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 … WebConcept. Ray casting is the most basic of many computer graphics rendering algorithms that use the geometric algorithm of ray tracing.Ray tracing-based rendering algorithms operate in image order to render three-dimensional scenes to two-dimensional images. Geometric rays are traced from the eye of the observer to sample the light travelling …
