Pandora 3D Lut file format

Pandora 3D Lut files are ASCII text files with .m3d extension. They share the format with Pandora MegaGamma LUT files, with some fixed values to identify them as a 3D lut to Platinum.  To access files place them into /pogle/virtual, then click on the file in the Black Hole.  The Pixi, Data Revolution and standard dual board revolutions allow 17 point 3D cubes.  The CDL Daily system also allows 33-point cubes.

The file starts with a header that is used for identification in the Vault

Then the following items must be defined. 

channel, which is position in signal path.  For 3D luts, this must be 3D.

• channel 3d

in, defines the number of entries in the cube.  Each entry must have a separate line of data in the data section.

• in 4913 (17-point cube)
• in 35937 (33-point cube - Daily system only)

out, which is the size (range) of each entry.  For 3D cubes this should be 65536.

• out 65536 (16 bit)

format, whether the data is defined as a set of points or a lookup table.  For 3D cubes this must be lut.

• format lut

• values red green blue (index (values), then red, green and blue data)
• red green blue (red green and blue data - one line for each value without the preceeeding index)

• 17-point bypass example
