Simplest Linear interpolation:
f(x) = x1 + (abs(x2 - x1) / 2) (given x1 < x2) - the abs() is the absolute function (x>0) just in case you want to skip checking x1<x2)
but here is a web page that describes another approach which is more formal and probably
more correct for other applications where time is involved for example...

There are other formulas to calculate the bezier
points. I'll check my files to see if I find them.

Can you give us an example of this linear
interpolation?
By the way jbv, you made a demostration of openGL
in MetaCard. Are you going to keep working in
this demo? or Abandoned the idea?
