Own bug from rBc691551249f3. Now at least I understand why `test_index_face()` is needed for tessellated quads!
Added a bunch of comments to explain the issue, as it's far from an obvious one...
We loose some performances, but it's still much quicker than org code.

to tessellate).
The main idea is to store (during tessellation) or recreate (during tessdata update) a tessfaceverts-to-loops mapping, and then update all tessdata
in one pass, instead of calling `BKE_mesh_loops_to_mface_corners` repeatedly for all tfaces!

This simply mimics code used for loopnormals, to enable py scripts to generate and access (temporary)
a tangent 3D vector and bitangent sign for each loop. Together with the split normals, this allow
to recreate a complete tangent space for normal mapping (bitangent = bitangent_sign * cross(normal, tangent)).
Expects all faces to be tri or quads.

rename change/is_change/is_changed/modified -> changed
also use bools over int/short/char and once accidental float.

My previous fix for uninitialized texture coordinates was not working well,
and in fact there was a bigger issue with GLSL drawing and missing attributes
with immediate draw mode. Now it will explicitly pass zero rather than having
it use whatever value was set last.

Move static variables to context filling in by this fcuntion
and owned by a callee function. This ensures no conflicts
between threads happens because of static variables used in
this function.
Also moved modifier types and virtual modifiers data to a
function called from creator. This is needed to be sure all
the information is properly initialied to the time when
threads starts to use this data.

In the case where the modifier stack didnt need deform-verts to calculate,
they would not be available for the preview either.
This fixes a bug caused by r57206 which set mirror to preview so the mirrored
weights would be displayed, but it only worked when there was an armature after it, see [#35545].

If multires has got zero subdivisions in sculpt mode, no need
of displaying warning message. It was rather strange decision
which confused artists.
Now multires with zero subdivisions will be ignored silently
when in sculpt mode.

also correct recely added asserts.

but its not needed.
Now add asserts to make sure this layer is only added once the modifier stack has been calculated.
this saves normal layer being calculated whenver vertex normals need updating.
|

many modifiers were calculating normals, when those normals were ignored by the next modifier.
now flag normals as dirty and recalculate for modifiers that set use `dependsOnNormals()` callback.
Quick test on mesh with 12 modifiers (mostly build type), calculated normals 6 times, now it only runs once - so this will give some speedup too.

On file save the mesh gets loads from the editmesh but the derived mesh caches
wer not cleared. This usually happens through the depsgraph but it needs to be
done manually here. Most changes are some refactoring to deduplicate derived
mesh freeing code.

Made it so dynamic topology will flush changes from
SculptSession->bm to Object->me.
Used the same approach as sculptsession_bm_to_me does,
but instead of using DAG_id_tag_update used in-place
DerivedMesh release. Otherwise this lead to some
update issues resulting in missed object after render.
Also fixed multires modifier not being applied for
render when rendering from dyntopo sculpt mode.
P.S. Apparently sculpsession_bm_to_me was declared
in BKE_paint.h but implemented in object.c.
Rather confusing and better make it so this
functions are declared and implemented in
consistent files. But will solve this in a
separate commit.

correct even though in this case the error was harmless.

A previous bugfix disabled the dynamic paint modifier for orco texture
coordinate evaluation of the modifier stack. However the MOD_APPLY_USECACHE
flag is not a good way to check if the modifier is evaluated for orcos.
Instead I've added a MOD_APPLY_ORCO flag. Also removed a bunch of
applyModifierEM callbacks, none of them served a purpose except for the
subsurf modifier.
