Sorry if feels like double post, I longly hesitated to continue the motion vectors thread or start a new one, but since it’s quite houdini , I didn’t wanted to flood the other thread.
SO ! since Houdini 16.5 release an intriguing feature has been included, Volume Optical Flow ! I didn’t see any talk or tutorial about it, maybe this is not reliable for game need ?
I tried to generate motion vector from a flipbook animation. I’m slowly getting there but my math skill and Houdini’s knowledge hitting a wall now.
I know they could be generated with the gamedev toolkit but I want to use 2d source for all my flipbook need , like more motion graphics stuff ect.
As you can see I’m almost there (kinda?), but few things are off, It seem my vectors are flipped somehow and don’t errr spread enough ?
Here’s my hip file, hope you don’t mind some of my math/logic foolishness.
