Abstract:
Curves are used to represent assets such as fur, hair, and grass in CG and can be used for rigs that drive vegetation. Applying noise fields to create procedural wind on curves has been an attractive method for its speed, variability, and timeframe independence. However, this makes the wind appear artificial, lacking in both its dynamic nature that can be art-directed and its realistic interaction with objects. In this talk, techniques are presented to art-direct as well as enhance the realism of procedural curve wind in shots with the addition of collisions, shielding, gusts, and recovery. These techniques are in use in DreamWorks films providing Character Effects artists with significant artistic and realistic control over the wind on curves.
