What slug-font-rendering does

This skill supplies reference HLSL implementations of the Slug algorithm. It calculates glyph coverage directly in fragment shaders using quadratic Bézier curves and lines, avoiding blurry textures when zooming.

The implementation includes slug.hlsl, curve.hlsl, and the band-based optimization in band.hlsl. It functions across rendering APIs like D3D11, D3D12, Vulkan, and Metal via translation layers.

Shaders cannot render text on their own without CPU preprocessing. You must convert TrueType or OpenType contours into curve records on the host and bind them to a GPU structured buffer.

What it helps with

  • render vector glyphs on GPU without precomputed font atlases
  • evaluate quadratic Bézier coverage directly inside fragment shaders
  • reduce per-pixel curve intersection tests using band culling
  • integrate Slug text drawing routines into D3D12 or Vulkan pipelines

Example prompts for the agent

  • Explain how to bind the curve structured buffer to slug.hlsl in DirectX 12
  • Write a CPU contour preprocessor that outputs quadratic Bézier segments for Slug
  • Show how band metadata reduces per-fragment curve evaluations in band.hlsl

Questions about slug-font-rendering

How do I install slug-font-rendering in Claude Code?

Run npx skills add reason-machines/trending-skills --skill slug-font-rendering -a claude-code in your terminal.

What is slug-font-rendering?

It provides HLSL shader references for the Slug vector font rendering algorithm, drawing glyphs on the GPU mathematically.

What prerequisites does Slug need on the host?

You must decompose font outlines into lines and quadratic Bézier segments on the CPU, then upload that data to a GPU buffer before invoking the shaders.
