The following shows an example of a 3D LUT XML file (value pairs in

<LUT3D> The root element/base tag that includes the other el-
ements and tags. It should provide the following at-
tributes:
name The name of the 3D LUT file.
N The number of nodes, i.e. 17.
BitDepth The bit depth of the 3D LUT file.
<values> Child element/tag that contains the R’G’B’ output
values for the RGB nodes. Each line consists of three
values (R’G’B’). The separation is made by spaces.
You have to define all 17
3
× 3 values and the triplets
have to be in ascending order. The values have to be
stated according to the bit depth.
