| 摘 要： | 针对全局光照尤其是多光源的全局光照的复杂性使其一直局限于离线应用的问题.对能量大的能代表多个光源的主光源,采用立即辐射度的方法,跟踪其光线产生虚拟点光源(VPLs:Virtual Point Lights),这些VPLs再照亮场景实现实时的一次反射的间接光照.对场景中其他非主光源采用预计算光照图的方式计算其直接光照,动...

| Abstract: | The complexity of many-light global illumination has been limiting its use only to off-line applications.We firstly approximates many light by a single brighter light,and the light paths are traced from this representative light,and VPLs(Virtual Point Lights) are generate at the vertices of these paths.Then,those VPLs are used to illuminating the scene,thus single-bounce indirect illumination can be rendered on currently available graphics hardware at real time rates.The direct illumination of other lights ... |
