Real-Time Non Photorealistic Paint Spreading using Stencil Volumes
Marc ten Bosch
SIGGRAPH 2005 Poster Session
I borrow the concept of a stencil volume from shadow volumes and apply it to the simulation of a fluid spreading on a surface, without resorting to a texture-based approach. I introduce stencil paint volumes that grow in real-time using a physically-based system. Points inside the paint volumes are rendered in color, and those outside in black-and-white.
This technique was originally developed for my game project, Orblitz
