Equation rect to plane

whats calculate this place help me!!

Can you please explain better what you want.

Sorry but this doesn't make any sense.

I think he wants the nx,ny,nz,d values based off of a rectangle,where it intersects some of its points?

It would make much more since to calculate it base on a quad or a triangle.

you can get a lot of information out of that question!

excused my not good English

i have created the new topic for question
