Hello, Yes, Apache Commons Maths has what you need. Start by having a look at the org.apache.commons.math3.geometry.euclidean.threed package and the Vector3D class https://commons.apache.org/proper/commons-math/userguide/geometry.html
By the way, I have understand that this geometry package will be supplanted by the apache commons geometry (https://commons.apache.org/proper/commons-geometry/) but there is no release yet. Does anybody knows what is the associated schedule?
