Rendering methods available for use by the surface mesh primitive. Different methods may have different performance characteristics and require different video card support. When in doubt, use Automatic.

Member	Value	Description
eStkGraphicsSurfaceMeshRenderingMethodGeometryShader	0	Render the surface mesh using a geometry shader. Requires OpenGL 3.0 or 2.0 with the ARB_geometry_shader4 extension.
eStkGraphicsSurfaceMeshRenderingMethodVertexShader	1	Render the surface mesh using a vertex shader. Requires OpenGL 2.0 or 1.5 with the following extensions: GL_ARB_vertex_shader GL_ARB_fragment_shader GL_EXT_stencil_two_side
eStkGraphicsSurfaceMeshRenderingMethodAutomatic	2	Render the surface mesh using an automatically selected method based on the capabilities of the video card.
