描述

projective_trans_point_3dprojective_trans_point_3dProjectiveTransPoint3dProjectiveTransPoint3dProjectiveTransPoint3dprojective_trans_point_3d applies the homogeneous projective transformation matrix HomMat3DHomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d to all input points (PxPxPxPxpxpx,PyPyPyPypypy,PzPzPzPzpzpz) and returns an array of output points (QxQxQxQxqxqx,QyQyQyQyqyqy,QzQzQzQzqzqz). The transformation is described by the homogeneous transformation matrix given in HomMat3DHomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d. This corresponds to the following equations (input and output points as homogeneous vectors):
