Abstract
A method for drawing a 3D triangle includes decomposing polygons into triangles. The triangles are then truncated into trapezoids, so that they may be drawn in the same direction, such as always top to bottom and left to right. The Z error values are determined for each trapezoid. This allows initial Z values to be correct. The ERROR values may be determined for other triangle attributes such as color, translucence, and texture.
