Description

affine_trans_point_3daffine_trans_point_3dAffineTransPoint3dAffineTransPoint3dAffineTransPoint3daffine_trans_point_3d applies an arbitrary affine 3D transformation, i.e., scaling, rotation, and translation, to the input points (PxPxPxPxpxpx,PyPyPyPypypy,PzPzPzPzpzpz) and returns the resulting points in (QxQxQxQxqxqx, QyQyQyQyqyqy,QzQzQzQzqzqz). The affine transformation is described by the homogeneous transformation matrix given in HomMat3DHomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d. This corresponds to the following equation (input and output points as homogeneous vectors):

The transformation matrix can be created using the operators hom_mat3d_identityhom_mat3d_identityHomMat3dIdentityHomMat3dIdentityHomMat3dIdentityhom_mat3d_identity, hom_mat3d_scalehom_mat3d_scaleHomMat3dScaleHomMat3dScaleHomMat3dScalehom_mat3d_scale, hom_mat3d_rotatehom_mat3d_rotateHomMat3dRotateHomMat3dRotateHomMat3dRotatehom_mat3d_rotate, hom_mat3d_translatehom_mat3d_translateHomMat3dTranslateHomMat3dTranslateHomMat3dTranslatehom_mat3d_translate, etc., or be the result of pose_to_hom_mat3dpose_to_hom_mat3dPoseToHomMat3dPoseToHomMat3dPoseToHomMat3dpose_to_hom_mat3d.

For example, if HomMat3DHomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d corresponds to a rigid transformation, i.e., if it consists of a rotation and a translation, the points are transformed as follows:
