摘要
This patent discloses a system and method to compile a set of display points that define a two dimensional representation of a straight line graphic object using three dimensional rasterization algorithms. In one embodiment, a three dimensional (3D) graphics accelerator may receive data. The data may define three vertices (x0, y0, K0), (x1, y1, K1), and (x2, y2, K2) of a triangle primitive. Attributes K2 = (K0 + K1)/2 and coordinates (x0, y0), (x1, y1), and (x2, y2) form an isosceles triangle primitive. Coordinates (x0, y0) and (x1, y1) define a base of the isosceles triangle primitive. The isosceles triangle primitive may be rendered using the three dimensional rasterization algorithms to obtain the set of display points that define a two dimensional representation of the base of the isosceles triangle primitive.
