- Fix a comparison bug in VHACD Volume::Voxelize causing the number of voxels to explode when x == y and z < x. - Activate axis alignment in VHACD to fix huge voxels being created due to an elongated part being placed diagonally in the voxel space causing precision problems. - Make the data ordering in vhacdVolume GetVoxel more cache friendly toward loops iterating over (i,j,k) in that order. - Parallelize bulk convex hull computation and make it available in blueprint. - Replace standard allocator with our own (TBB) so that the parallel code actually runs faster instead of locking on allocs. - Add an overridable task runner interface in VHACD to reuse our task pool instead of spawning threads for each async task. - Add an overridable profiler interface in VHACD so we can add Insights tags inside VHACD. - Fix convex hull computation progress not being shown when run inside a dataprep operation. - Rewrite voxel flood fill algorithm toward cache friendliness and get rid of extra data structure causing high memory usage on large voxels. - Recompile VHACD using clang/llvm Results for running a generic convex hull dataprep operation on all meshes - 305m @ 20GB RAM -> 2m25s @ 6GB RAM on 7628 meshes (DATASET-0019a) - 486m @ 49GB RAM -> 3m33s @ 9GB RAM on 5506 meshes (DATASET-0008a) Tested on Windows/Mac/Linux From dev-enterprise@11497987 #jira UEENT-3026 #rb Benn.Gallagher, Julien.St-Jean [CL 11499409 by danny couture in 4.25 branch]
