To demonstrate our approach we lit several scenes, mainly using a direct illumination renderer designed for computer cinematography, but also including examples of global illumination and non-photorealistic rendering styles.
One standard benchmark for the rendering of computer models into graphical images is the Utah Teapot, created at the University of Utah in 1975.
From 1979 to1984, he was an associate professor of electrical engineering at Stanford, where he developed the Geometry Engine, an early hardware accelerator for rendering computer images based on geometric models.
Graphics processing units (GPUs), the hardware responsible for rendering computer games, are powerful parallel processors.
The Graphics Processing Unit (GPU), originally designed for graphics rendering on computer and gaming systems, has recently emerged as a powerful, cost-effective supplement to the Central Processing Unit (CPU) for dramatically accelerating scientific computations.

Taking a firm first used as a video rendering computer for medical use, Pixar was repurposed into a firm that creates groundbreaking computer-animated movies.
Since reproducing the visual realism of the real world is a major goal for computer graphics, textures are commonly employed when rendering synthetic images.
Many surveys have been done for computer representation of trees for realistic and efficient rendering.
Storing a complete BRDF sufficiently densely for computer graphics needs is likely to require millions of points, and accessing this data during rendering would significantly slow down a renderer.
