WebSep 30, 2024 · Obtaining the correct occlusion relationship between real objects and virtual objects is vital for improving augmented reality technology. In this paper, we propose a novel occlusion handling method using moving volume and ray casting techniques. Our method is divided into two steps. In the first step, we obtain the volume of the corresponding … WebJan 24, 2024 · This PR includes CPU/GPU compatible ray casting that renders vertex map and color map (demo only, with artifacts). In a typical indoor scene, it takes per frame 20~30 ms on GPU 150~300 ms on CPU with the highest resolution (0.0058 meter), including both TSDF integration and ray casting.

WebWe seek to evaluate the accuracy of ray-distance calcula-tions versus Euclidean distance calculations given different numbers of viewpoints from a realistic vision-based sensor. We first remove the truncation requirement of the TSDF, and then evaluate how the ray distances compare to true Euclidean distances for planning purposes, and propose a WebApr 7, 2024 · The principal RTX engine provides hardware acceleration for determining the first thing a ray hits in a BVH. According to what I see as a common definition of "ray-casting", that seems to be the definition. I'm not sure what Min/Max ray casting is, but based on your definition here it would probably involve multiple ray traversals in the RTX ...
