WebSDF Raymarching Algorithm: "Coverage Search". The "coverage search" algorithm is a SDF raymarching algorithm I came up with in an effort to try to solve ray hit/miss in fewer iterations than sphere tracing. For this, you need the ray origin and ray direction as before, but also an estimated start and end travel distance (such as from the ray ...

Fortnite's usage of SDF tracing for distant sun shadows comes to mind, and diffuse GI may also be a good fit since that's inherently a low-pass filter.

But if you want to draw a grid 100 spheres, you have 1000 operations with raytracing, while with raymarching, you just have to add 4 operations to each distance estimation, which makes it 8 operations per step, which be likely be less than 1000.

We present a method to analytically ray trace the surface inside each voxel in an SDF grid. The surface inside a voxel is a third-order polynomial as was derived by Parker et al. [1998]. Our method uses substantially fewer operations than theirs. In addition, Parker et al. did not provide continuous normals between voxels, which

WebNov 9, 2024 · The best way to start to explore ray tracing is to start by observing nature. In nature, rays of light are emitted from a light source. That light bounces off a surface. That bounce can be specular where it changes direction — either through a reflection or refraction — or it can be diffuse where it scatters in all directions.
