<h1>[name]</h1>
<p class="desc">Creates a texture directly from raw data, width and height.</p>
<h2>Constructor</h2>
<h3>[name]( data, width, height, format, type, mapping, wrapS, wrapT, magFilter, minFilter, anisotropy )</h3>
<p>
The data argument must be an [link:https://developer.mozilla.org/en-US/docs/Web/API/ArrayBufferView ArrayBufferView].
Further parameters correspond to the properties inherited from [page:Texture], where both magFilter and minFilter default to THREE.NearestFilter. The properties flipY and generateMipmaps are intially set to false.
</p>
<p>
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). Similarly, THREE.RGBFormat specifies a format where only three values are used for each texel.<br />
For the packed types, THREE.UnsignedShort4444Type, THREE.UnsignedShort5551Type or THREE.UnsignedShort565Type, all color components of one texel can be addressed as bitfields within an integer element of a Uint16Array.<br />
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.
</p>
<h2>Example</h2>
<code>
// create a buffer with color data
var size = width * height;
var data = new Uint8Array( 3 * size );
var r = Math.floor( color.r * 255 );
var g = Math.floor( color.g * 255 );
var b = Math.floor( color.b * 255 );
for ( var i = 0; i < size; i ++ ) {
var stride = i * 3;
data[ stride ] = r;
data[ stride + 1 ] = g;
data[ stride + 2 ] = b;
}
// used the buffer to create a [name]
var texture = new THREE.DataTexture( data, width, height, THREE.RGBFormat );
</code>
