Method of and system for generating images of object transforms.

摘要

A method of generating a two-dimensional (2-D) image of a transform of a three-dimensional (3-D) solid object (in 72) comprises sub-dividing (in 60) a 3-D box (in 62, 64) defining viewing space (in 54) into sub-boxes, generating test-cells in object space by performing an inverse transform (from 56) on the sub-boxes and determining (in 66) which of the test-cells intersect the object. Thus, the need to transform the object itself is avoided. A particular application of the method is the generation of 2-D perspective images of a 3-D solid object. A graphics processing system comprising means for performing the method is defined.
