Debugs GLSL fragment shaders by rendering visual outputs to PNG files for instant verification and troubleshooting.
The Shader Debugger skill streamlines GLSL development by allowing developers to render fragment shaders directly to static PNG images. This utility is essential for troubleshooting GPU rendering issues, verifying UV coordinate mapping, and inspecting shader math without the overhead of running a full game engine or simulation loop. By converting code logic into a visual artifact, it enables developers and AI assistants to analyze rendering artifacts, normalize coordinate systems, and isolate problematic shader code through rapid iteration.
