WebFeb 22, 2024 · Ray tracing still remains the main solution to create photorealistic content. We have also seen that rasterization and ray tracing allow to control all the parameters of the scene (lighting, object and camera) but require a lot of work time (geometrical and material modeling, lighting, texturing, animation, etc.) and rendering calculation time. WebRay tracing (physics) In physics, ray tracing is a method for calculating the path of waves or particles through a system with regions of varying propagation velocity, absorption characteristics, and reflecting surfaces. Under these circumstances, wavefronts may bend, change direction, or reflect off surfaces, complicating analysis.

"WebJul 20, 1999 · Ray Tracing Introduction. Ray Tracing is a global illumination based rendering method. It traces rays of light from the eye back through the image plane into the scene. Then the rays are tested against all objects in the scene to determine if they intersect any objects. If the ray misses all objects, then that pixel is shaded the background color.
