Hello all,
Until now i've being using Irregular2dSets to creat small "rectangles"
where a flatfield shows the color behaviour, but now i've to introduce
Altitude to the system and instead of rectangles i must have cubes or
Irregular3dsets i thought.
For a Irregualr2dset you define 4 points and 4 color values in each
point and you have a "solid" rectangle, but i create a irregular3dset
with 8 points with eight color values in for the flatfield i get 4
points in space instead of a cube with color variation.
How can i get a cube?
Cheers,
Tiago Simoes
