void Affine3DTransform::SetRotationX (  float  theta, const Vect3Df &  center = Vect3Df(0, 0, 0) )

Set rotation around line passing through C and parallel to X Axis, The rotation will be set absolutely, to allow more sophisticated rotation use concatenate several Affine3DTransforms using the *= operator as in: Affine3DTransform Ax; Ax.SetRotationX(phiX); Affine3DTransform Ay; Ay.SetRotationX(phiY); Ax*=Ay; Definition at line 124 of file Affine3DTransform.cpp.
