If an application implements a ray-marching graphical effect such as Screen Space Reflections (SSR), the algorithm should implement an optimal sampling technique which takes as few samples as possible to achieve the desired quality. One possible approach to reducing the number of samples is to perform the ray marching in …

Ray marching is quite similar to ray tracing, however it has some interesting quirks that make it an interesting option for real-time graphics demos and games. First, I should note that ray marching is not a replacement for rasterization nor ray tracing, it's just a cool alternative.
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 … Ver mais 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 function … Ver mais The 1989 paper Hypertexture by Ken Perlin contains an early example of a ray marching method. Ver mais 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 … Ver mais When rendering screen space effects, such as screen space reflection (SSR) and screen space shadows, rays are traced using Ver mais
