1. Savva. (procedural animates trees)
Forest generation system consists of custom Maya nodes for wind simulation and geometry shader for creating the tree itself. User can convert an ordinary model of a tree into the system-ready one with a script that calculates each leaf orientation and fixing point on a branch. Branches sway in the wind and leaves follow them accordingly.
Geometry shader can generate a huge number of trees at render time.
module for simulating a special case scenario dynamics of glass debris. Specific shards can be set to stick to character's surface precisely. Shock wave from the impact affects shards around the collision area with a falloff. User can control all kinematic parameters.
Custom emitter creates particles in the regions where glass shards shift.
3. Savva. (Eye system)
Eye generation system consists of two shaders and a setup script.
Geometry shader generates parametrized surface of an eyeball with round or slit pupil.
Texture shader is a procedural pattern of an iris and blood vessels.
Blood vessels pattern is seamless.
Script builds the whole system automatically.
User can control all of geometry and texture parameters.
