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):
projective_trans_point_3dprojective_trans_point_3dProjectiveTransPoint3dProjectiveTransPoint3dProjectiveTransPoint3dprojective_trans_point_3d then transforms the homogeneous
coordinates to Euclidean coordinates by dividing them by Tw:
If a point in the plane at infinity (Tw = 0) is created by the
transformation, an error is returned. If this is undesired,
