【摘要】 设计和实现了GPU上基于流的光线跟踪算法,采用一种基于线索二叉树的KD-Tree结构组织场景,避免了传统KD-Tree结构在遍历场景时在堆栈上的开销。算法在组织复杂场景上,优于利用传统KD-Tree和均匀剖分结构加速场景遍历的方法,在普通PC上实现了光线跟踪的快速渲染。更多还原

【Abstract】 Light tracking algorithm based on GPU with the stream architecture was designed and implemented.Meanwhile,to avoid the overhead in stack operation of the traditional KD-Tree when traversing,a KD-Tree structure based on threaded binary tree was used to organize scene.The method is superior to the use of traditional KD-Tree and uniform split structure to accelerate traversing in organizing complex scenes,and the rapid tracking rendering of light was achieved in ordinary PC.更多还原
