Abstract: We present a technique for simulating the physical appearance of paint strokes under lighting. This technique is easy-to-implement and very fast, yet produces realistic results. The system processes a painting composed of a list of brush strokes. A height map is assigned to each stroke, and a height field for the painting is produced by rendering the brush strokes textured with the height maps. The final painting is rendered by bump-mapping the painting's colors with the height map. The entire process takes only a few seconds on current hardware.
