ColorDepthEffect

Extends:

three~EventDispatcher → Effect → ColorDepthEffect

Indirect Implements:

A color depth effect.

Simulates a hardware limitation to create a retro feel. The real color depth remains unchanged.

Public Constructors

public constructor(options: Object) source

Constructs a new color depth effect.

Override:

Effect#constructor

Params:

Name	Type	Attribute	Description
options	Object	optional	The options.
options.blendFunction	BlendFunction	optional	The blend function of this effect.
options.bits	Number	optional default: 16	The color bit depth.

Public Members

public get bitDepth: Number source

The virtual amount of color bits.

Each color channel effectively uses a fourth of the total amount of bits. Alpha remains unaffected.

public set bitDepth source

Public Methods

Returns the current color bit depth.

Return:

Number

The bit depth.

public setBitDepth(value: Number) source

Sets the virtual amount of color bits.

Params:

Name	Type	Attribute	Description
value	Number		The bit depth.
