ShaderPass is an addon, and must be imported explicitly, see Installation#Addons.
import { ShaderPass } from 'three/addons/postprocessing/ShaderPass.js';Constructor
new ShaderPass( shader : Object | ShaderMaterial, textureID : string )
Constructs a new shader pass.
| shader |
A shader object holding vertex and fragment shader as well as defines and uniforms. It's also valid to pass a custom shader material. |
| textureID |
The name of the texture uniform that should sample the read buffer. Default is |
Properties
.material : ShaderMaterial
The pass material.
.textureID : string
The name of the texture uniform that should sample the read buffer.
Default is 'tDiffuse'.
.uniforms : Object
The pass uniforms.
Methods
.dispose()
Frees the GPU-related resources allocated by this instance. Call this method whenever the pass is no longer used in your app.
- Overrides: Pass#dispose
.render( renderer : WebGLRenderer, writeBuffer : WebGLRenderTarget, readBuffer : WebGLRenderTarget, deltaTime : number, maskActive : boolean )
Performs the shader pass.
| renderer |
The renderer. |
| writeBuffer |
The write buffer. This buffer is intended as the rendering destination for the pass. |
| readBuffer |
The read buffer. The pass can access the result from the previous pass from this buffer. |
| deltaTime |
The delta time in seconds. |
| maskActive |
Whether masking is active or not. |
