Texture

Create a texture to apply to a surface or as a reflection or refraction map.

Note: After the initial use of a texture, its dimensions, format, and type cannot be changed. Instead, call .dispose() on the texture and instantiate a new one.

Code Example

// load a texture, set wrap mode to repeat

const texture = new THREE.TextureLoader().load( "textures/water.jpg" );

texture.wrapS = THREE.RepeatWrapping;

texture.wrapT = THREE.RepeatWrapping;

texture.repeat.set( 4, 4 );

Constructor

Texture( image, mapping, wrapS, wrapT, magFilter, minFilter, format, type, anisotropy, colorSpace )

Properties

.id : Integer

Readonly – unique number for this texture instance.

.isTexture : Boolean

Read-only flag to check if a given object is of type Texture.

.uuid : String

UUID of this object instance. This gets automatically assigned, so this shouldn’t be edited.

.name : String

Optional name of the object (doesn’t need to be unique). Default is an empty string.

.image : Image

An image object, typically created using the TextureLoader.load method. This can be any image (e.g., PNG, JPG, GIF, DDS) or video (e.g., MP4, OGG/OGV) type supported by three.js.

To use video as a texture you need to have a playing HTML5 video element as a source for your texture image and continuously update this texture as long as video is playing – the VideoTexture class handles this automatically.

.mipmaps : Array

Array of user-specified mipmaps (optional).

.mapping : number

How the image is applied to the object. An object type of THREE.UVMapping is the default, where the U,V coordinates are used to apply the map.

See the texture constants page for other mapping types.

.channel : Integer

Lets you select the uv attribute to map the texture to. 0 for uv1 for uv12 for uv2 and 3 for uv3.

.wrapS : number

This defines how the texture is wrapped horizontally and corresponds to U in UV mapping.

The default is THREE.ClampToEdgeWrapping, where the edge is clamped to the outer edge texels. The other two choices are THREE.RepeatWrapping and THREE.MirroredRepeatWrapping. See the texture constants page for details.

.wrapT : number

This defines how the texture is wrapped vertically and corresponds to V in UV mapping.

The same choices are available as for .wrapS : number.

NOTE: tiling of images in textures only functions if image dimensions are powers of two (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, …) in terms of pixels. Individual dimensions need not be equal, but each must be a power of two. This is a limitation of WebGL, not three.js.

.magFilter : number

How the texture is sampled when a texel covers more than one pixel. The default is THREE.LinearFilter, which takes the four closest texels and bilinearly interpolates among them. The other option is THREE.NearestFilter, which uses the value of the closest texel.

See the texture constants page for details.

.minFilter : number

How the texture is sampled when a texel covers less than one pixel. The default is THREE.LinearMipmapLinearFilter, which uses mipmapping and a trilinear filter.

See the texture constants page for all possible choices.

.anisotropy : number

The number of samples taken along the axis through the pixel that has the highest density of texels. By default, this value is 1. A higher value gives a less blurry result than a basic mipmap, at the cost of more texture samples being used. Use renderer.capabilities.getMaxAnisotropy() to find the maximum valid anisotropy value for the GPU; this value is usually a power of 2.

.format : number

The default is THREE.RGBAFormat.

See the texture constants page for details of other formats.

.internalFormat : String

The default value is obtained using a combination of .format and .type.

The GPU format allows the developer to specify how the data is going to be stored on the GPU.

See the texture constants page for details regarding all supported internal formats.

.type : number

This must correspond to the .format. The default is THREE.UnsignedByteType, which will be used for most texture formats.

See the texture constants page for details of other formats.

.offset : Vector2

How much a single repetition of the texture is offset from the beginning, in each direction U and V. Typical range is 0.0 to 1.0.

.repeat : Vector2

How many times the texture is repeated across the surface, in each direction U and V. If repeat is set greater than 1 in either direction, the corresponding Wrap parameter should also be set to THREE.RepeatWrapping or THREE.MirroredRepeatWrapping to achieve the desired tiling effect.

.rotation : number

How much the texture is rotated around the center point, in radians. Positive values are counter-clockwise. Default is 0.

.center : Vector2

The point around which rotation occurs. A value of (0.5, 0.5) corresponds to the center of the texture. Default is (0, 0), the lower left.

.matrixAutoUpdate : Boolean

Whether to update the texture’s uv-transform .matrix from the texture properties .offset.repeat.rotation, and .center. True by default. Set this to false if you are specifying the uv-transform matrix directly.

.matrix : Matrix3

The uv-transform matrix for the texture. Updated by the renderer from the texture properties .offset.repeat.rotation, and .center when the texture’s .matrixAutoUpdate property is true. When .matrixAutoUpdate property is false, this matrix may be set manually. Default is the identity matrix.

.generateMipmaps : Boolean

Whether to generate mipmaps (if possible) for a texture. True by default. Set this to false if you are creating mipmaps manually.

.premultiplyAlpha : Boolean

If set to true, the alpha channel, if present, is multiplied into the color channels when the texture is uploaded to the GPU. Default is false.

Note that this property has no effect for ImageBitmap. You need to configure on bitmap creation instead. See ImageBitmapLoader.

.flipY : Boolean

If set to true, the texture is flipped along the vertical axis when uploaded to the GPU. Default is true.

Note that this property has no effect for ImageBitmap. You need to configure on bitmap creation instead. See ImageBitmapLoader.

.unpackAlignment : number

4 by default. Specifies the alignment requirements for the start of each pixel row in memory. The allowable values are 1 (byte-alignment), 2 (rows aligned to even-numbered bytes), 4 (word-alignment), and 8 (rows start on double-word boundaries). See glPixelStorei for more information.

.colorSpace : string

THREE.NoColorSpace is the default. Textures containing color data should be annotated with THREE.SRGBColorSpace or THREE.LinearSRGBColorSpace.

.version : Integer

This starts at 0 and counts how many times .needsUpdate is set to true.

.onUpdate : Function

A callback function, called when the texture is updated (e.g., when needsUpdate has been set to true and then the texture is used).

.needsUpdate : Boolean

Set this to true to trigger an update next time the texture is used. Particularly important for setting the wrap mode.

.userData : Object

An object that can be used to store custom data about the texture. It should not hold references to functions as these will not be cloned. Default is an empty object {}.

.source : Source

The data definition of a texture. A reference to the data source can be shared across textures. This is often useful in context of spritesheets where multiple textures render the same data but with different texture transformations.

Methods

EventDispatcher methods are available on this class.

.updateMatrix () : undefined

Update the texture’s uv-transform .matrix from the texture properties .offset.repeat.rotation, and .center.

.clone () : Texture

Make copy of the texture. Note this is not a “deep copy”, the image is shared. Besides, cloning a texture does not automatically mark it for a texture upload. You have to set .needsUpdate to true as soon as its image property (the data source) is fully loaded or ready.

.toJSON ( meta : Object ) : Object

meta — optional object containing metadata.

Convert the texture to three.js JSON Object/Scene format.

.dispose () : undefined

Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.

.transformUv ( uv : Vector2 ) : Vector2

Transform the uv based on the value of this texture’s .offset.repeat.wrapS.wrapT and .flipY properties.
