ViewportInfoChangeToSymmetricFrustum Method
If needed, adjusts the current frustum so it has the specified symmetries and adjust the camera location so the target plane remains visible.

Namespace: Rhino.DocObjects
Assembly: RhinoCommon (in RhinoCommon.dll) Version: 5.1.50000.0 (5.0.20693.0)
Syntax
public bool ChangeToSymmetricFrustum(
	bool isLeftRightSymmetric,
	bool isTopBottomSymmetric,
	double targetDistance
)

Parameters

isLeftRightSymmetric
Type: SystemBoolean
If true, the frustum will be adjusted so left = -right.
isTopBottomSymmetric
Type: SystemBoolean
If true, the frustum will be adjusted so top = -bottom.
targetDistance
Type: SystemDouble
If projection is not perspective or target_distance is RhinoMath.UnsetValue, then this parameter is ignored. If the projection is perspective and targetDistance is not RhinoMath.UnsetValue, then it must be > 0.0 and it is used to determine which plane in the old frustum will appear unchanged in the new frustum.

Return Value

Type: Boolean
Returns true if the viewport has now a frustum with the specified symmetries.
