What it does

Wagner is a effects composer for three.js that allows you to create complex visual effects by combining multiple passes and shaders in a flexible and efficient way.

When to use it
  • •When you need to create custom, high-quality visual effects for your 3D application
  • •When you want to combine multiple shaders and passes to achieve a specific visual style
  • •When you need to optimize your rendering pipeline for better performance
Ready-to-paste prompt
Create a simple bloom effect: `const bloomPass = new Wagner.BloomPass(); composer.pass( bloomPass );`
Heads up: Wagner requires three.js to be installed and imported in your project, and the canvas element must be properly set up and referenced in the Wagner constructor
