Rendering

An alternate term for rasterization. See Rasterization.

In digital imaging and three-dimensional modeling, the application of shading and color variations to an image to provide the illusion of depth, or a third dimension. Computerized rendering utilizes mathematical formulas to determine the location of a light source in relation to the object being rendered, and calculates the manner in which the light source would affect shadows, highlights, and color variations.

[Flat Rendering: A simple shading scheme that sssigns all pixels in a polygon the same color.

Gouraud Rendering: A shading algorithm devised by Henri Gouraud in which each pixel on a surface is calculated as an average from the color and illumination at the corners of the wireframe polygon in which it is located.

Phone Rendering: A shading algorithm due to Phong Bui Tuong that computes each pixel of a surface based on the color and illumination at that pixel. This is more accurate than Gouraud shading, but also more compute-intensive. However, it is less demanding than ray tracing.Providing the coloring, shading and modeling to allow an image to simulate reality.]
