Abstract:
A texture mapping method for determining a texel value to be applied to a pixel on a computer screen, said applied texel value derived from one or more texels from a texture map in which texels are referenced by a multi-bit digital u coordinate and a multi-bit digital v coordinate, said method comprising the steps of:determining a u,v coordinate in the texture map, said u,v coordinate including an integer portion and a fractional portion and said texture map being divided into a plurality of regions, each of the plurality of regions defined by predetermined distance boundaries from nearest adjacent texels; determining in which region said u,v coordinate is located; and implementing one of a plurality of different preselected filtering techniques to derive said applied texel value, the selected filtering technique being selected in response to which region said u,v coordinate is located.
