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. Web1 ray per pixel can still generate high quality results with great denoiser. Resource balancing Our traversal system runs on the RDNA WGP and uses LDS extensively.
