get height of point in a cube

[botanic]

I have 4 points that each are 64 x,y values apart with different Z values that are arranged like this with 90 degree angles:

0,0 64,0


0,64 64,64


Also inside that square there is a 5th value I only have the X and Y value of and need to find the Z value of.

If anyone has any ideas on how to solve this id greatly apreciate it I have been at this for hours...

With no known relationship between the original four points in the plane and the fifth point in three-space, I can't imagine how one might find the fifth points spatial coordinates. Sorry.

What's the problem with the Weighted Average you have already?

1) Calculate the distance from each corner to the interior point.
2) This is where you have to pick. 2a) Either subtract these distances from the maximum possible distance or 2b) simply find the reciprocals of the distances.
3) Multiply the respective weights by the known values, divide by the total of all waights, and you are done.

Of course, there is no substitute for a known relationship.

Note: Normally, it would be considered bad for to post the same problem in multiple locations. If you have a problem with a response you have received, simply ask for additional discussion. The hard part in this process is that if you are not getting the idea after some discussion, the difficulty may be with your abilities rather than with the response. In this case, seeking an additional repsonse would not be worthwhile until you have upgraded your math skills.
