Dynamically create thousands of clickable pixels

Just a question
Is it possible to create a 3d circle or image/four sides with a million clickable pixels or more?

If so…

if you click one, can there be a cordinating click? Meaning click one and try to find the other.

A final may include a 3d rendering… but is the senerio possible?

If you know…

If you can point me in the right direction or a “YEAH it can be done LOOK”.

Or if you can do it personally email me.
