%X A synthetic approach was proposed for rendering diffuse and glossy reflections in real-time by using environment map, which solved the real-time computation of diffuse and glossy reflections under globally incident fighting. By means of hierarchical original environment map the filtering algorithm of diffuse map was improved and accelerated. And the glossy map could be achieved using hardware under the circumstance of keeping the fidelity. In the end, the programmable graphics pipeline completes the illumination computation and rendering. The experimental results show that this approach can get satisfactory effect in VR applications.
