ideally these would be used as generated coordinates, but this is tricly because cycles calculates its own orco's and doesnt know about curve settings.
Refactored code a bit to make naming a bit more clear and added a
function to create mesh from given display list rather than from
object's displist.
Tested using plain curves (which doesn't imply using derived meshes)
and curves with constructive modifiers (which are using derived meshed).
Added back face validation to BKE_mesh_validate_arrays.
This is needed because some addons (like OBJ importer) are reading
tessfaces and then converting them to ngons and validation of tessfaces
is needed before such a conversion.
Validation of faces would happen only if there's no polys in mesh.
Issue was caused by do_versions being used pdata as reference for active/render/
stencil/clone layer indices instead of fdata.
Added some utility functions used only by do_versions to be sure this indices
are set from fdata for pre-bmesh files.
The issue was caused by CDDM_tessfaces_to_faces not dealing with CD layers.
There was already function BKE_mesh_convert_mfaces_to_mpolys which converted
mfaces to mpolys with converting all CD layers. Made it a bit more general so
it might work with given arrays of faces/polys and re-used it from CDDM module.
Checked with UV and sculpt data from Blender 2.61 and it loaded nice, so
hopefully there's no regressions in loading older files.
/* Return the index of the edge vert that is not equal to 'v'. If
* neither edge vertex is equal to 'v', returns -1. */
int BKE_mesh_edge_other_vert(const struct MEdge *e, int v);
Should also fix [#30266], [#29451], and partly [#30316].
Here are the changes made by this commit:
* It adds a "dirty" flag to DerivedMesh struct (for now, only DM_DIRTY_TESS_CDLAYERS, but more might be added as needed).
* It adds a new func, DM_update_tessface_data, which assumes tessfaces themselves are valid, but updates tessellated customdata from their poly/loop counter parts.
* At end of modstack, when valid tessellated faces are present in finaldm , but the cdlayers dirty flag is set, call that function (instead of recomputing the whole tessellation).
* Edits to the codes concerned (UVProject, DynamicPaint, and Subsurf modifiers).
* Also add to subsurf dm generation code the creation of a CD_POLYINDEX layer (mandatory for DM_update_tessface_data to work well, and imho all tessellated dm should have one).
Note: some pieces of old code are just #if 0’ed, will clean them later.
Changed the create_vert_poly_map function to return a more compact
structure. Memory saved will vary depending on the mesh, but typically
it should be about one third of the old size.
Everything seems to work well (many tests making random changes over various meshes went good), but the code is a bit complex and hard to follow, due to the various possibilities of invalid poly/loop combinations… Code also makes more operations than previous tri/quad faces version (hence is a bit slower), but I don’t think we can do otherwise, it’s just the price for bmesh flexibility. ;)
Note: added the py script I used to make the tests, under source/tests/...
- 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.
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
this commit makes vertex paint check if it needs to rebuild the modifier stack when painting.
- when painting with no modifiers, do partial updates from polys to tessfaces while painting, skip re-tesselation.
- when painting onto a modified mesh, dont bother adjusting tessface colors - since the modifier stack will do this anyway.
both cases should be faster then before.
Next, uv sculpting will be ported.
Also fixed "initializer element is not computable at load time" compile error caused due to bit-shifting a constant past its precision length (1L should be 1LL for 32 positions left shift).
=========================
Documentation: http://wiki.blender.org/index.php/User:Psy-Fi/UV_Tools
Major features include:
*16 bit image support in viewport
*Subsurf aware unwrapping
*Smart Stitch(snap/rotate islands, preview, middlepoint/endpoint stitching)
*Seams from islands tool (marks seams and sharp, depending on settings)
*Uv Sculpting(Grab/Pinch/Rotate)
All tools are complete apart from stitching that is considered stable but with an extra edge mode under development(will be in soc-2011-onion-uv-tools).
* CDDM_calc_normals
* CDDM_calc_normals_tessface
these match what we have in trunk - CDDM_calc_normals_mapping() is kept for more comprehensive operatons.
comparing bmesh to trunk, mesh_calc_normals() in bmesh is a much more comprehensive function, calculating mpoly,mface normals, where trunk only calculated vertex normals.
renamed:
* mesh_calc_normals() --> mesh_calc_normals_mapping_ex
* mesh_calc_tessface_normals --> mesh_calc_normals_tessface() - only calculates normals from tessface
* added mesh_calc_normals() - only calculates normals from poltys
this way we can have mesh_calc_normals() remain fast for parts of the code which only need vertex normals to be updated.
only refactor, no func changes- didnt replace mesh_calc_normals_mapping_ex() with mesh_calc_normals() anywhere yet.
