to exist and accessed without prior NULL checks (with exception of
get_next_frame and get_movie_path). The callbacks are not reliably
initialized however if none of the video formats is enabled (AVI being
the default). Added stub functions now that ensure access to
bMovieHandle callbacks is safe and doesn't crash.
This is done by adding a Volume Scatter node. In many cases you will want to
add together a Volume Absorption and Volume Scatter node with the same color
and density to get the expected results.
This should work with branched path tracing, mixing closures, overlapping
volumes, etc. However there's still various optimizations needed for sampling.
The main missing thing from the volume branch is the equiangular sampling for
homogeneous volumes.
The heterogeneous scattering code was arranged such that we can use a single
stratified random number for distance sampling, which gives less noise than
pseudo random numbers for each step. For volumes where the color is textured
there still seems to be something off, needs to be investigated.
* Now only middle-clip when both left and right parts of remaining strings are at least two times icon-width (thus most short labels will never be middle-clipped).
* Add a trailing ellipsis to right-clipped strings (unless it would take more than 20% of whole available width, in this case just clip chars, to keep as much data visible as possible!).
The sanity check for copying socket default value was using the socket
idname for type compatibility checks, which is too strict. Subtypes
would not be recognized as copyable, but since only the plain data type
is needed below this is all that needs to be checked.
That alone would not cause crash (just missing default value copy),
but the tree view template was messing with the default_value DNA
directly by freeing it in advance, which is not necessary and should
be left to blenkernel when freeing the node. Otherwise this would
leave the node invalid without a default_value if the copy function
bails out.
[ foo = bar ] has been the traditional compare operator, using == is supported by some shells, but not all. The latter offers no advantage over the former.
Differential Revision: https://developer.blender.org/D179
In separating out the adj mesh change from a profile change,
I'd forgotten that some profiles need to be flat (in particular,
for vertex-only bevels). This fixes that.
This gets rid of a hacky way of setting the mesh
coordinates at corners, which created overlaps
in some cases.
Also, special case a cube-like corner with all
edges beveled, to snap to a sphere, giving more
expected curvature in that case.
Originally by Dan Eicher, with my own fixes and adjustments (see patch page for details).
For details there are unit tests and api example usage.
