- ray casting — (graphics) A simplified form of ray tracing. A ray is fired from each pixel in the view plane, and information is accumulated from all the voxels in the volume data it intersects. Each voxel is first given an associated colour and opacity. The ray is sampled at a fixed number of evenly spaced locations and the colour and opacity are trilinearly interpolated from the eight nearest voxels. These are then composed linearly back to front to give a single colour for the pixel. Ray casting was invented by John Carmack for the game Wolfenstein 3D. It is faster and lower quality than ray tracing, and is ideal for interactive applications. It parallelises well, although random access is needed to the voxels.
- ray tracing — (graphics) A technique used in computer graphics to create realistic images by calculating the paths taken by rays of light entering the observer's eye at different angles. The paths are traced backward from the viewpoint, through a point (a pixel) in the image plane until they hit some object in the scene or go off to infinity. Objects are modelled as collections of abutting surfaces which may be rectangles, triangles, or more complicated shapes such as 3D splines. The optical properties of different surfaces (colour, reflectance, transmitance, refraction, texture) also affect how it will contribute to the colour and brightness of the ray. The position, colour, and brightness of light sources, including ambient lighting, is also taken into account. Ray tracing is an ideal application for parallel processing since there are many pixels, each of whose values is independent and can thus be calculated in parallel. Compare: radiosity.
- reactionary — of, pertaining to, marked by, or favoring reaction, especially extreme conservatism or rightism in politics; opposing political or social change.
