## What it is
A console-based OpenGL sandbox for rendering and live-editing 2D/3D GLSL shaders without a UI. It supports fragment and vertex shaders, textures, 3D models, custom uniforms, hot reload, and headless rendering, controllable via POSIX stdin/stdout or OSC.

## Use cases
- preview and iterate on GLSL fragment shaders from the terminal
- render shaders headlessly and export PNG image sequences
- test PBR material shaders on OBJ/GLTF models
- live-code shaders on a Raspberry Pi or embedded device
- script shader rendering pipelines via stdin/stdout or OSC
- debug shaders with histograms, buffer views, and bounding boxes

## When to choose
- you want a lightweight, UI-free shader viewer that runs in the console
- you need headless or scripted shader rendering and image export
- you develop shaders for Raspberry Pi, embedded, or WebGL targets
- you want to drive shader parameters programmatically via OSC or console commands

## When to avoid
- you need a full GUI shader IDE with node editors or visual debugging
- you require DirectX, Vulkan, or Metal shader support
- you want a browser-based shader playground like Shadertoy
