Not all three sides of a tesselated mesh triangle are guaranteed
to be original mesh edges, so a somewhat complicated check is
required to detect which ones are real. It seems that until now
there was no utility function for that, only some example code.
|
|
Loop triangles are tessellated triangles create from polygons, for renderers
or exporters that need to match Blender's polygon tesselation exactly. These
are a read-only runtime cache.
Tessfaces are a legacy data structure from before Blender supported n-gons,
and were already mostly removed from the C code.
Details on porting code to loop triangles is in the release notes.

Some sort of rudiment from many years ago, is never set by 2.5x code.

For real guys! Test your example code!

Convention was only followed loosely,
apply to DNA where changes aren't likely to conflict.
(Skipped ModifierType for eg).
|
|
- MTexPoly structure & layer type.
- The 'Mesh.uv_textures' layers.
- DerivedMesh TexFace drawing.
- Scripts & UI.
|
|
- Derived-mesh drawing.
- All non UV members of TexFace structs.
MTexPoly is now redundant but keeping with a dummy member,
will check on complete removal later.
|
|
TexFace complicates the now more popular shading pipeline by having
per-face images, see: T51382 for details.
To keep the ability to select a per-material edit-image
(used with UV-mapping workflow), the material now stores an image
which will be set when changing images in edit-mode.
This is used as a bake-target when not using Cycles too.

Note that the collision modifier doesn't have any use for Loop indices,
so to avoid duplicating the loop array too,
MVertTri has been added which simply stores vertex indices (runtime only).
|
|
This stores loop indices into the loop array giving easier acess
to data such as vertex-colors and UV's,
removing the need to store an MFace duplicate of custom-data.
This doesn't yet move all internal code from MFace to LoopTri just yet.
Only applies to:
- opengl drawing
- sculpting (pbvh)
- vertex/weight paint
Thanks to @psy-fi for review, fixes and improvements to drawing!

Deprecated Freestyle-specific elements were removed from the code base,
in order to address all comments from branch code reviews.
https://codereview.appspot.com/7416049/
Backward compatibility won't be maintained in the following components:
- Freestyle edge/face marks in old .blend files are ignored.
Old .blend files can be converted by loading and saving the files using
a Freestyle branch build between revision 55581 and 55842.
- External style modules are no longer supported.
Instead text datablocks must be used to keep style module files within
.blend files. A branch build between revision 55741 and 55842 is useful
for identifying the style module file names that need reconfiguring.

and RNA for it independent of the build flag for enabling Freestyle. Suggested
by Sergey Sharybin through a code review of the branch.
* Many #ifdef WITH_FREESTYLE blocks were removed to always have Freestyle-specific
DNA file specification and RNA for it built in Blender. This will allow Freestyle
setting survive even when a non-Freestyle build is used for loading and saving
files. It is noted that operations are still conditionally built through #ifdef
WITH_FREESTYLE blocks.
* To this end, new blenkernel files BKE_freestyle.h and intern/freestyle.c have
been added. All API functions in FRS_freestyle_config.h as well as some of those
in FRS_freestyle.h were moved to the new files. Now the relocated API functions
have BKE_ prefix instead of FRS_.

The previous implementation of Freestyle edge/face marks was refactored
based on suggestions from the latest code review by Campbell. The new
implementation relies on mesh CustomData to store edge/face marks, instead
of introducing extra flags in the core Mesh and BMesh data structures.
The CustomData-based implementation will allow further additions of new
edge/face attributes because of the independence from Mesh/BMesh.
This revision is work in progress, mainly intended to address the review
comments and ask for further code review in view of the trunk merger in
the upcoming 2.67 release.

Caused by my assumption that alpha wasn't used for vertex colors.
Infact it is used by blender-internal rendering, but typically only for blending strand particles.
Updated comments to note this.

bmesh access allows zero bytes, support still needs adding via RNA.

Also addressed code inconsistency due to changes in the trunk revision 50628 (color
management with OCIO) and 50806 (UV project material). OCIO-related changes are marked
OCIO_TODO as in some other files modified in revision 50628.

This is an intended feature but works too unreliably.
- This setting was stored in each face and only editable by re-running the unwrap, this is too hidden (only discovered this by reading code).
- This worked with blender internal but not with cycles, such basic options as changing an image shouldn't behave different depending on the render engine selected.
I've ifdef'd out the aspect correction for now, it could be added back as a per scene option and be made to run on both cycles or blender internal but for now I prefer to keep this disabled.

unwrapper flush the correct aspect flag to mtpoly after unwrap. Faces
that have been unwrapped with correct aspect option will fix their
aspect each time a different image is assigned to them. I hope fix works
100%, I can't say that I really understood the bizarre aspect ratio
system.

The MVertSkin currently just stores local skin radii and skin
