You can use InstanceMesh for performance optimization

Thanks for your feedback

I am in fact using an InstancedMesh for the 108 rollers . The sprockets go back to the work I showcased below, including CodePens. I don’t see, how sprockets could benefit from the usage of InstancedMeshes, too? But I’ll be happy to learn more …

Cloned: Kinematically correct roller chain sprocket generator

I was able to clone the original thread from the “History” of the one I accidentally deleted while accessing it from my mobile phone (fat finger syndrome … ): I got inspired by @jrlazz 's bicycle chain animation and thought I’d give it a try, too. In its current stage, it only generates kinematically correct sprockets - no chain and no movement. The sprocket contour comprises exclusively circular arcs and is computed on-the-fly, no pre-computed shapes are involved. Instead of many wor…

As far as performance is concerned: I’m getting full 120 fps both in Safari and Firefox, albeit on a beefy MacBook Pro M4 Max - so performance was not my prime concern.
