Any 3D geometry algorithms library in Java?

Question

I need a library, that could perform some geometry operations with objects in 3D, like: - Find min distance between 2 triangles - Intersect two polygons - Intersect to objects and exctract their difference (hardest one). Is there any such open-source library? P.S. JTS is not an option, because I doesn't work with 3D :(

Answer 1

I would recommend GeoRegression, seems to be what you're looking for.

Geometric Regression Library (GeoRegression) is an open source Java geometry library for scientific computing with a focus on 2D/3D space. GeoRegression provides the ability to estimate the closest point/distance between geometric primitives, best-fit shapes, and best fit geometric transform between sets of objects

Examples of shapes that can be defined, both 2D and 3D.

3D might be possible through some abstract means with this library, so I'd look into it, but it would be oblique as all get out.
