A real-time globa relighting algorithm is proposed in this paper．The scene illumination is divided into three parts：direct，indirect and ambient components．After calculating the reflectance of objcots from reconstructed genmetry and pre-sampled images，indirect and ambient components of each sampled image are fitted with low-order basis functions To relight the soofle under new illumination conditions or viewpoints，the recovered reflectance is applied to the illumination model to get direct lighting．while indkect and ambient ones are obtained from the basis functions．In addition surface derails are recovered by the variations of the micro-property and orientations on the sulfaee computed from sampled images．The results show that this algorithm call reconstruct global illumination with clear shadow and surface detail vividly in real-time．
