WebRay 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 can encode volumetric data for volume ray casting, distance fields for accelerated intersection finding of surfaces, among other information. WebAbout External Resources.

WebMay 20, 2024 · 1. This is definitely possible. The idea is to use the same camera for ray tracing and for rasterization. You can get the camera's position from the camera matrix in the fragment shader and you can get the camera's direction by subtracting the fragments position from the camera's position and normalizing it. This way the rays are only cast …
