com.ardor3d.math.Transform
Transform models a transformation in 3d space as: Y = M*X+T, with M being a Matrix3 and T is a Vector3. Generally M will be a rotation only matrix in which case it is represented by the matrix and scale fields as R*S, where S is a positive scale vector. For non-uniform scales and reflections, use setMatrix, which will consider M as being a general 3x3 matrix and disregard anything set in scale.
