Does anyone know how I would determine if a certain point in space falls on the plane of a polygon?  Is there an SDK function for this?

Wishful thinking I'm sure but I fiugured I'd ask.

Hi,

there's lots of resources about that on the net, just search for point poly intersect / point plane intersect.

I am looking for this in google but I am not finding a specific page that discusses point/polygon intersection.  I see a lot that discusses line/plane intersection.  Is this the same idea?

okay so I got a formula for determining the distance of a point from a plane..   which looks like this

D = |ax0 + by0 + cz0 + d|

I am wondering how do I determine the numbers needed for the plane which is the numerator in this equation.

Anyone have any idea?
