Need algortihm for processing a 3D-surface


Recommended Posts

I have some data that has been through the griddata function (1D-X, 1D-Y, 2D-Z).

The data is essentially a cone shape, and I am looking for a way to find the largest oval (and by extension, circle) that can be inscribed into that cone at any given level.

(modeling the cone will not work, the data is not regular enough).

Anyone know a good way? I am currently using a brute-force method which essentially spins around the axis looking for the largest X*Y distance.

What's about this: Take any data point and contruct a cone. Now throw away all data points which are outside the cone. Repeat until one data point remains. It gives the largest cone inside the data. But the requirement is that you know the axis and its direction.

Or do you need to find the direction as well?
