WebGL Ray Marching Distance Extimation intersection between MandelBulb and MengerSponge cube

• light (blinn-phong) and shadows with full settings
• ambient occlusion with settings
• subpixel subdivision
• level of details (epsilon)
• auto-progressive step of accuracy.
• settings MengerSponge parameters: iterations / rotation / increment / scale / offset
• settings MandelBulb parameters: iterations / power
• 10 color palette with offset setting

Shadow Deep and Density parameters start with a low value (for slow GPU): increment values to get a better render (Deep) or for smooth shadows (Density)

• LeftMouseButton -> Rotate object
• RightMouseButton -> Rotate light
• MouseWheel -> Zoom in/out
• shift + LeftMouseButton -> Pan

This is pure HTML/JS/WebGL2 experiment, without 3th party WebGL tools/library.

It uses only gl-matrix js library for mat/vec/quat, and other self-made tools in the jsLib directory

For standalone usage, on local computer, is necessary use an http server to load external glsl shader file (e.g. launch python -m http.server from repository directory and in your browser digit localhost:8000/nameFile.html)
