SoCameraInteractor.ZoomInWindow Method

SoCameraInteractorZoomInWindow Method

Zooms to the region defined by the given corners in normalized screen coordinates.

Namespace: OIV.Inventor.ViewerComponents
Assembly: OIV.Inventor (in OIV.Inventor.dll) Version: 2024.1.1.0 (2024.1.1)

Syntax

public void ZoomInWindow(
	SbVec2f topLeftCorner,
	SbVec2f bottomRightCorner,
	SbViewportRegion vpRegion
)

Public Sub ZoomInWindow ( 
	topLeftCorner As SbVec2f,
	bottomRightCorner As SbVec2f,
	vpRegion As SbViewportRegion
)

public:
void ZoomInWindow(
	SbVec2f topLeftCorner, 
	SbVec2f bottomRightCorner, 
	SbViewportRegion vpRegion
)

member ZoomInWindow : 
        topLeftCorner : SbVec2f * 
        bottomRightCorner : SbVec2f * 
        vpRegion : SbViewportRegion -> unit

topLeftCorner: Type: OIV.InventorSbVec2f
top left corner in normalized screen coordinates (0 <= x,y <= 1)
bottomRightCorner: Type: OIV.InventorSbVec2f
bottom right corner in normalized screen coordinates (0 <= x,y <= 1)
vpRegion: Type: OIV.InventorSbViewportRegion
the actual viewport region

Remarks

Perspective camera: This method modifies the heightAngle field. Modifying the heightAngle field changes the projection, similar to changing the focal length of a camera. Making the heightAngle very small or very large may cause rendering artifacts. Therefore the OIV.Inventor.ViewerComponents.SoCameraInteractor.DollyInWindow(OIV.Inventor.SbVec2f, OIV.Inventor.SbVec2f, OIV.Inventor.SbViewportRegion) method is recommended when using a perspective camera.
Orthographic camera: This method modifies the height field.
