Graphics & animation experiments.
Field / Form
A realtime particle experiment built for this site. Position and velocity are computed on the GPU, with responses to navigation, pointer movement and scrolling. The Lab lets you change forms and rendering paths and inspect the source.

An animation compression experiment that represents hand and foot motion as IK targets. I started with FK-to-IK conversion and am exploring reconstruction from fewer keyframes.
Approach and validation plan
- FK → world pose → IK targets
Extract hand and foot positions and pole vectors from the bone hierarchy’s world transforms. The first step is to reconstruct the pose with Two-Bone IK and compare it with the original.
- Sparse keys + interpolation
Select keys from target trajectories and use Lerp/Slerp interpolation as a baseline. Correction deltas would preserve rotations that IK alone cannot retain. The plan is to evaluate position and rotation error, ground contact and file size together.
- ML interpolation
A later stage would test whether learned interpolation improves on the baseline, accounting for the cost of downloading the model and running inference.
