The reason I said roll isn't counted is because I meant rolling the pen along the long axis (like the way it would roll off of a table)[1] - that I presume isn't being tracked? (If you hold its orientation and pressure and location of tip constant, but kind of roll it between your fingers, that wouldn't cause a detectable change would it?)

Is that what musesum meant though by 5 axes? namely x/y on the screen, pressure on the screen, and 2 of the 3 of pitch, roll, and yaw?....

translated to cartesian coordinates. position x, y; tilt x, y; and pressure. No yaw, which would be twisting the pencil.

There's also twisting (yes, it's a true 5 axis). But you have to buy the more expensive "art pen". See: https://www.wacom.com/en-us/store/pens/art-pen

Notably, some pens support additional pressure axes (for example, the "brush pen"). These are general-purpose sensors can be mapped freely.

I'm not aware though of any pen that supports truly 6 axes, but I suspect it's not a technical limitation.

[edit] I actually dislike the art pen because of the way it's handled: it's too fat.

Thanks. Didn't realize Wacom had one of these - has been a while. Yeah, I preferred the thinner "classic pen" https://www.wacom.com/en-us/store/pens/classic-pen

One trick is to use the eraser as a tip and to cover the tablet with a neoprene skin stretched tight. The result is a really light and spongy stroke. Has a very sensual feel.

Have you have ever used the "flex" nib? I wonder if anyone found some "use" out of it that couldn't be done by just pressure feel adjustment.

> Have you have ever used the "flex" nib?

Tried it once. I suspect that if you spent thousands of hours drawing that the haptics would make a difference.

thanks - what you call yaw I called roll, by analogy with the shape of a pencil versus airplane.
