摘要

我们提出了IRTCD，一种利用空间和时间相干性的新颖迭代光线跟踪碰撞检测算法。我们的方法使用任何现有的标准光线跟踪算法，并且我们提出了一种迭代算法，该算法通过一些近似以较低的成本更新以前的时间步长结果。应用于刚体的迭代算法，与GPU上的非迭代算法相比，我们的迭代算法的碰撞检测速度提高了33倍。

New iterative ray-traced collision detection algorithm for GPU architectures

We present IRTCD, a novel Iterative Ray-Traced Collision Detection algorithm that exploits spatial and temporal coherency. Our approach uses any existing standard ray-tracing algorithm and we propose an iterative algorithm that updates the previous time step results at a lower cost with some approximations. Applied for rigid bodies, our iterative algorithm accelerate the collision detection by a speedup up to 33 times compared to non-iterative algorithms on GPU.
