Filed: 1993-10-04
Abstract: PURPOSE:To unnecessitate the conversion of a standard vector of a polygon by processing the projection vector which defines the edges of the polygon in a screen space to decide whether the projected polygon is set forward or backward. CONSTITUTION:The image data are written into a memory device 16 by the input instruction given from an input device 17 after a position is defined in a virtual three-dimensional space. Then the image data are converted among plural three-dimensional spaces. The data stored in the device 16 consist of a table of apexes which is defined by making reference to the X, Y and Z coordinates, an the subject selecting/eliminating process includes the check of the X, Y and Z coordinates so as to identify an apex range in each dimension of a subject. In regard of a projection vector which defines the edges of a polygon in a two-dimensional screen space, a backword polygon is decided and eliminated if the gradient of the vector which connects the highest apex to its precedent one is smaller than the gradient which connects the highest apex to its next one.
