What I did, was to run
countour(..,save=T,..)
Save contour matrix and then invert coordinates to triangular grid
(linear transformation). I belive it is not most efficient way to do
it, but simlest one. I even started to write a function which would
plot it aftomaticaly, but it still have number of bugs. I need to unbug
it anyway, and then I will post it somewere.
