What Is This?

Overview

Shader Dev is a comprehensive GLSL shader development skill that provides 36 distinct techniques for creating real-time visual effects. Built for ShaderToy-compatible environments, it covers the full spectrum of modern shader programming, from foundational ray marching and signed distance function modeling to advanced fluid simulation, particle systems, procedural generation, and post-processing pipelines. The skill is designed to accelerate shader development by providing structured, reusable techniques that can be combined and extended.

The skill operates through a simple invocation pattern, accepting natural language or technical requests and returning production-ready GLSL code. Whether you need a volumetric fog effect, a procedural terrain generator, or a physically based lighting model, Shader Dev translates your requirements into working shader code. It bridges the gap between conceptual visual goals and the precise mathematical implementations that GPU programming demands.

At its core, Shader Dev treats shader development as a unified discipline rather than a collection of isolated tricks. The techniques are organized to build on each other, allowing developers to compose complex visual systems from well-tested components. This approach reduces debugging time and encourages a deeper understanding of the underlying mathematics.

Who Should Use This

  • Graphics programmers who need rapid prototyping of visual effects without writing boilerplate GLSL from scratch
  • Game developers integrating custom shaders into Unity, Unreal, or WebGL pipelines
  • Creative coders working on generative art, live visuals, or interactive installations
  • Technical artists who understand visual goals but want assistance translating them into shader mathematics
  • Web developers building immersive WebGL or Three.js experiences that require custom rendering effects
  • Students and researchers learning GPU programming concepts through practical, working code examples

Why Use It?

Problems It Solves

  • Writing ray marching loops and SDF compositions from scratch is time-consuming and error-prone, requiring precise mathematical knowledge that Shader Dev encapsulates
  • Fluid and particle simulations involve complex numerical methods that are difficult to implement correctly without a structured reference
  • Post-processing effects such as bloom, depth of field, and chromatic aberration require careful framebuffer management that varies across environments
  • Procedural generation techniques like noise functions, domain warping, and fractal generation involve subtle implementation details that affect visual quality significantly
  • Debugging GLSL code is notoriously difficult due to limited tooling, making correct first-pass implementations especially valuable

Core Highlights

  • 36 ShaderToy-compatible GLSL techniques covering the full visual effects pipeline
  • Ray marching with configurable step counts, epsilon values, and maximum distance parameters
  • SDF primitive library including spheres, boxes, cylinders, tori, and boolean operations
  • Fluid simulation using advection, pressure solving, and vorticity confinement
  • Particle systems with GPU-side position and velocity integration
  • Procedural noise including Perlin, Simplex, Worley, and domain-warped variants
  • Physically based lighting with diffuse, specular, ambient occlusion, and shadow components
  • Post-processing stack including tone mapping, vignette, blur, and color grading

How to Use It?

Basic Usage

Invoke the skill with a descriptive request targeting your desired effect.

/shader-dev Create a ray marching scene with a sphere and soft shadows

/shader-dev Generate a fluid simulation shader with vorticity confinement

/shader-dev Write a procedural terrain using domain-warped Perlin noise

Specific Scenarios

Scenario 1: SDF Scene Composition When building a complex scene from geometric primitives, request specific SDF operations. The skill will generate union, subtraction, and intersection functions alongside smooth blending operators using the standard smin technique.

Scenario 2: Post-Processing Pipeline For a full post-processing stack, specify which effects you need in sequence. The skill will structure the passes correctly, ensuring tone mapping occurs after bloom accumulation and before gamma correction.

Scenario 3: Particle System on GPU Request a GPU particle system with a specified count and behavior. The skill will generate both the update and render passes, using texture-encoded position and velocity buffers compatible with ShaderToy's multi-pass architecture.

Real-World Examples

A generative artist used Shader Dev to build a fluid ink simulation for a live performance, combining fluid advection with procedural color injection to create organic flowing visuals rendered at 60 frames per second in a browser.

A game studio prototyped a volumetric cloud system by requesting a ray marching shader with density sampling from a 3D noise field, then adapted the output for their Unity HDRP pipeline within a single afternoon.

Important Notes

Requirements

  • A ShaderToy-compatible GLSL environment or a WebGL 2.0 capable browser for direct execution
  • Basic familiarity with GLSL syntax and the fragment shader execution model
  • Understanding of coordinate systems and vector mathematics for interpreting and modifying generated code
  • For multi-pass techniques such as fluid simulation, an environment that supports framebuffer objects or ShaderToy buffer passes
