Color ramp with constant interpolation must bypass texture filtering and
use nearest neighboor sampling in order to appear correctly sharp.
This patch use a GLSL hack to use nearest sampling on thoses particular
color band.
This lower the use of texture samplers slots and let users use more real
textures in their shaders.
This patch also make the ramp texture 16 bit floating point. Meaning you
can now use value greater than one in your color ramps.
With the limit of 128 colorband per shader (a color band being either a
color ramp, a wavelength node or a curve node (and maybe wavelength node in
the future)).
Only drawback with the current implementation is that it does not remove
colorband from pruned GPUNodes but it shouldn't really matter in practice.
This should fix T56010
This is a rough (but fast) approximation that still match cycles reference
in common case.
In practice, it's just adding more of the diffuse light computed for the
diffuse contribution.
As grease pencil use multiedit frames instead of multiobject edit, this fix solves the issue.
In the future maybe will need modifications if we add multiobject support, but we need a solution now.
This is more like a static optimisation when some parameters are set to 1.0
or 0.0. In theses case we use a more optimized version of the node.
This also revisit the transmission parameter behaviour to make it closer to
cycles.
This was likely caused by some sort of race condition where the drawing
thread would request the state of the shader before the shader has been
compiled.
Thanks to Charlie Jolly (mistajolly@gmail.com) for his patch D3586 that added create materials to opacity modifier.
I had to do some more changes to get all running.
Patch porting to OpenJPEG 2.3 is by Campbell.
Once all platforms are upgraded we can remove the code for 1.5, and upgrade
or remove the openjpeg version from extern/. This intermediate step makes it
possible for platform maintainers to upgrade to 2.3 without breaking other
platforms.
This memory leak was undetected during a long time, but with new memory checking is visible.
The problem was the stroke buffer batch was realocating new batches without free the memory.
new background image/clip of Camera ID was totally wrong, down the old,
broken 'way it used to be' instead of using new, more generic system.
Those ID pointers were not even added to library_query.c file, shame! xD
