<h2>Code Example</h2>
|

|
|
|
||
|
|
<p>This creates a [name] with repeating data, 0 to 255</p>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
// create a buffer with some data
|
||
|
|
const sizeX = 64;
|
||
|
|
const sizeY = 64;
|
||
|
|
const sizeZ = 64;
|
||
|
|
|
||
|
|
const data = new Uint8Array( sizeX * sizeY * sizeZ );
|
||
|
|
let i = 0;
|
||
|
|
|
||
|
|
for ( let z = 0; z < sizeZ; z ++ ) {
|
||
|
|
for ( let y = 0; y < sizeY; y ++ ) {
|
||
|
|
for ( let x = 0; x < sizeX; x ++ ) {
|
||
|
|
data[ i ] = i % 256;
|
||
|
|
i ++;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
// use the buffer to create the texture
|
||
|
|
const texture = new THREE.Data3DTexture( data, sizeX, sizeY, sizeZ );
|
||
|
|
texture.needsUpdate = true;

<h2>Properties</h2>
|
||
|
|
|
||
|
|
<p>See the base [page:Texture Texture] class for common properties.</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean flipY]</h3>
|
||
|
|
<p>
|
||
|
|
Whether the texture is flipped along the Y axis when uploaded to the GPU.
|
||
|
|
Default is `false`.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean generateMipmaps]</h3>
|
||
|
|
<p>
|
||
|
|
Whether to generate mipmaps (if possible) for the texture. Default is
|
||
|
|
`false`.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Image image]</h3>
|
||
|
|
<p>
|
||
|
|
Overridden with a record type holding data, width and height and depth.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean isData3DTexture]</h3>
|
||
|
|
<p>Read-only flag to check if a given object is of type [name].</p>
|
||
|
|
|
||
|
|
<h3>[property:number magFilter]</h3>
|
||
|
|
<p>
|
||
|
|
How the texture is sampled when a texel covers more than one pixel. The
|
||
|
|
default is [page:Textures THREE.NearestFilter], which uses the value of
|
||
|
|
the closest texel.<br /><br />
|
||
|
|
|
||
|
|
See the [page:Textures texture constants] page for details.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:number minFilter]</h3>
|
||
|
|
<p>
|
||
|
|
How the texture is sampled when a texel covers less than one pixel. The
|
||
|
|
default is [page:Textures THREE.NearestFilter], which uses the value of
|
||
|
|
the closest texel.<br /><br />
|
||
|
|
|
||
|
|
See the [page:Textures texture constants] page for details.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:number unpackAlignment]</h3>
|
||
|
|
<p>
|
||
|
|
`1` 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
|
||
|
|
[link:https://registry.khronos.org/OpenGL-Refpages/es3.0/html/glPixelStorei.xhtml glPixelStorei] for more information.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:number wrapR]</h3>
|
||
|
|
<p>
|
||
|
|
This defines how the texture is wrapped in the depth direction.<br />
|
||
|
|
The default is [page:Textures THREE.ClampToEdgeWrapping], where the edge
|
||
|
|
is clamped to the outer edge texels. The other two choices are
|
||
|
|
[page:Textures THREE.RepeatWrapping] and [page:Textures THREE.MirroredRepeatWrapping].
|
||
|
|
See the [page:Textures texture constants] page for details.
