[page:Texture] →

[name]

Creates an array of textures directly from raw data, width and height and depth. This type of texture can only be used with a WebGL 2 rendering context.

Constructor

[name]( data, width, height, depth )

The data argument must be an [link:https://developer.mozilla.org/en-US/docs/Web/API/ArrayBufferView ArrayBufferView]. The properties inherited from [page:Texture] are the default, except magFilter and minFilter default to THREE.NearestFilter. The properties flipY and generateMipmaps are initially set to false.

The interpretation of the data depends on type and format: If the type is THREE.UnsignedByteType, a Uint8Array will be useful for addressing the texel data. If the format is THREE.RGBAFormat, data needs four values for one texel; Red, Green, Blue and Alpha (typically the opacity).
For the packed types, THREE.UnsignedShort4444Type and THREE.UnsignedShort5551Type all color components of one texel can be addressed as bitfields within an integer element of a Uint16Array.
In order to use the types THREE.FloatType and THREE.HalfFloatType, the WebGL implementation must support the respective extensions OES_texture_float and OES_texture_half_float. In order to use THREE.LinearFilter for component-wise, bilinear interpolation of the texels based on these types, the WebGL extensions OES_texture_float_linear or OES_texture_half_float_linear must also be present.

代码示例

This creates a [name] where each texture has a different color.

// create a buffer with color data const width = 512; const height = 512; const depth = 100; const size = width * height; const data = new Uint8Array( 4 * size * depth ); for ( let i = 0; i < depth; i ++ ) { const color = new THREE.Color( Math.random(), Math.random(), Math.random() ); const r = Math.floor( color.r * 255 ); const g = Math.floor( color.g * 255 ); const b = Math.floor( color.b * 255 ); for ( let j = 0; j < size; j ++ ) { const stride = ( i * size + j ) * 4; data[ stride ] = r; data[ stride + 1 ] = g; data[ stride + 2 ] = b; data[ stride + 3 ] = 255; } } // used the buffer to create a [name] const texture = new THREE.DataArrayTexture( data, width, height, depth ); texture.needsUpdate = true;
