Can any one please provide me with a ISO - Contour plotting algorithm. To

read a set of numeric values and plot contours with values indicated on

each contour line.

Thanks

The marching cubes algorithm will do. Or the delauney algorithm.

All depends how your data is 'organised'. If you have scattered data ofQuote:> Can any one please provide me with a ISO - Contour plotting algorithm. To

a 3D surface(x, y, Z), then you will have to apply a triangulation to

your data set and find the intersection of each contour plane with each

triangular plane. if your data is arranged as a 2d matrix representing

your surface, then consider four points at a time, divide them into four

triangles and find the intersection with each contour plane to get a

contour line.

If you want code to do the triangulation, e-mail me and I'll send you a

copy.
