  1. Thanks for sharing this tutorial! Really learned about vector filed.

    The question is, how we could add the particle information to shader, so that in each part of the pipe, the particles remain the same color?

    Thanks in advance.

  2. Great video.
    Question for you: I have curve data that is output from a simulation that includes the velocity information. On a small sample of the data, I can reproduce the results of the video with some small modifications. I can’t use the same technique on the full data as the size of the VDB needed blows the memory out of my machine (in order to capture the fine detail in the flow, the VDB voxels are really tiny). In the video you mentioned that you could do a lookup of the velocity. I’ve tried using a POP VOP with xyzdist to find the nearest velocity, but it doesn’t seem to work.

    Any ideas?
