AsdGrapg3D, an OpenGL-based Excel Addin

AsdGraph3D is an OpenGL-based Excel Addin that plots 3D surfaces directly from user-specified cell ranges within MS Excel worksheets (from one or several open workbooks). The tight integration with MS Excel is what differentiates AsdGraph3D from rest of the 3D surface plotters.
