OdDgView Class

Syntax

C++

class OdDgView : public OdDgElement, public OdDgViewAsPerspectiveCamera, public OdDgViewAsOrthography;

Description

There are 2 alternatives: parallel views and perspective views (virtual camera).
The methods related to camera are available only when camera is on (getUseCameraFlag() == true).
This class does not care about translation between parameters if the modes are switched.

Corresponding C++ library: TG_Db
