Abstract :
With continuous improvement of VLSI technologies and request of higher realism, real-time Phong shading will be the next technology-push in 3D graphics. Taylor series approximation is appropriate for hardware implementation of Phong shading. We determined the hardware size of the Taylor series approximation in terms of hardware minimization through visual comparison and implemented Taylor series approximation in a 3-stage pipelined architecture
