Getting a new edit-derived-bmesh was always creating a deform-vert array, even when it wasn't needed.
Since this was called on redraw, in many cases it was doing it unnecessarily.
Now pass in a custom-data mask and only fill in deform-verts when needed.
Gives noticeable drawing speedup (~10-30% here).

The purpose of the patch is to replace deprecated glShadeModel.
To decrease glShadeModel calls I've set GL_SMOOTH by default

A bit tricky, need to pass additional information about what the attribute
is and how to deal with it.
BI path stays unchanged, just to make things simplier for now.
Fixes T48555: Cycles GLSL- Incorrect Vertex Color results from Attribute node
|
|
Not replacing with some BLI_task_stuff here, tests show this is pointless
(in absolute best case - i.e. single huge mesh in scene - parallelizing here switches
from 0.8ms to 0.5ms for that piece of code - with something like 750ms per frame update...).

viewport

The title says it all actually.
Added special custom data type, because we don't know in advance
whether we're referencing UV or Color layer. Also made it so vertex
attributes are normalized.
TODO: Border render in viewport ignores the normalization of the
attribute array for some reason, will be looked into still.

Normal Map node support for GLSL mode and the internal render (multiple tangents support).
The Normal Map node is a useful node which is present in the Cycles render.
It makes it possible to use normal mapping without additional material node in a node tree.
This patch implements Normal Map node for GLSL mode and the internal render.
Previously only the active UV layer was used to calculate tangents.

Many other places weren't clearing boundbox dirty flag after calculation.

Handling `me` data here is not good idea anyway, we override it completly with data
from `tmp` (crash came from freeing already existing bb from me, while pointer still existed in tmp).
(rediscovered it while working on T47676...).
To be backported to 2.77.

More in line with our other func names handling sub-item data (mainly, tessfaces' UVs and VCol...).

no functional changes
|

Each LINES draw call is now responsible for its own line width. No need
to set it back to its 1.0 default after every draw.
This eliminates half our calls to glLineWidth , similar to last week’s
work on glPointSize.

The simplest way of handling mirroring in multi-paint is creating a
uniform symmetric selection and relying on existing symmetric weights
to direct changes to the appropriate vertex groups. This already works
if mirror bones are selected manually, and can be made easier to use
by doing it implicitly.
|
|
Since the coloring uses sum or average of the weights of all selected
groups, the weight pick tool should also use that instead of reading
the weight of the single active group that you can't see.
|
|
This condition can actually happen quite often if weight painting for
a rig that uses separate control bones, so the color shouldn't be so
bright that it's hard to look at for a significant amount of time.

LoopTri changes in 2.76 calculated all tangents as triangles,
this gave different results though in most cases it was hard to notice.
Though no bugs were reported we should keep our tangents compatible with other users of mikktspace.
|
|
|
|
Specifically, when only one bone is selected and it's not really active.
(With multiple bones on the other hand that behavior is forced on,
since multi-paint can't modify purely zero weight verts and that's important.)

It also fixes another issue (crash) related to symmetric editing.
Quite involved, we (try to!) fix complete broken logic of parts of particle code, which would use poly index
as tessface one (or vice-versa). Issue most probably goes back to BMesh integration time...
This patch mostly fixes particle editing mode:
- Adding/removing particles when using generative modifiers (like subsurf) should now work.
- Adding/removing particles with a non-tessellated mesh (i.e. one having ngons) should also mostly work.
- X-axis-mirror-editing particles over ngons does not really work, not sure why currently.
- All this in both 'modes' (with or without using modifier stack for particles).
Tech side:
- Store a deformed-only DM in particle modifier data.
- Rename existing DM to make it clear it's a final one.
- Use deformed-only DM's tessface2poly mapping to 'solve' poly/tessface mismatches.
- Make (part of) mirror-editing code able to use a DM instead of raw mesh, so that we can mirror based on final DM
when editing particles using modifier stack (mandatory, since there is no way currently to find orig tessface
from an final DM tessface index).
Note that this patch is not really nice and clean (current particles are beyond hope on this side anyway),
it's more like some urgency bandage. Whole crap needs complete rewrite anyway,
BMesh's polygons make it really hard to work with current system (and looptri would not help much here).
Also, did not test everything possibly affected by those changes, so it needs some users' testing & validation too.

We have callbacks for that, they also do some checks and help ensure things are done
correctly. Only place where this is assumed not true is blenloader (since here we
may affect refcount of library IDs as well...).

Follow up to last commit, since bugs here aren't so obvious.

Tessface CustomData layers were added multiple times when tangents were used.
This made BI crash accessing layers missing elsewhere.

Caused by an -unneeded now- fix for opensubdiv. Code caused the vertex
colors to be uninitialized. Thanks to Sergey for confirming that initial
issue is no longer a problem.

Fixes T45728
|
|
The generic tangent calculation relied on CDDM arrays which aren't available in edit-mode.
Add a tangent calculation callback, which has its own implementation for editmesh data.
|
|
Use coarse coordinates to calculate AABB which gives much better approximation
of AABB than using unity AABB size.
|
|
|
|
This actually requires some bigger work to make it fully supported but
for now at least avoid breaking shading with OpenSundiv option disabled.
|
|
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).
|

Notes:
* Code in rendering and in game engine will still convert
tangents to a tessface representation. Added code that
takes care of tangent layer only, might be removed
when BGE and rendering goes full mlooptri mode.
* Baking should work discovered some dead code while
I was working on the patch, also tangents are broken
when baking from multires (also in master), but those
are separate issues that can be fixed later.
This should fix T45491 as well

The navigation mesh functionality was broken for quite a while. This patch
contains fixes: recalculating tesselations before getting the number of
tesselation faces (it otherwise returned 0) before calculating the navmesh,
and calling `DM_ensure_tessface()` on the navmesh's `DerivedMesh` object
(which fixes visualisation in Blender). This allows one to create a new
navmesh, which also works in the BGE.
Furthermore, the patch adds several return values, and shows more error
messages when things go wrong. In several places in the navmesh creation
code, return codes weren't checked and errors silently ignored.
