- update to version 3.12.0
+ Added linear cone curve geometry support. In this mode a real
geometric surface for curves
+ with linear basis is rendered using capped cones. They are
discontinuous at edge boundaries.
+ Enabled fast two level builder for instances when low quality
build is requested.
+ Bugfix for BVH build when geometries got disabled.
+ Added EMBREE_BACKFACE_CULLING_CURVES cmake option. This allows
for a cheaper round
+ linear curve intersection when correct internal tracking and
back hits are not required.
+ The new cmake option defaults to OFF.
+ User geometries with invalid bounds with lower>upper in some
dimension will be ignored.
+ Increased robustness for grid interpolation code and fixed
returned out of range u/v
+ coordinates for grid primitive.
+ Fixed handling of motion blur time range for sphere, discs, and
oriented disc geometries.
+ Fixed missing model data in releases.
+ Ensure compatibility to newer versions of oneTBB.
+ Motion blur BVH nodes no longer store NaN values.
