WebApr 5, 2024 · Raymarching is a mathematical way of rendering. It is done with distance fields (distance from a point to a primitive), constant-steps (typically used with volume rendering), and root-finders (a math approach). Normally, creating a scene like this requires tools for geometry (Maya, Blender, 3DsMax), tools for textures (Photoshop, Gimp, MSPaint).

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. WebAdvantages of raymarching include extremely simple rendering of procedural isosurfaces and easy CSG, along with ease of implementation in modern shading languages.
