PRIMITIVE BINNING METHOD FOR TILE-BASED RENDERING |
摘要 |
A primitive binning method includes detecting border tiles of a primitive defined by at least three vertexes. The detecting includes: defining a left edge and a right edge of the primitive compared to a direction of exploring tiles; calculating a slope sign for the left edge using an edge equation for the left edge; calculating a slope sign for the right edge using an edge equation for the right edge; and checking if a tile is crossed by one of the edges by evaluating an edge equation of a single corner of a tile. The corner is selected according to the one of the edges being a left or a right edge and according to the slope sign of the one of the edges.
