8 years ago Hmm I have some ideas for opt flow...
- Make 2D vector field grid from optical flow then put particle which moved by vector in each grid cell => the particle will be the brush
- Use fluid lib like ofxFluid => the fluid tex could be the brush
If you would like to use some motion with this addon, I think obj tracking is more feasible than opt flow, because we can use the contour as brush directly. I have used this addon with kinect & cv & fish, that was successfull to some extent.

Hi! I wonder if you could suggest how to approach the flow driven brush project. Instead of mouse drawing, I would like the brushes to be moved programmatically by optical flow.
I have a gpu optical flow implementation, and now would like to use the resulting motion texture in succeeding shaders to take the color of the source texture and apply it to the optical movement.
Do you think it would be hard to plug the optical motion and the color source textures into your approach to replace the generative brushes and their movement?
Thanks.
