84 results about "Parallel rendering" patented technology

Parallel rendering (or distributed rendering) is the application of parallel programming to the computational domain of computer graphics. Rendering graphics can require massive computational resources for complex scenes that arise in scientific visualization, medical visualization, CAD applications, and virtual reality. Recent research has also suggested that parallel rendering can be applied to mobile gaming to decrease power consumption and increase graphical fidelity. Rendering is an embarrassingly parallel workload in multiple domains (e.g., pixels, objects, frames) and thus has been the subject of much research.
