ABSTRACT:
A texture mapping apparatus graphically applies a texture pattern to a polygonal area of an object presented in a display plane. A memory is defined with a texture plane corresponding to the display plane for recording in the texture plane pattern data representative of the texture pattern. A zone operator truncates the polygonal area sequentially in a longitudinal direction to determine a set of parallel zones which extend along a lateral direction in the display plane, and to subsequently determine a set of corresponding zones in the texture plane. A segment operator interpolatively divides one parallel zone to determine a stripe of lateral segments, and to subsequently determine a group of corresponding segments within the corresponding zone of the texture plane. A point operator interpolatively divides each of the lateral segments to determine an array of display points arranged within the polygonal area in the display plane, and to subsequently determine an array of texture points in the texture plane, corresponding to the display points. An allocator reads out the pattern data recorded at the respective texture points from the memory, and allocates the read pattern data to the corresponding display points to thereby map the texture pattern to the polygonal area.
