A lazy object-space shading architecture with decoupled sampling
We modify the Reyes object-space shading approach to address two inefficiencies that result from performing shading calculations at micropolygon grid vertices prior to rasterizati...

Accelerating shadow rays using volumetric occluders and modified kd-tree traversal
Monte Carlo ray tracing remains a simple and elegant method for generating robust shadows. This approach, however, is often hampered by the time needed to evaluate the numerous sh...

Using semi-lagrangian formulations with automatic code generation for environmental modeling
An import issue for numerical weather prediction modes (NWP) is the time it takes to produce a valid forecast. One factor, which greatly influences this simulation time is the si...
