RhinoViewportChangeToParallelProjection Method

Use this function to change projections of valid viewports from perspective to parallel. It will make common additional adjustments to the frustum so the resulting views are similar. The camera location and direction will not be changed.

Namespace:  Rhino.Display
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
Syntax
Copy
public bool ChangeToParallelProjection(
	bool symmetricFrustum
)

Parameters

symmetricFrustum
Type: SystemBoolean
true if you want the resulting frustum to be symmetric.

Return Value

Type: Boolean
If the current projection is parallel and bSymmetricFrustum, FrustumIsLeftRightSymmetric() and FrustumIsTopBottomSymmetric() are all equal, then no changes are made and true is returned.
