The matrix generated can be concatenated with the view matrix, for example, to create the view as seen by a planar mirror.</P> 43 44<H2>See Also</H2> 45<P class="reference"> 46<A href="../structures/Mtx_MtxPtr.html">Mtx, MtxPtr</A>, 47<A href="../structures/Point3d_Point3dPtr.html">Point3d, Point3dPtr</A>, 48<A href="../structures/Vec_VecPtr.html">Vec, VecPtr</A>, 49<A href="../general/MTXMultVecSR.html">MTXMultVecSR</A>, 50<A href="../general/MTXMultVecArray.html">MTXMultVecArray</A>, 51<A href="../general/MTXMultVecArraySR.html">MTXMultVecArraySR</A> 52</P> 53 54<H2>Revision History</H2> 55<P> 562006/03/01 Initial version.<br> 57</p> 58 59<hr><p>CONFIDENTIAL</p></body> 60</HTML>
