A practical and controllable hair and fur model for production path tracing
Matt Jen‐Yuan Chiang, Benedikt Bitterli, Chuck Tappan, Brent Burley · 2015
We present a novel BFSDF that is energy-conserving, efficient, and easy to control, reproducing a wide range of hair and fur with just a few intuitive parameters. This model is implemented in our production path-tracer and has achieved unprecedented richness in our characters.
