DepthDownsamplingPass

Extends:

Pass → DepthDownsamplingPass

Indirect Implements:

A pass that downsamples the scene depth by picking the most representative depth in 2x2 texel neighborhoods. If a normal buffer is provided, the corresponding normals will be stored as well.

This pass requires FloatType texture support.

Public Constructors

public constructor(options: Object) source

Constructs a new depth downsampling pass.

Override:

Pass#constructor

Params:

Name	Type	Attribute	Description
options	Object	optional	The options.
options.normalBuffer	Texture	optional default: null	A texture that contains view space normals. See NormalPass.
options.resolutionScale	Number	optional default: 0.5	The resolution scale.
options.resolutionX	Number	optional default: Resolution.AUTO_SIZE	The horizontal resolution.
options.resolutionY	Number	optional default: Resolution.AUTO_SIZE	The vertical resolution.
options.width	Number	optional default: Resolution.AUTO_SIZE	Deprecated. Use resolutionX instead.
options.height	Number	optional default: Resolution.AUTO_SIZE	Deprecated. Use resolutionY instead.

Public Members

public fullscreenMaterial: * source

The fullscreen material.

Override:

Pass#fullscreenMaterial

public needsDepthTexture: boolean source

Only relevant for subclassing.

Indicates whether the EffectComposer should prepare a depth texture for this pass. Set this to true if this pass relies on depth information from a preceding RenderPass.

Override:

Pass#needsDepthTexture

public needsSwap: boolean source

Only relevant for subclassing.

Indicates whether the EffectComposer should swap the frame buffers after this pass has finished rendering. Set this to false if this pass doesn't render to the output buffer or the screen. Otherwise, the contents of the input buffer will be lost.

Override:

Pass#needsSwap

public renderTarget: WebGLRenderTarget source

A render target that contains the downsampled normals and depth.

Normals are stored as RGB and depth as alpha.

public get texture: Texture source

The normal(RGB) + depth(A) texture.

Public Methods

public getResolution(): Resolution source

this method was deprecated. Use resolution instead.

Returns the resolution settings.

Return:

Resolution

The resolution.

public getTexture(): Texture source

this method was deprecated. Use texture instead.

Returns the normal(RGB) + depth(A) texture.

Return:

Texture

The texture.

public initialize(renderer: WebGLRenderer, alpha: Boolean, frameBufferType: Number) source

Override:

Pass#initialize

Params:
