Perhaps this is already on the roadmap, but in case it isn't - it would be great if ColourSpace could create the fledgeling "Gamut rings" charts.

"At Display Week 2023, Dr. K. Masaoka demos software that is able to measure 600 patches and plot gamut rings in just sixty seconds."

I assume that really means "....software that is able to measure 600 patches and then, in just sixty seconds, plot gamut rings".

To me the volumetric view with Colourspace is exactly what this is but variable precision (depending on patches) and aslo able to show tangent lines for target vs measure. Maybe I'm missing something??

OK, so they use a 2D plot.

We cannot really see any benefit in a 2D plot attempting to show volumetric data (based on luminance), when we have full volumetric graphs already.
And 60 seconds to generate a graph plot...

But, we do plan on adding more graphs, so will likely add gamut rings, just because...
And then users will be able to see for themselves the restrictions/issue with them.

Ah, I can answer that. The benefit isn't just for users of ColourSpace, we of course can view the volumetric data in many nice ways as we have the software.

It's for sharing the data with other people who can't view the volumetric data and are not ColourSpace users, just like the Reports are for sharing the calibration data with other people, and that's surely why Reports were added. That's why I think it would be nice to add it, and it would be something ColourSpace could create very easily and other software can't, not that you need to engage in such "point scoring", CS speaks for itself, but it'd be another tick in the ColourSpace feature list in those comparison grids people make!

I thought it would be nice to be able to measure different displays, and create the gamut rings plots for each one, and share the output with other people. Sometimes, a feature benefits people who aren't users of the software as well as people who own the software, and this is one of those cases. Anyway hope that clarifies my reasoning.

Maybe for reports... but I still think a 3D graph is better in Reports.
Even a couple of different angles, as needed.
But as said, we are not saying no to adding new graphs...

Steve

Yes, I appreciate that. Thanks!

Mike, I may be wrong, but those "gamut rings" remind me of the "3D gamut" presentation CalMAN was ballyhooing a few years ago. I'm operating from an old man's memory here, so if I'm off a bit, be gentle.

If I remember correctly, the 3D Gamut program Calman made some noise about was an attempt to compete with the 3D graphs in ColourSpace, and was a very simple 3D viewer, with no actual useful graph info.
Seem to remember is was called something like 'ColorVolumerVisualiser'...?

Edit to add: found this old piccy...

This thread has resurfaced as a user just pointed out Calman's latest hyped bollox marketing video - this time for the implementation of Gamut Rings.
I've said before I really feel sorry for David who fronts the videos... anyway, it seems it just gets worse.

And as I've said before, we will get around to adding Gamut Rings to ColourSpace, just because why not...?
But as we already have have true Volumetric 3D Graphs it really is not a priority.
And more importantly - the data Gamut Rings represent is basically so limited as to be near useless.
(But it will important for people to be able to compare Gamut Rings to true Volumetric 3D graphs, to see just how inaccurate Gamut Rings graphs really are...)

Take the two images below for example.
You can clearly see the gamut reduction with low-light levels, as with CRTs, LCDs, QD-OLEDs.
(Basically most display technologies, other than OLEDs.)
And it is basically impossible to see such gamut issues with Gamut Rings.

The first image shows all volumetric points in the zoomed area, and if we plot just the Primary colours, we can see even clearer the actual gamut reduction, as in the second image.
And the Tangent lines make the plots very simple to visualise and simple to understand.

Additionally, the granularity of Gamut Rings (at least in the Calman iteration) is severely limited, and likely would not plot such a gamut reduction anyway.
The below 3D graphs plot each and every measurement, defining gamut and luma in true volumetric space, and targets the actual target colour space, defining exactly any associated calibration limitations.
Calman's 602 measurements are just not enough to define real volumetric data of any kind, including a true gamut coverage value.
(Although the value will be slightly better than a basic 2D value.)

Also, such true 3D volumetric graphs are available in all ColourSpace licenses, other than ZRO - not just the more expensive licenses, as with Calman's options.
I have to assume, as stated by someone else in a different forum, they are not in the lower Calman license levels as that would show the limitations of the calibration capabilities of those license levels...
