I have a set of points in 3d space and I want to be able to categorize the shape that best fits them - cube, sphere, cylinder, planar (flat) etc.

I've looked at supervised/machine learning but since I need first generate a large training data set that's not really suitable.

My dream solution would be a java library with a wonderful magical function something like :

public enum ShapeType {
    CUBE,
    SPHERE,
    CYLINDER,
    PLANAR
}

public ShapeType CategorizeShapeFromPoints( 3DPoint[] points )

However, any and all help will be appreciated. Thanks

GLSL check if fragment is on geometry

as seen on Stack Overflow - Search for 'Stack Overflow'
I am currently writing the positions of my geometry to the RGB channels of gl_FragColor and I would like to write 1.0 to the alpha channel if the fragment is part of geometry, and 0.0 if its empty. Is there a simple way to tell if a fragment is geometry or not? Maybe through gl_FragCoord.z? thanks >>> More
