Hi,
In 3D you have the Surface-command. It would be highly useful to have something similar in 2D. That is a command
Region[<expression>,<expresion>,<parameter>,<min>,<max>,<parameter>,<min>,<max>]
The unit disc (with filling but without any boundary) could be drawn using:
Region[r*cos(v),r*sin(v),r,0,1,v,0,2*pi]
(I already know that there are easy ways to get the same picture but I just wanted an example to illustrate the syntax.)
I have no idea whether this will be easy or hard to do but I have great confidence in the developers as they have already amazed me numerous times before.
If It can be done it would make it a lot simpler to color regions in 2D.
Best regards,
Mikkel
