Marco D’Ambros shows how to create a bulge deformer using Matrix math rather than raycasting.

Over the last little while, Technical Director Marco D’Ambros offers up little focused tutorials diving into recreating rigging tasks using Maya’s Bifrost. A new set of videos shows how to build a bulge deformer using Maya Bifrost, only using Matrix nodes rather than relying on raycasting.

D’Ambros covers how to make the deformer and then dives into the theory of why and how it all works using a Matrix computation for optimizing the collision system.
