Abstract

The realistic rendering of plants must take into account global illumination and lighting effects such as color bleeding and soft shadows. While the traditional rendering methods of radiosity and Monte Carlo ray tracing support these features, they often suffer from high memory requirements and long computational times. Photon mapping addresses these issues, providing a means to render scenes of arbitrary complexity with low time and memory costs. Plants often exhibit much complexity due to their multitude of plant organs such as leaves, pettles, and branches. This paper demonstrates how the rendering of plants and plant scenes benefit from photon mapping techniques in terms of illumination and efficiency. A shadow shader is introduced to simulate light interactions in plants by allowing passage of photons through surfaces. Key modeling considerations for plants and outdoor scenes are also discussed.
