Abstract
A method which derives for each triangle to be rendered the values of the texture map coordinates in world space and the screen space two dimensional coordinates across the polygon, utilizes the values to provide two bounding boxes, compares the values of sides of the bounding boxes, and uses these comparisons to select a texture map of a scale which will provide an accurate color representation of a texture value for the pixels of the polygon.
