BlurPass
Extends:
Indirect Implements:
An efficient, incremental blur pass.
Note: This pass allows the input and output buffer to be the same.

The current resolution scale. |
Method Summary
Public Methods | ||
public |
Returns the current resolution scale. |
|
public |
initialize(renderer: WebGLRenderer, alpha: Boolean) Performs initialization tasks. |
|
public |
render(renderer: WebGLRenderer, inputBuffer: WebGLRenderTarget, outputBuffer: WebGLRenderTarget, delta: Number, stencilTest: Boolean) Blurs the input buffer and writes the result to the output buffer. |
|
public |
setResolutionScale(scale: Number) Sets the resolution scale. |
|
public |
Updates the size of this pass. |
Inherited Summary

public |
[key]: * |
|
public |
Indicates whether this pass should be executed. |
|
public |
The name of this pass. |
|
public |
Indicates whether the EffectComposer should prepare a depth texture for this pass. |
|
public |
Indicates whether the EffectComposer should swap the frame buffers after this pass has finished rendering. |
|
public |
Indicates whether this pass should render to screen. |
|
protected |
camera: Camera The camera. |
|
protected |
scene: Scene The scene to render. |
|
private |
quad: Mesh A quad mesh that fills the screen. |
|
public |
dispose() Performs a shallow search for disposable properties and deletes them. |
|
public |
getDepthTexture(): Texture Returns the current depth texture. |
|
public |
getFullscreenMaterial(): Material Returns the current fullscreen material. |
|
public |
initialize(renderer: WebGLRenderer, alpha: Boolean) Performs initialization tasks. |
|
public abstract |
render(renderer: WebGLRenderer, inputBuffer: WebGLRenderTarget, outputBuffer: WebGLRenderTarget, delta: Number, stencilTest: Boolean) Renders the effect. |
|
public |
setDepthTexture(depthTexture: Texture, depthPacking: Number) Sets the depth texture. |
|
public |
Updates this pass with the renderer's size. You may override this method in case you want to be informed about the main render size. The EffectComposer calls this method before this pass is initialized and every time its own size is updated. |
|
protected |
setFullscreenMaterial(material: Material) Sets the fullscreen material. |

Public Methods
public initialize(renderer: WebGLRenderer, alpha: Boolean) source
Performs initialization tasks.
Override:
Pass#initializeParams:
Name | Type | Attribute | Description |
renderer | WebGLRenderer | The renderer. |
|
alpha | Boolean | Whether the renderer uses the alpha channel or not. |
public render(renderer: WebGLRenderer, inputBuffer: WebGLRenderTarget, outputBuffer: WebGLRenderTarget, delta: Number, stencilTest: Boolean) source
Blurs the input buffer and writes the result to the output buffer. The input buffer remains intact, unless its also the output buffer.
Override:
Pass#renderParams:
Name | Type | Attribute | Description |
renderer | WebGLRenderer | The renderer. |
|
inputBuffer | WebGLRenderTarget | A frame buffer that contains the result of the previous pass. |
|
outputBuffer | WebGLRenderTarget | A frame buffer that serves as the output render target unless this pass renders to screen. |
|
delta | Number |
|
The time between the last frame and the current one in seconds. |
stencilTest | Boolean |
|
Indicates whether a stencil mask is active. |
