shader-sdf

What problem does it solve?

This Skill provides a ready-to-use library of 2D and 3D Signed Distance Functions (SDFs) in GLSL, enabling rapid creation of procedural shapes, text effects, and smooth morphing without hand-crafting geometry.

Core Features & Use Cases

• 2D & 3D Primitives: Circle, Box, Sphere, Ring, Polygon, Star, Heart and more, with clean, reusable GLSL functions.
• Boolean & Domain Operations: Union, Intersection, Subtraction, Smooth variants, repetition, twist, bend, onion, and round operations for complex shapes.
• Transformations & Rendering: Translation, rotation, scaling, symmetry, and 2D/3D rendering techniques (AA, glow, outline).
• Procedural Graphics & Raymarching: Build raymarched scenes and visual effects using a compact shader toolkit.

Quick Start

Load the shader-sdf skill into your shader project, start with a simple circle using sdCircle(p, r), and render it with a basic raymarch loop. Then combine shapes with opUnion and apply translations or rotations to create more complex visuals.
