Re: Interpolate 2D on irregular grid


Hi David

    I have made this test:

Interpolation[RandomReal[1, {100, 3}], InterpolationOrder -> All];
ContourPlot[%[x, y], {x, 0, 1}, {y, 0, 1}]
DensityPlot[%%[x, y], {x, 0, 1}, {y, 0, 1}]

And it worked well. I'm using Mathematica 8.
(it look like some strange Art!.. it's fun..)
best regards
Murta
