Variable (i.e per levels) cube and RGBCMY patch generator

In order to facilitate generation of characterisation of optimised patch-set I have generated a program allowing for:
  • Generating patches on interval levels (e.g. having from 0 to 50% a 10-cube size and from 50% to 100% a 15-cube size
  • For each level different cube size can be defined for each primary colour
  • Allowing a power value to be applied on the whole patch-set on for each primary colour
  • Allowing extra RGBCMY to be generated (still on the whole patch-set)
  • Converting the generated patch to be converted to any patch scale / resolution

In alternative, an RGBCMY based patch-set, also based on levels and allowing power value to be applied.
Those patches are generated so that can be recognised by Colourspace a ramp+
In addition, at the end of the patch generation, Oled patch sorting (a little variance of SOF08) can be run.

I would have liked to post here the executable, but the limit of 5MB for xip (I have 5.2) has stopped me.

Here an example of a cube built with 4 levels (cube size = 5) on the Red axis, 5 on the Green one and 6 one the Blue one:
5-6-7 cube on R-G-B

Here another example:
21 cube up to L50 and 10 up to L100

Also remember there is a Env. Variable that can be used to increase the Quick Profile patch limits.
All now inbuilt in ColourSpace options.

Inserted in last version (see here)
VPG2.8
Added Body Centric patches generation
Now extra WRGBCMY patches are defined for level
Added extra Grey Scale patches (still per level)
Added recovering on GS patches lost to asymmetric cube (indeed parallelepiped) generated with different RGB densities
Added defaults inherited from the previous levels (for a smoother patch generation process)
SOFS9.5
Added indicators of the patch leveraging process
Added a way to abort the patch leveraging process
Added indication of the patch leveraging process execution time

What is the difference between VPG & SOFS?
I am a bit confused.
