Cycles: Add option to split curve motion primitives by time steps The idea is to create several smaller BVH nodes for each of the motion curve primitives. This acts as a forced spatial split for the single primitive. This gives up render time speedup of motion blurred hair in the cost of extra memory usage. The numbers goes as: BVH Steps Render time (sec) Memory usage (MB) 0 258 191 1 123 278 2 69 453 3 43 627 Scene used for the tests is the agent's hair from one of the barber shop scenes. Currently it's only limited to scenes without spatial split enabled, since the spatial split builder requires some changes to work properly with motion steps coordinates. |
