Abstract
A method and system are provided for drawing one or more surfaces. The system includes a drawing processor, a frame buffer with z buffer and a display device, such as a display monitor. The drawing processor can perform all of the following steps. A first pixel in a first row is selected. The first pixel is near a first point at which a projection onto a plane of view of a first edge of a first surface intersects the first row of pixels in the plane of view. A first distance from the first point to a second point on the first surface is determined. The first point is a projection onto the plane of view of the second point. The first distance is then corrected by a first value representing a difference in distance between the first distance and a distance from the first pixel to a third point on the first surface. The first pixel overlies, e.g., and is centered at, a point that is a projection onto the plane of view of the third point. The corrected first distance is assigned to the first pixel as representing a distance from the first pixel to the first surface.
