Title:
- Engineering Full-Fidelity Hair for Incredibles 2
Presenter(s)/Author(s):
Abstract:
For Incredibles 2, we achieved interactive full-fidelity procedurally-generated hair, yielding artist freedom and productivity surpassing our previous hair tools. We implemented highly parallel algorithms for hair growth and deformation and used fast, modern techniques for graph evaluation, subdivision surfaces, Poisson disk sampling, and scattered data interpolation. Working with full-fidelity hair presented a data scale challenge to our shot pipeline, but we overcame it by allowing a trade-off of control flexibility for speed, maintaining geometric complexity.
