**Visual Simulation of Waterfalls and Other Water Phenomena**

A set of relatively simple rules for use in modeling falling water, using a three-dimensional particle system. The rules have been applied to waterfalls, fountains, and rain.

**Volumetric Modeling with Implicit Functions: A Cloud is Born**
A new, flexible, natural, intuitive, volumetric modeling and animation technique that combines implicit functions with turbulence-based procedural techniques. A cloud is modeled to demonstrate its advantages.

**A Fast Algorithm for Illumination From Curved Reflectors**
Indirect illumination of a surface from a curved mirror is computed by considering the reflector as another light source. The illumination values are computed using only fast scan-line techniques.

**A General Model for Simulation of Room Acoustics Based On Hierarchical Radiosity**
A new method to compute the impulse response of a given virtual room based on hierarchical radiosity. Unlike previous work, this approach treats complex geometries and is listening-position-independent.
