I'm making a terrain editor, and i want tools similar tools those used in Sim City and The Sims. Right now you can only edit heights using spinners, one vertex at a time... very tedious. Can i use selection mode for individual vertices on a triangle strip? or would i have to draw a point at each vertex, and use those for selection mode? would a point even work very well, being so small?

it seems, after reading some other posts, that the glUnproject method for picking is prefered. agree/disagree? pro's/con's?
