| 摘 要： | 森林的实时渲染及光照是视景系统中的一个难题.基于图像的渲染方法(IBR)由于渲染速度与模型复杂度无关,被广泛应用于场景重建.基于光流场(Light Field Rendering)的IBR技术,提出一种迭代投射算法来进行外形重建,实现了具有实时光影特征的森林效果.实验表明该算法结合了传统迭代、投射算法各自的优点,在质量和效率方面取得了平衡.

| Abstract: | Real-time rendering and lighting of forests is a difficult problem in visual system. Due to uncorrelated of scene complexity, the Image-based rendering techniques have been widely used for the scene reconstruction. An iterative-casting algorithm based on Light Field Rendering (IBR) is put forward to solve the reconstruction pro-
blem, and then realizes a real-time forests rendering with lighting effects. The experimental results show that this algorithm has combined the advantages of iterative and casting algorithms, gets a balance between efficiency and quality. |
