In some heavy rigs matrix inverse can be 10% of computation time. This
reduces it to 2% by using Eigen's optimized 4x4 matrix inverse and SSE
matrix multiplication.
- Uses the roughness setting of the basic eevee material
- renamed gloss_mir to roughness
- set default of roughness to 0.25
- renamed ray_mirror to metallic
- cleaned up material rna (BI mirror struct)
- use BLINN phong model
- normalize incoming/outgoing specular light
- when using camera oriented studiolight, the SolidLight will be used
for specular highlights
- EXPERIMENT: when in world oriented studiolight only the shadow direction will be used.
- change the settings of the internal light to make scenes more
readable
Note there is some talk about changing the position of this (which would be strange in the image editor by the way,
since there we use the bottom for the result of the current pixel when dragging the mouse).
However first I wanted to fix this regardless.
This currently shows panels that were in the 2.79 3D view toolbar
which are now popovers.
In some cases it's useful for these to stay open.
This commit adds a space type to do this.
Note this is currently empty in object mode.
This overlay is showing mesh topology. It is usable with transparency
even if the mesh order can mess up with the expected result (some object
more prominent than others).
Edge thickness and alpha values are hardcoded for now but can easily be
added to theme or object settings.
Only OB_MESH is supported for now.
Creates a simple index buffer with negative indices if the edges is not a
real edge.
Also create the buffer texture representation of this buffer along with the
pos_in_order buffer texture.
This includes:
- Skip OB_RECALC_TIME tag from object duplicate operator
not sure why it is needed: even if original object was
animated, duplicating it will copy evaluated values.
- Don't tag whole ID for update when updating it after
relations rebuilt. Use the same trickery to detect
whether animation is to be re-evaluated or not as is
done for update flag=0.
- Don't tag datablocks which are expanded for update
of copy-on-write.
- Avoid flush along relation from copy-on-write
operation in action. This will not invalidate any
pointers in the copied datablock since we don't
reference anything in the action.
Will cause some bad behavior when object is shared across multiple
visible view layers with different overrides. Accept it for now,
and possibly force single view layer later.
When active dependency graph is evaluated, it will apply animation,
drivers and scalar evaluation data (such as object matrix) to an
original datablock. This way operators and tools can easily read
data from original datablock.
This will simplify porting them to copy-on-write, and solve issues
when some operator will allocate new datablock based on original one,
and will want to read data from it.
This way we allow animation system to make decisions based on which
context dependency graph is coming from, and whether it belongs to
an active edit window or not.
