A related talk of using Mesh shaders for Alan Wake 2 https://youtu.be/EtX7WnFhxtQ?si=MFQBcstqyudDlzj_

And I find Apple’s intro to mesh shading to be a fairly good primer for someone unfamiliar with Mesh shading

Can you recommend any good write ups or articles for this topic?

Here is one article on this topic: https://gpuopen.com/learn/mesh_shaders/mesh_shaders-index/

thanks!

AMD's "From vertex shader to mesh shader" [1] helps navigate between the older pipeline to the newer pipeline. Links in the sidebar get into other things like procedural geometry.

"Mesh Shaders and Meshlet Culling in Metal 3" [2] was also a good tutorial to learn about the mesh shading computation model.

I did most of my work in Metal. Apple WWDC's "Transform your geometry with Metal mesh shaders" [3] helped introduce it there. I liked playing with it in Swift -- this was a port of Apple's demos to Swift [4]. The Metal Shading Language manual also helps get your head around it. [5]

I always hear that geometry shaders are slow. Why are they slow?
