**3D Interpolation x,y,z -> f(x,y,z)**

[kidongee]

Hi All,

Basically, I need a UDF for 3D Interpolation.
I was able to make UDF for 2D Interpolation, but 3D is very difficult.

Scenario: I will have a table with X, Y, Z and appropriate value f(x,y,z). With given table, if I pick any number to X,Y,Z , then interpolated f(x,y,z) is generated.

I attached a file! so please have a look!

My table will be either Table 1 or Table 2 or anything else. Means, Range Y wouldn't be same, Interval wouldn't be same, etc.

Thank you in advance!

Chris

P.S
.pdf file might help you understanding mathematical concepts.

What would the answer be for your example?

Can you help me about UDF? VBA code...

[StephenR]

Not sure I follow it, hence asking for an illustration of expected results.

[kidongee]

nah, I don't need your help. After I provide everything that you need, you just ignored it.

God speed.

Chris - you've got a strange attitude.

Ironically, you have probably alienated the one person on this forum, shg, who could have rattled you off a solution.

Bye bye.
