What does GLSL Shader Editor do?
Write GLSL fragment shaders with live WebGL preview — u_time, u_resolution, and u_mouse uniforms are pre-wired so animation and interactive effects work immediately without boilerplate setup.

Edit vertex and fragment GLSL shaders and see the result on a 3D mesh in real time. WebGL / GLSL ES 1.0. Uniforms u_time, u_resolution, and u_mouse are available.
Tip: Tab = 2 spaces, Shift+Tab = outdent. Enter = new line with same indent. Wireframe = compile error; check console (F12).
Drag to rotate. Mouse position is passed as u_mouse (0–1).
Vertex shaders run per vertex and set gl_Position and pass data via varying. Fragment shaders run per pixel and set gl_FragColor. This tool uses sphere, plane, or cube geometry; you can use uv and position in the vertex shader. Use u_time, u_resolution, and u_mouse for effects.
