Abstract:
A computer-readable recording medium storing a program for 3-D computer image processing which displays a shadow of a solid model drawn in a virtual 3-D space of a monitor screen as a shadow object, wherein said medium stores a program comprising:a source code segment imparting a shadow object to each of the solid models to be drawn; a source code segment determining whether multiple shadow objects are superimposed from a positional relationship between shadow objects imparted to the solid models to be drawn, the determination comprising setting a flag showing the presence of shadow objects in correlation with monitor screen positions of the shadow objects, and determining superimposition of the shadow objects with reference to the flag, one flag being associated with each area on the monitor screen; and a source code segment conducting drawing processing, for an area where there are superimposed shadow objects, which displays only one shadow object from among the superimposed shadow objects.
