Color Smoke
The Color Smoke effect I did for studying the micro solver in Houdini DOP network. I want to learn how to manipulate the date inside the DOP network to create the custom smoke simulation I want.
I used Gas Match Field node to create color volume field according to velocity field. From the imported colored point cloud, I copy the color from points to the smoke volume only on first two frames( otherwise it will copy and overwrite the color throughout the simulation), then I advected the smoke color field according to velocity field using Gas Advect Field.
Color corrected in After Effects, in the later frames of the simulation, the color are getting washed out because when they are adding together, the vector values are approaching (1,1,1). Currenly developing a method to saturate the colors as they are blending together in DOP using Gas Field VOP.
