摘要: In this paper, we proposed a low complexity subdivision algorithm to approximate Phong shading. It is a combination of a subdivision scheme using forward difference and a recovery scheme to prevent rasterization anomaly. Dual space subdivision, triangle filtering and variable sharing schemes are also proposed to reduce the computation. Compared with the conventional recursive subdivision shading algorithm, the proposed algorithm reduces 46.6% memory access, 80% projective transformations and perspective division, 93.75% clipping/culling tests and 60% 3x3 matrix multiplications for setup operation.
