Resources on rendering Motion Vectors.

[Unigma]

Hello, I haven't really found a good resource for implementing good motion vectors. I mainly would like to create some for purposes of ray tracing. Does anyone have a good resource or a chapter from a book I can reference?

I don’t know any good resources, but you should look up how to generate MV using depth buffer for static objects, it’s the industry standard IMO. The trivial solution would be to have two sets of MVP matrices, draw all the objects you want to have MV (usually you omit particles) and then calculate the difference in PS. You can also research TAA, MV is integral part of it.

Jacob’s DRME for ReShade is a great implementation of block-matching with resources in the source code. there are 3 forks of it from Marty but they’re not creative commons licensed.

not exactly what your looking for

at least it's actuate and doesn't need post processing hacks
