Implemented soft body Physics using a series of goal springs and surface springs to achieve nice jiggling effects. Done using Microsoft XNA 2.0.

Initially only goal springs are used to bind the deforming mesh to a morphing goal mesh. However, only local jiggles can be obtained. Surface springs are then used to connect the vertices together to give surface tension. This resulted in nice whole-surface jiggles. The comparison between these two version can be seen in the video below.

I am a Senior Technical Director with strong interests in both tech and art. My life evolves round VFX, photography, software engineering, tools programming and generally anything that looks / sounds cool.
I have done a variety of CG programming, including fluid sims, muscles, soft/rigid bodies, raytracing etc. These knowledge complement the visual works that I do as a TD in VFX.
I was interviewed by The Straits Times in May 2014 for my VFX work in X-Men: Days of Future Past.
