c# - How alter the camera in opengl so I can see my entire surface plot on screen? -

i using sharpgl in wpf application , have surface plot. problem when try move lookat camera away lot of plot disappears.... i'm new opengl, how can adjust camera can see plot multiple sides?

not sure using sharpgl, in perspective state want far clipping plane @ 100 , you're setting camera @ -105, 105, -105, further away 100. might fix problem setting far clipping plane further away?
