一种光线与三角形求交算法的硬件架构设计

为了实现实时性的光线追踪平台，提出了一种光线与三角形求交算法的硬件架构设计。首先介绍了一种光线与三角形求交的简洁算法。该算法与其它算法相比使用存储空间最少，却具有相似的性能，便于硬件实现。根据此算法，提出了相应的硬件架构，在架构设计过程中，通过折叠、资源共享、以及多线程等硬件架构设计方法来提高硬件使用率，使有限的硬件资源达到最高的性能。实验结果表明，与现有方案相比，本文硬件架构平台在速度和芯片面积两个方面都存在着较大的提高。为实时光线追踪的实现提供了依据。

Hardware Architecture Design of Ray-Triangle Intersection

For interactive ray tracing, this paper proposes a hardware architecture design of ray-triangle intersection. First of all, a minimum storage ray triangle intersection was introduced. The algorithm uses minimum storage space compared to other algorithms, but with similar performance and convenient for hardware implementation. According to this algorithm, this paper presents the hardware architecture, several hardware design techniques such as multi-threading, folding and resource sharing are used to increase the hardware utilization. Experimental results show that this hardware architecture platform has a wider improvement in terms of speed and chip area, which was compared with other platforms, which provides an effective solution for interactive ray tracing.
