摘　　要：真实感图形学中大面积镜面物体反射效果一直难以模拟,在Irrlicht引擎的基础上采用渲染到纹理技术实时模拟了镜面反射效果,并对帧率的提高做了适当优化.实验结果表明,在不考虑多镜面物体之间互反射的情况下该技术可以准确地模拟镜面反射效果.Global view-dependent reflection of environment around is hard to simulate,especially for larger objects.In this paper,a different method for specular reflection without thinking interreflection between mirrors was put forward.Used rendering to texture to generate environment maps in real time,the results would be taken as textures.The process to raise FPS by choosing proper approximation were optimized,the results showed that it could simulate specular reflection accurately and efficient.
