Home > Ray casting

In computer graphics, Ray-casting is a pseudo- 3D rendering technique, a special case of ray tracing.

The technique consists of sending out one ray for each column of pixels, checking if it intersects a wall, and drawing textures on the screen accordingly, creating a depth buffer against which to clip the scaled sprites that represent enemies, powerups, and props.

Rayleigh scatteringRayleigh scattering (named after Lord Rayleigh) is the scattering of light by particles smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases.
