Description

This is my 2012 pure WebGL 1.0 Experiment, without 3th party WebGL tools/library.

It uses only gl-matrix js library for 3D transformations, and other self-made tools in the jsLib directory

Warnings

For standalone use, on local computer, need of an http server to load external glsl shader file.

Commons workarounds

For safety the browsers can't load external files from local machine, but if you want to test this experiment, without a http server, you can use a workaround:

Chrome

Launch browser with --allow-file-access-from-files command line option.

Firefox (from v.68 and above: before works fine w/o any settings)

In about:config url (config page), set privacy.file_unique_origin = false
