<p>Description: Expert user function to get a pointer to control vertex memory. If you are not an expert user, please use ON_BezierSurface::GetCV( ON_3dPoint&amp; ) or ON_BezierSurface::GetCV( ON_4dPoint&amp; ). Parameters: cv_index0 - [in] (0 &lt;= cv_index0 &lt; m_order[0]) cv_index1 - [in] (0 &lt;= cv_index1 &lt; m_order[1]) Returns: Pointer to control vertex. Remarks: If the Bezier surface is rational, the format of the returned array is a homogeneos rational point with length m_dim+1. If the Bezier surface is not rational, the format of the returned array is a nonrational euclidean point with length m_dim.

<p>NOTE: These members are left "public" so that expert users may efficiently create bezier curves using the default constructor and borrow the knot and CV arrays from their native NURBS representation. No technical support will be provided for users who access these members directly. If you can't get your stuff to work, then use the constructor with the arguments and the SetKnot() and <a class="el" href="../../d7/dc7/class_o_n___bezier_surface.html#a4982ff92c237fc732b956329ac9e7c21">SetCV()</a> functions to fill in the arrays. &gt;= 1 </p>
