Abstract: Water surface and other effects are efficiently simulated to provide real time or near real time imaging on low-capacity computer graphics computation platforms. Water and other surfaces modeled using multiple independent layers (1002) can be dynamically adjusted in response to real time events (1006). The number of layers used in a given area can be adjusted to reduce computational loading as needed. Different algorithms can be employed on different layers to give different effects. The multiple layer modeling is preferably converted to polygons using an adaptive polygon mesh generator based on camera location and direction in the 3D world (1008) to provide automatic level of detailing and generating a minimal number of polygons (1010). The visual effects of water droplets and other coatings on see-through surfaces can be modeled and provided using indirect texturing.
