A new technique for rendering convective clouds is suggested. The technique uses two lattice-Boltzmann (LB) models, one for generating the spatial and temporal distribution of water density and the other for photon transport , that is, lighting the water density with correct anisotropic scattering. The common LB structure is easily mapped to parallel(More)
Numerical solution of any large, three-dimensional fluid flow problem is a computationally intensive task that typically requires supercomputer solution to achieve reasonable execution time. This paper describes an alternative approach, a technique for mapping three-dimensional fluid flow models to low-cost, desktop hardware. The approach is shown to(More)
This paper presents a simple and efficient algorithm for achieving real-time performance on current consumer graphics hardware when rendering complex, dynamic scenes with direct and secondorder diffuse (indirect) illumination. An image space, low-discrepancy sampling technique for positioning point lights is presented. These point lights simulate(More)
Real-time cinematic relighting of large, forest ecosystems remains a challenging problem, in that important global illumination effects , such as leaf transparency and inter-object light scattering, are difficult to capture, given tight timing constraints and scenes that typically contain hundreds of millions of primitives. A solution that is based on a(More)
