Apparatus and process for graphically representing three-dimensional objects in two-dimensions |
摘要 |
A process for the perspective representation of objects on the picture screen of a numerically controlled machine tool is described in which the object is resolved into a series of sections which are represented successively with a given perspective offset. In order to avoid the representation of covered edges of these sections, the contours of the individual section surfaces are checked prior to being represented in order to determine whether or not they overlap a previously represented contour. This checking occurs through a simple coordinate comparison, taking into account the actual perspective shift between sections.
