Description

A planet generator made using my new ray marcher. It uses layers of 3D value noise to displace the surface of spheres. The ray marching process finds an intersection point for each pixel. Once the end of the ray has entered the planet's bounding sphere, it takes small steps, sampling the noise texture after each step, until the ray has hit the surface. Value noise tends to look unnatural and grid-like by itself, but these artifacts become somewhat hidden if you layer the noise multiple times at different sizes. The resulting noise isn't the best, but it's good enough that patterns in the noise are not immediately noticeable. @piano_miles for the filmic tonemapping curve Minor update 2024-08-30 - embedded TurboWarp settings in project #3D #Raymarcher #Renderer #Pen #Planet #Generator #Procedural #Generation #Ray #Madness

Instructions

IMPORTANT: Use Turbo Mode (shift+green flag) and TurboWarp: https://turbowarp.org/416842874?turbo&hqpen Smaller pen size is higher image resolution, and the noise offsets control the shape of the terrain. Drag the sliders, and click the screen to begin rendering. - @SpinningCube
