All you need to work out the size and location of a sphere is a point in 3D space (expressed as XYZ coordinates, e.g. (1, 0, 1)) and a radius e.g. 5. So instead of a mesh of folded triangles which could have thousands of associated numbers, we have four numbers which is a pretty impressive bit of spring …
WebSep 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.Here's a 3D burger shader I made using a …
