i was wondering if fathom (or kinect) captures random points for each frame or captures points initially which then get tracked and moved around, keeping the IDs of each particle?
Also wondering if the imported particles have velocity data.
If they dont but keep the correct IDs from one position to the next in each frame, I have a box3 operator which calculates the velocity based on two positions, might be useful, but this wont work if they are randomly assigned each frame.
Fathom doesn’t currently have any way to track points and assign a velocity. Instead of tracking points, it gets the depth of points in a 2d grid. However that seems pretty useful, so I’ll put it on our wish list.
The Kinect does have built-in skeleton tracking, so you could, for example, find the velocity of your elbow.
nice,
would there be any way you could think of for me to generate some velocities with the way it works right now?
just want to see if i can spawn other particles off it *which require velocities, or do some fume advection which also require velocity
