|RhinoViewportChangeToPerspectiveProjection Method (Boolean, Double)|
Use this function to change projections of valid viewports from parallel to perspective.
It will make common additional adjustments to the frustum and camera location so the
resulting views are similar. The camera direction and target point are not be changed.

Public Function ChangeToPerspectiveProjection (
symmetricFrustum As Boolean,
lensLength As Double
) As Boolean
- Type: SystemBoolean
true if you want the resulting frustum to be symmetric.
- Type: SystemDouble
(pass 50.0 when in doubt) 35 mm lens length to use when changing from parallel to perspective
projections. If the current projection is perspective or lens_length is <= 0.0, then
this parameter is ignored.
If the current projection is perspective and bSymmetricFrustum, FrustumIsLeftRightSymmetric()
and FrustumIsTopBottomSymmetric() are all equal, then no changes are made and true is returned.
