Visualize Finite Dome?

wscottart

When this gets turned on the background gets all green and orange. With a box dome I get distinct color intersections . I'm curious is this just showing the intensities of the light source, whats is its purpose?  It appears to be a  function to help "visualize" the dome similiar to using a mirror ball.

Is this right or am I way off here?

It's to help with orientation and postion, yes.

Thank you

When first getting started I would turn that on and actually use it in my renders. In some cases it actually makes a neat backdrop. Nice to actaully figure out what its for and have that confirmed =).
