Raymarching是什么意思
WebMay 23, 2024 · After rasterizing these, each pixel passed to the fragment shader represents a single ray. 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. WebSep 28, 2024 · Enter ray marching: the unappreciated cousin of ray tracing. 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.

The technique is particularly interesting because it is entirely computed in a screen-space shader. In other words, no mesh data is provided to the renderer and the scene is drawn on a single quad that covers the camera’s field of vision.
