45/** @class lass::prim::impl::Plane3DParametric
46 * @brief implementation of lass::prim::Plane3D with a parametric equation
47 * @author Bram de Greve [BdG]
48 *
49 * This implementation of the plane uses the parametric equation P(u, v) = S + u * U + v * V.
50 * with S a support point, U and V two direction vectors, and u and v two parameters.
51 *
52 * @warning currently, the plane will not automatically orthonormalize the direction vectors.
53 * There is a normalizing policy, but that's only for normalizing vectors, not for
54 * orthogonalizing two direction vectors. IF SOMEONE IS USING THIS PARAMETRIC PLANE
55 * CLASS AND RUNS IN SOME TROUBLES ON THIS, PLEASE CONTACT ME SO WE CAN WORK OUT
56 * A SOLUTION. Bram de Greve.
