The majority of us use a mouse because it's actually easier than using a drawing tablet. I have a perfectly good large Intuos Pro, but I never use it with CC3 because mouse is better.

However, I get what you are saying since there are users who cannot use a mouse, though I am out of my depth regarding any kind of alternatives - not being a coder myself.

I gave in to temptation and warped a copy of the inner crater to the new grid. Looks like I also still have craters on the brain.

Oh well, I might as well carry on...

Here's a preview of the form using just the shading.

We have craters now :)

It's likely that ancient cartographers had a tendency to make the country their commissioner was lord over look bigger than it really was. Flattery goes a long way when there's no proof that things are otherwise and you might be executed for making it look smaller than the last cartographer did.

Can't do that today, of course - except by changing the projection. I have always wondered why each country hasn't produced their own hemispherical projection with the heart of their own country at the centre.
