An Optimized Soft 3D Mobile Graphics Library Based on JIT Backend Compiler

摘要

Mobile device is one of the most widespread devices with rendering capabilities now. With the improved performance of the mobile device, displaying 3D scene becomes reality. This paper implements an optimized soft 3D mobile graphics library based on JIT backend compiler, which is suitable for the features of the mobile device. To deeply exploring the advantages of JIT technology, this paper improves the traditional rasterization model based on JIT technology and proposes a hybrid rasterization model which integrates the advantages of both the per-scanline and per-pixel rasterization models. As we know, the backend compiler is the critical factor in running 3D application programme. In this paper, we implement a backend compiler for certain CPUs and propose some optimization techniques accordingly. The experimental results indicate that our 3D graphics library has achieved fine performance.
