abstract = "Realistic rain scenes animation is a complex task due to both the
rendering and fluid dynamics simulation issues. The associated
phenomena, like rain strokes rendering, splashing of raindrops and
the simulation of the generated surface flow are known
difficulties in this area. This paper describes a computational
framework to incorporate these elements in a scene containing a
digital terrain model (DTM). In the rain model, the raindrops are
modeled by a particle system implemented in GPU. Each particle
represents a drop and the Precomputed Radiance Transfer (PRT),
expressed in a spherical harmonics bases, is used to incorporate
environment lightning to the rendering engine. The Smoothed
Particle Hydrodynamics (SPH) method is employed for simulating the
superficial flow over the terrain and lake formations. The
rendering of the fluid free surface is performed by applying an
environment mapping technique plus Fresnel effects to a regular
geometric representation known as ``carpet''. The experimental
results show the potential of the proposed pipeline for computer
graphics and highlight the fact that it is a promising framework
for real time applications.",
