NOTE: There is a float imprecision near the focus plane
due to the current technique used for DOF. This makes the alpha channel
transparent on nearly in focus objects even when they should not.
This artifact should be fixed when the DOF will use scatter as gather for
low brightness areas.
Fix T57042 : Eevee does not render alpha when DOF is turned on
There were a few copies of the same few lines in depsgraph build code,
so it seems to be logical to introduce a function for it, and make it
accessible from C code for completeness.
As an example, register the mask needs of the Data Transfer modifier.
On my test it's 30% faster than before.
Test case : Suzanne, subsurf lvl3, 64K tris, Edge select mode for fair
comparison.
0.95ms before optimization
0.64ms after optimization
Note that this only optimize the "nicest" display of edit mesh overlays,
not the one when rotating the view where half of the border edges are
missing.
... display vertex even when occluded.
Add back the vertex display because occluded vertex are not visible when
the triangle is almost parallel to the view.
The problem with the barycentric coord is that they are hard to work with
and their derivatives not enough precise to compute the vertex positions.
So we need to pass the vertices scree positions down to the fragment shader.
After a lot of discussion about this option (see 18f1175940) we have decided set always the order of GP layers in 2D mode (Top->Down) and remove the parameter from User Preferences screen.
Internally all works equal, but in the UI the list is inverted.
The filter buttons to reverse the list or sort alphabetically have been removed because these buttons are not logic in this context.
Fix broken behavior in case of texcoords mapping (we do need texcoords
node in all cases, then, even for UV coords...).
Use nodes by default when generating new write-allowed wrapper around a
material.
Do not try to find nodes in existing tree all the time, do it only once,
even for lazy-initialized nodes (through accessors).
Fix ugly spacing in property accessors (since it looks like some people
do not like a single 'block' with both getters, setters and prop
definition, at least use one sep line everywhere (and two sep lines to
separate properties)...
New iterator CTX_DATA_BEGIN_FOR_ID, to restrict the loop to the specified object only.
This is not super efficient, but it should be fine for now.
I will talk to other developers. A more elegant solution would be to
have something like "active_object_selected_pose_bones" in the context.
This reverts commit 178530cc50e2fb4bd3faf4fff22392a58688bed1.
Those operators are called from the UI, which only takes into
consideration the active object for the parameters and whether to call
reset, update or calculate.
We can re-revert if needs be.
