new AfterimagePass( damp : number )
Constructs a new after image pass.
| damp |
The damping intensity. A higher value means a stronger after image effect. Default is |
Properties
.compFsMaterial : ShaderMaterial
The composition material.
.copyFsMaterial : ShaderMaterial
The copy material.
.damp : number
The damping intensity, from 0.0 to 1.0. A higher value means a stronger after image effect.
.uniforms : Object
The pass uniforms. Use this object if you want to update the
damp value at runtime.
pass.uniforms.damp.value = 0.9;
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 after image 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. |
- Overrides: Pass#render
.setSize( width : number, height : number )
Sets the size of the pass.
| width |
The width to set. |
| height |
