ABSTRACT:
The picture drawing method is in a graphics computer, a special effect device or a video game machine. Data required for picture drawing is generated by pre-processing by a pre-processor32based on a drawing command for drawing a picture model defined by the combination of unit figures, and pixel data is generated on the unit figure basis by texture mapping based on the generated data for drawing a picture on a frame buffer18. The texture data required by a drawing engine33is transferred in the pre-processing stage from a texture area on the frame buffer18to a texture cache33F, and the pre-processor32and the drawing engine33are operated in pipelining. This enables texture mapping or MIP mapping without halting picture drawing, while reducing the number of times texture memory accessing and the accessed time for raising the overall picture drawing speed.
