    Real-time non photorealistic paint spreading using stencil volumes



    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 mimics the known artistic effect of a monochrome image with colored highlights to emphasize certain areas, found in painting, film and other media.
