Category Shaders

What is a Shader?

A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them.

Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). This page is all about these "real-time" shaders, which are optimized to render efficiently, trading performance for less accuracy. "Offline" shaders are used with non-real-time renderers, like mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).

Advanced Tutorials

Tools

To create and edit shaders, most people use a text editor (like Notepad ++) to write them and a 3d program (a game engine, 3ds Max, Maya, etc.) to view them. For those who are new to shaders the following tools provide a graphical user interface for easier creation.

  • FX Composer is NVIDIA's shader authoring toolset.
  • GLSL Hacker "is a cross-platform (Windows, Linux and OS X) tool for fast realtime 3D prototyping and coding. It's based on widely used standards such as GLSL (OpenGL Shading Language), Lua or Python. GLSL Hacker has been designed for developers (from newbies to confirmed) and technical 3D artists."
  • GLSL Sandbox is a browser-based code editor that shows the output live, right there behind your code. Also has a gallery of neat tricks to steal (ahem, borrow) from.
  • mental mill Standard Edition "allows the user to write and edit shader code, and visually debug the shader by interactively inspecting variables while stepping through the code." The more limited Artist Edition is free for personal use, and came bundled with 3ds Max 2010.
  • PowerVR SDK lets you live-edit and gives you rough estimates on shader costs. Helps with optimising GL ES2.0 shaders. Works with regular GLSL, too.
  • RenderMonkey is AMD's shader authoring toolset.

Shader Tools for 3ds Max

  • 3Point Shader Pro "is a toolset for creation and presentation of high-quality real- time materials in the Autodesk 3ds Max™ viewport."
  • Shader FX "is a full-featured real-time shader editor for 3ds Max that allows artists with no previous programming experience to build complex HLSL or CG FX shaders, using a graphical schematic interface to wire nodes together." No longer being developed

Shader Tools for Maya

Shader Tools for Unity

  • Shader Forge "The goal with Shader Forge is to provide an intuitive and visual way of creating shaders in the Unity engine, just like the Material Editor in UDK."
  • ShaderFusion is a node-based shader editor for Unity.
  • Strumpy Shader Editor another node-based shader editor for Unity.

Shader Tools for Unreal Engine
