HoudiniEngineForMayaで読み込んでみるとこんな感じに見えます。 Recently I found an interesting problem while trying to convert Houdini dense (native) SDF volume into a VDB SDF volume. Tutorial Assets Andy, the O(N) thing got me thinking and realized that instead of running the attrib wrangle in detail mode, which uses only a single thread, it'd be possible to generate say 4 points and, in a point wrangle, let each of these points process 1/4th of the array, thus effectively running the same logic on 4 threads! Houdini OpenGL viewport has its limits and cannot visualize big volumes with a small voxel size. Fluid simulation: collision reversed ? Use a vdb with a static solver, and reverse the vdb with a volume wrangle @surface *= -1; Why is my motion blur not working ? You need 'v' and to check 'geometry velocity blur' on your object The input of the Volume sop is Bounding Source. Technical Note Houdini (houdini) VEX Code. In our case, Volume Wrangle , the loop will iterate over all the voxels. If you emit particles and advect their position by the velocity of your volume, then you can use the Trail SOP to retrieve the position of each particle at each frame up to say 5 frames before, which will give you 5 points for each particle that you only need to connect together For Houdini tutorials in general, on the non commercial side, Peter Quint has a very comprehensive set on Vimeo covering various techniques.
