I have 3 points and 3 values . I want interpol it on a square ----------------------- | a | x-> | * | | | | | y | | | | | | b*---*c | v | | ----------------------- I want every thing that is in the square. The values are linear in the sqare. How can I found the "deltax" and the "deltay" for it ? Thanx for reply.

So sorry for the explanation I was late.

Thank you for your work !

Take the first one and imagine that I want all the square around the triangle. I have just the 3 corner of the triangle. Yes ?
It ''s the same think, but I need interpolate and extrapolate faster .

I think I completely misunderstood your problem

originally you had posted something like this

-----------------------|         a           |    x->|         *           |    |        / \          |    y|       /   \         |    ||     b*-----*c       |    v|                     |-----------------------

But I couldn''t see it as that.

This isn''t school work, is it?
