WebTechniques applicable to a ray tracing hardware accelerator for traversing a hierarchical acceleration structure with reduced round-trip communications with a processor are disclosed. The reduction of round-trip communications with a processor during traversal is achieved by having a visibility mask that defines visibility states for regions within a …

WebJan 10, 2024 · It returns the length of the ray from the origin to the sphere surface, or a -1.0 in the case of a miss. Nice and straight forward. So all we need is those three vectors and we’ve got a nice sphere. The ray origin is perhaps the easiest point to get. For a Unity shader, that’s going to be the camera position. WebSimple Ray Tracing. A simple ray-tracing algorithm can be used to find visible surfaces, as opposed to a more complicated algorithm that can be used to generate those o-so-pretty images. Ray tracing is an image based algorithm. For every pixel in the image, a ray is cast from the center of projection through that pixel and into the scene.
