Map the UVW space in a trapezoid box

Hi!

I want to move a point around contained only inside a trapezoid-ish box with three slider between 0 and 1. Boxes of six surfaces, at least two of them parallel, top and bottom.

This means that as you move in w (z) direction the point will move in x or/and y while retaining its u and/or v - value.

I guess this is a very basic problem (?). But so far Ive been going at it the wrong way... Building my own functions and what not. Im thinking i should be able to rebuild the shape and use Evaluate Box to get the coordinates. But I can't.

Hi.

How about using "BoxMorph"?

Thank you very much! This solved it. I had been trying boxmorph a lot without getting it right actually - but i realize now that my "reference box" input was flawed. This saved me a lot of frustration and time, thanks again!
