glslviewer-shader-debug

What problem does it solve?

This Skill helps you debug fragment-shader math by producing deterministic, headless rendered previews so you can visually verify SDFs, gradients, masks, and contour shapes before relying on device output.

Core Features & Use Cases

• Shader translation guidance: Converts runtime-shader or SkSL-like snippets into standard GLSL by applying type, entry-point, and coordinate conventions.
• Headless rendering with glslViewer: Renders one or more .frag files into reproducible PNG images for visual inspection in environments without a GUI.
• Contour/mask visualization workflow: Encourages output patterns that make edge behavior and zero-crossings obvious using the provided template helper.

Quick Start

Use glslviewer-shader-debug to render your fragment shader into a headless PNG preview from a .frag file so you can compare the resulting contour or mask shape against expectations.
