# LUT3D

The LUT3D element specifies a 3D LUT to apply.

## Contains

In order:

- Description. Optional, any number.
- Array (LUT3D). Required, one only.

NoteThe IndexMap element is not supported. The most efficient way to achieve the same result is to precede the operator with a LUT1D element.

## Contained By

- ProcessList

## Attributes

id, name, inBitDepth, outBitDepth
  See Common Operator Attributes.
interpolation
  Supported values are "trilinear" and "tetrahedral".

  This attribute is optional. If it is not specified, the default is "trilinear".

#### Topics in this section

- Array (LUT3D)

  The Array element specifies an array of values for a LUT or matrix. When it is contained by a LUT3D element, the format of its contents is different than when it is contained by LUT1D or Matrix elements.
