Raymarching optimization

WebRayTK is a library of TouchDesigner components that construct raymarching shaders (and other types of shaders) with networks of COMPs using the TouchDesigner network editor. RayTK consists of a set of operator (ROP) components, and tools for working with them. The goal of RayTK is to allow artists without a strong knowledge of GLSL to render ... The voxel world is divided into groups of 32 x 32 x 32 blocks, each of which are managed by a separate Chunkclass instance. This structure is especially useful for: 1. Rendering optimisations, as chunks outside the current viewport can be skipped 2. Fast mesh regenerationwhen blocks in a chunk are changed 3. … See more Chunks are stored in a three-dimensional array within the Map class, however Blocks are stored in a one-dimensional array in the Chunkfor … See more The problem with the original ray marching algorithm in Sector's Edge was that it worked with map-relative positions.

WebSep 16, 2024 · GM Shaders Mini: Raymarching. Xor. Sep 16, 2024. Howdy folks, Today we're covering "raymarching" or specifically "sphere-assisted ray marching" which is a powerful raycasting algorithm. It's frequently used by shader enthusiasts because it's relatively easy to work with and can add extra effects like soft shadows, and glow as a byproduct.

We only trace one cone/ray though, but at higher roughess cone tracing can skip many pixels by sampling the higher mip levels.

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