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. 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 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 … 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 final pixel color. This is often used for example when rendering clouds or 3D medical scans. See more

The fragment shader marches that ray until it reaches the surface, returning the result (often just the depth value for texturing & shading in a separate full-screen pass). The exact steps depend a lot on the particular effect you're trying to achieve. irvine california directions
