Three.js Documentation and Shader Learning Path

Based on the official Three.js documentation available, you're correct that there isn't specific information about nodes in the main documentation sections I can see. The documentation focuses on core aspects of Three.js including installation, scene creation, materials, and various other fundamental topics.

For learning shaders in Three.js, here are some recommendations:

Getting Started with Shaders

1. First, understand the basics of Three.js by following the official documentation:

   • Installation
   • Creating a scene
   • Working with materials (particularly ShaderMaterial)

2. For shader development specifically, you might want to explore:

   • The ShaderMaterial documentation
   • Matrix transformations
   • Post-processing techniques

Learning Path for Shaders

If you're deciding between nodes or TSL (Three.js Shader Language), consider that:

• Traditional GLSL shaders using ShaderMaterial are well-established and widely used
• Learning the fundamentals of shader programming with GLSL will give you a solid foundation regardless of which higher-level abstraction you might use later

The documentation doesn't explicitly state why nodes aren't covered, but this might be because they're either:

• A newer feature
• Considered an advanced topic
• Part of an experimental API
• Covered in separate documentation

Recommended Resources

Based on the documentation structure, I would recommend:

1. Start with the core Three.js concepts in the "Getting Started" section

2. Move to "Next Steps" particularly focusing on:

   • Post-processing
   • Matrix transformations
   • Color management

3. Explore the ShaderMaterial documentation for direct shader implementation

For the most current information on nodes or TSL, you might need to check the Three.js GitHub repository, forums, or third-party tutorials as they may not be fully integrated into the main documentation yet.
