Abstract: A system, method, and computer program product are provided for conservative rasterization of primitives using an error term. In use, an edge equation is determined for each edge of a primitive, the edge equation having coefficients defining the edge of the primitive. Each edge of the primitive is shifted to enlarge the primitive by modifying coefficients of the edge equation defining the edge by an error term that is a predetermined amount. Pixels that intersect the primitive are then determined using the enlarged primitive.

Abstract translation: 提供了一种系统，方法和计算机程序产品，用于使用错误项保护原语的光栅化。 在使用中，为原语的每个边缘确定边缘方程，边缘方程具有限定原语边缘的系数。 将原语的每个边缘移位以通过修改定义边缘的边缘方程的系数通过预定量的误差项来放大原语。 然后使用放大的图元确定与图元相交的像素。
