ShaderGraph

ShaderGraph is a focused tool for shader preview and accurate shader-math graphing.

Use a real Flutter runtime fragment shader preview, adjust live uniform controls, and inspect six GLSL-style function channels beside the result. It is designed for experimenting with shader formulas, shaping functions, signal curves, SDF helpers, and preset visual scenes without leaving your device.

Features:
- Runtime fragment shader preview powered by Flutter FragmentProgram.
- Six-channel function graphing for shader debugging.
- Presets for aurora fields, warped rings, and signal grids.
- Uniform controls for scale, warp, glow, contrast, palette, and grid strength.
- Expression support for sin, cos, fract, step, smoothstep, mix, clamp, pow, and more.
- Copyable export payloads for formulas, parameters, and graph ranges.

Privacy-first by design: ShaderGraph runs locally, stores preferences on the device, does not require an account, and does not collect, transmit, or share personal data.
