The hidden lines and surfaces of two interfering objects to be displayed in two-dimensions, are calculated by considering the polygonal plane surfaces defining each object, dividing them into triangles, projecting one triangle of one object onto the plane of a triangle of the other object, calculating a 4 x 4 determinant of the vertex coordinates of one triangle and one vertex coordinate of the projected triangle, determining intersection points to define hidden lines and surfaces and repeating as necessary. |
