3D Object Animation Enhancements

Thanks for the contributions so far, we are now between Phase 2 and 3 in development. The latest version is available here:

Contributor perks: early release versions of the enhanced addon, before the public release after full development.

Create GPU based animation for skinning and rotation, translate, scaling animation. This take almost all of the CPU related performance and puts it where it - belongs in the GPU vertex shader. This greatly improves the CPU animation performance with a small impact on GPU performance.

Once fully funded, the updated addon will be added to main branch of the public repo and available on the free itch page.

I have found on old 2017 iMac, I can get at least 10M triangle/frame, animating at 20fps with a 60Hz refresh rate and has more headroom beyond this. This is with a nice complex model. Without GPU Skinning the same scene refreshes at 2-3fps. I have also seen a nice level of improvement on iOS and Android mobile.

For static geometry, I have already done development to improve static geometry rendering by storing the geometry data on the GPU.

The bulk of this work is all done with direct webgl calls, which does not rely on C3 SDK (V1 or V2) or C3 engine internals. There is one change which requires a change to the default C3 vertex shader, but in later phases, I look to replace that, with my own shader, so that is no longer required.

Phases based on funding:
Phase 1, +$500 - base funding
