资 源 简 介
This project is a multithreaded software rasterizer built on SDL. It was written as part of a year-long research requirement at Taylor University. Supported features include custom vertex and pixel shaders, a quad-filled pixel pipeline heavily optimized for SSE, polygon clipping, half-space rasterization, depth occlusion with z-buffering, as well as perspective correct attribute interpolation. An custom written, SSE optimized math library is included as well.
Performance scales very well to then number of physical threads on the CPU. A dual core, Hyperthreaded Intel I5 saw a 2.5x speedup from 1 thread to 4 threads. A core I7 saw a 4x+ speedup from 1 to 8 threads. SSE 4.1 is utilized, so a recent CPU is required.
