventions for functions in BKE_editmesh.h and BKE_editmesh_bvh.h 2013-04-16 05:59:48 +00:00
77da6b3662 move editmesh functions out editderivedmesh.c into editmesh.c 2013-04-16 05:46:17 +00:00
