Sphere tracing In sphere tracing, or sphere-assisted ray marching an intersection point is approximated between the ray and a surface defined by a signed distance function (SDF). The SDF is evaluated for each iteration in order to be able take as large steps as possible without missing any part of the surface. A … See more Ray marching is a class of rendering methods for 3D computer graphics where rays are traversed iteratively, effectively dividing each ray into smaller ray segments, sampling some function at each step. This … See more The 1989 paper Hypertexture by Ken Perlin contains an early example of a ray marching method. See more In volumetric ray marching, each ray is traced so that color and/or density can be sampled along the ray and then be combined into a … See more When rendering screen space effects, such as screen space reflection (SSR) and screen space shadows, rays are traced using G-buffers, where depth and surface normal data is stored per each 2D pixel.
