I meant to bring this up several months ago but it's been very busy here and I only recently started using iPi DMC 2.0 again.

Anyway, the detail of the volume data seems 'chunkier' in 2.0 than it did back in 1.0, which can make it harder to see the shape of the body when zoomed in close up. Is this because I'm still using converted 1.0 data instead of new 2.0 captured data? (Sorry, I still haven't gotten around to capturing new data with 2.0 but will do so this week.)

Also, I think the new colors in 2.0 make it difficult to distinguish the actor/skeleton from the volume data. Attached are two screen caps to illustrate.

I also find the flickering yellow data distracting during tracking. Can we get the option to hide the yellow data? This data is not particularly helpful when tracking anyway.

Thanks for listening guys!

Because the same colors and values are used through, it's difficult to distinguish the actor and skeleton from the volume, making tracking edits more confusing/difficult than needed. Yellow data is distracting and not needed during tracking--hide from view option?

Up close, the detail of the volume looks especially chunky compared to 1.0 data, again, making it a little more difficult to see how close the track compares with the original motion.

For comparison, here's what similar data looked like back in 1.0. It's been a while since I did this in 1.0 but it seemed like this was easier to look at and work with.

Thank you for your opinion!
We already were thinking about making model and point cloud more contrast. Maybe, the model should be in uniform distinguishable color (say, yellow).
Regarding "chunkiness": maybe a setting for the scale of point cloud "points" would help.

This yellow areas are shown only on color plane, only when aligning of color to depth is enabled. The reason for this is to mark places where aligning color to depth could not be accomplished due to unknown depth. Otherwise, you would see distorted image instead - and I suppose it also would be annoying. To dismiss the yellow, you have choices of disabling alignment (View > Align Color Video To Depth), or hiding color plane completely.
