7 years agoFix T39547: Toggling render passes on active scene does not update

Fix T39547: Toggling render passes on active scene does not update
render layer nodes in a pinned tree from different scene.

The way these updates work is a nasty legacy hack:
https://developer.blender.org/diffusion/B/browse/master/source/blender/nodes/composite/node_composite_tree.c$277

This function is called //very frequently// by the get_from_context
method. However, this does not get called for pinned node trees, so
when showing a different scene's compositing nodes in the editor they
may not get updated correctly.

Now moved this update call out of get_from_context so it happens in any
case. Will be called no more frequently than before (on every redraw).
Eventually the depsgraph should handle this more precisely, it's just a
simple ID dependency anyway ...

Make matcaps suck less

This commit does various changes for matcaps:

One is taking advantage of drawing with pbvh (which would only happen
with dyntopo previously) and drawing with partial redraw during
sculpting.

The second one is support for masks. To make this work in the special
case of multires, which uses flat shading, I use the only available flat
shaded builtins in OpenGL 2.0 which are color and secondary color.

Abusing colors in that way is also essential for flat shading to work if
we are to use pbvh draw in multires, since it is the color that is being
interpolated flatly, not the normal (which can only interpolated
smoothly). The pbvh drawing code for multires used last triangle
element's normal to compute the shading which would only produce smooth
results. This could change if we did the shading in the vertex shader
for flat shaded primitives, but this is more complex and makes it harder
to have one shader to rule the mole.

Also increased the brightness of the default diffuse color for
sculpting. This should be useful since artists like to tweak the
lighting settings and it will give them the full dynamic range of the
lights, but also it helps with correct brightness of sculpted matcaps.

Cycles volume: change heterogeneous volume sampling in branched path first hit.

This now uses decoupled ray marching, and removes the probalistic scattering.
What this means is that each AA sample will be slower but contain less noise,
hopefully giving less render time to reach the same noise levels.

For those following along, there's still a bunch of volume sampling improvements
to do: all-light sampling, multiple importance sampling, transmittance threshold,
better indirect light handling, multiple scatter approximation.
