denser mesh for displacement

How does one add geometry/densness to an object created in sketchup?

Take a plane for example.
After its been created, how do I controll the amount of triangles it contains in order for the displacement map to have something to work with.

Thankfull for answers!

You could use the sandbox tool - it got a function “Add Detail”.

Thank You!
I heard you can create a grid over a plane in sketchup to add the wanted geometry?
Anybody who knows where I can can acces this grid pattern for planes?
