Custom Effects Using THREE.ShaderPass
Explore how to use THREE.ShaderPass in Three.js to create custom postprocessing effects. Learn about various built-in shaders including brightness, blur, edge detection, and color effects, and how to apply them to enhance your 3D scenes. This lesson provides practical examples and explains how to experiment with shader properties to achieve dynamic visual styles.
We'll cover the following...
We’ve used the standard passes provided by Three.js for our effects. Three.js also provides THREE.ShaderPass, which can be used for custom effects and comes with a large number of shaders that we can use and experiment with.
Using THREE.ShaderPass for custom effects
With THREE.ShaderPass, we can apply a large number of additional effects to our scene by passing in a custom shader. Three.js comes with a set of shaders that can be used together with this THREE.ShaderPass. They will be listed in this section. We’ve divided this lesson into three parts.
The first set involves simple shaders. All these shaders can be viewed and configured by opening up the shaders.js example (in the below playground):
BleachBypassShader: This creates a bleach bypass effect. With this effect, a silver-like overlay will be ...
