SetViewport

#Since v6.0
public void SetViewport(RhinoViewport viewport)
Set the viewport for the hidden line drawing (HLD). The viewport supplies the projection that determines the visibility of curves, and the HLD coordinate system in which the resulting curves are represented. The HLD-coordinate system is a right handed system for 3-D model space, in which the 3rd coordinate direction is the projection direction. In particular the z-coordinate direction points from the scene toward the camera.
Parameters:
viewport (RhinoViewport)A copy of rhinoViewport is made inside of HiddenLineDrawing.
Returns: True if the viewport has been set.

SetViewport

#Since v6.0
public void SetViewport(ViewportInfo viewport)
Set the viewport for the hidden line drawing (HLD). The viewport supplies the projection that determines the visibility of curves, and the HLD coordinate system in which the resulting curves are represented. The HLD-coordinate system is a right handed system for 3-D model space, in which the 3rd coordinate direction is the projection direction. In particular the z-coordinate direction points from the scene toward the camera.
Parameters:
viewport (ViewportInfo)A copy of viewportInfo is made inside of HiddenLineDrawing.
Returns: True if the viewport has been set.
