IViewPoint Interface
IViewPoint Interface
- Store
- SetCurrent
- GetViewVolumeDimensions
- SetViewVolumeDimensions
- SetCurrent2
IViewPoint interface provides programmatic access to a
viewpoint..
IViewPoint can be obtained from the
IViewPointArray interface with a call to GetAt method.
Query path: KernelCAD > GetView
> IViewPointArray >
GetAt > IViewPoint.
Alternative Path:
KernelCAD > GetView
> IPropertyArray
>
IPropertyArray.GetProperty("ViewPoints") > IArray2
> GetAt > IViewPoint.

HRESULT Store( )
Remarks:
The method stores configuration of view currently displayed in 3D window in
members of this viewpoint.
HRESULT SetCurrent( )
Remarks:
The method restores configuration of view which was
current at the moment when the Store() method was called or set programmatically
in properties of the viewpoint. The method does not repaint the view
automatically. Call UpdateView
to redraw the window.
HRESULT GetViewVolumeDimensions(double* sx, double* sy, double* sz)
Parameters
sx,sy,sz- [out] - The current dimension
of the Viewing Volume
Remarks:
The method returns dimensions of the Viewing Volume stored in this viewpoint. Z dimension is a read-only property.
HRESULT SetViewVolumeDimensions(double sx, double sy)
Remarks:
The method modifies dimension of the Viewing Volume stored in this
viewpoint. Z dimension is a read-only property. It is updated by software
automatically.
HRESULT SetCurrent2(int transitionMilliseconds)
Parameters
transitionMilliseconds- [in] - Length of
the animation in milliseconds (1/1000 of a second)
Remarks:
Similarly to SetCurrent the method activates the
configuration of view stored in this view point. The difference is that the
transition is performed in smooth animated way. The parameter specifies duration
of the transition from the configuration currently displayed by the view to
configuration stored in this view point
