Author(s): Fengquan Zhang, Jiaojiao Guo, Jianfei Wan

One of the important research targets in the Augmented Reality system is the consistent illumination of virtual objects with respect to the real-world environment. It plays an important role in the mixing of virtual and real scene. After researching on the relevant issues, a real-time illumination system was developed to resolve the consistent illumination problems of the indoor mixed reality application, and the good effects have been obtained. To produce shade and shadow effect on the virtual object, the renderer utilizes pre-computed radiance transfer to calculate the wavelet coefficients, and uses these coefficients in vertex shader on GPU during rendering to achieve interactive frame rates
