View Class
This class is the abstract base class for classes that implement Viewport objects in GUI display windows. Each Viewport object consists of a collection of objects to be viewed and camera parameters that define the view. For more information, see Working with Views.

  Name Description
Public property AutoDelete Property that indicates whether the object should be automatically deleted by the Garbage Collector.
(Inherited from DisposableWrapper)
Public property BackClip Property that represents back clip distance from the target of this Viewport object.
Public property Background Property that represents background object for this view.

Public property Device Property that represents GS Device object associated with this view.
Public property EnableBackClip Property that indicates whether back clipping is enabled for this Viewport object.
Public property EnableFrontClip Property that indicates whether front clipping is enabled for this Viewport object.
Public property EnableStereo Property that indicates whether stereo viewing is enabled for this Viewport object.
Public property ExceededBounds Property that indicates whether any view parameters have exceeded their boundaries. The following calls are monitored: * dolly() * orbit() * pan() * roll() * setBackClip() * setFrontClip() * setView() * zoom()
Public property FieldHeight Property that represents WCS projection plane (field) height for this Viewport object.

(Inherited from DisposableWrapper)
Public property IsPerspective Property that indicates whether the projection type for the viewport object is perspective or parallel.
Public property IsValid Property that indicates whether this Viewport shows the correct image. If this property is true, the following conditions are met: * No part of GUI area is flagged for refresh. * All rasterizations are complete. * The rendering pipeline has been flushed.
Public property IsVisible Property that indicates whether the view is not hidden.

Public property Mode Property that represents rendering mode for this view. This property can be one of the following: Name Value Description BoundingBox -1 Bounding box. For internal use only. Optimized2D 0 Standard *display*. Optimized for 2D. Wireframe 1 Standard *display*. Uses 3D pipeline. HiddenLine 2 Wireframe *display*. Hidden lines removed. FlatShaded 3 Faceted *display*. One *color* per face. GouraudShaded 4 Smooth shaded *display*. Colors interpolated between *vertices*. FlatShadedWithWireframe 5 Faceted *display* with wireframe overlay.

Public property ObjectToDeviceMatrix Property that represents the matrix that transforms coordinates from model space to screen space for this Viewport object.
Public property Position Property that represents WCS camera position for this Viewport object.

Public property ScreenMatrix Property that represents the matrix that transforms normalized device space to screen space for this Viewport object.
Public property StereoParameters Property that represents stereo viewing parameters for this Viewport Object. The StereoParameters encapsulate magnitude of view separation and parallax value. Magnitude controls view eye separation, and hence the stereo effect. * A magnitude of 1.0 is the default value. * A magnitude of 0.0 produces no stereo effect. * A magnitude of 2.0 produces a double stereo effect. Parallax adjusts the zero parallax plane. * A parallax of 1.0 is the default value. An object centered at the target will be half-in and half-out of the screen. * A parallax of 0.0 moves the object into the screen. * A parallax of 2.0 move the object out of the screen.
Public property Target Property that represents WCS camera target for this Viewport object.
Public property UnmanagedObject Property that represents a pointer to an unmanaged object.
(Inherited from DisposableWrapper)
Public property UpVector Property that represents WCS camera up vector for this Viewport object.
Public property UserGiContext Property that represents GiContext object associated with this Viewport object.
Public property ViewingMatrix Property that represents the matrix that transforms world space to view space for this Viewport object.
Public property Viewport Property that represents the size and position of this Viewport object. The extents are based on 2 points: * lower-left corner in nomalized device coordinates [0.0 .. 1.0] * upper-right corner in nomalized device coordinates [0.0 .. 1.0]
Public property ViewportBorderProperties Property that represents the color and width of the border for this Viewport object.
Public property ViewportBorderVisibility Property that indicates whether viewport border is visible.
Public property ViewportClipRegion Property that represents polygonal clip region for this Viewport object.
Public property VisualStyle Property that represents a visual style that is used.
Public property VisualStyleId Property that represents ID of visual style that is used.
Public property WorldToDeviceMatrix Property that represents a matrix that transforms coordinates from world space to screen space for this Viewport object.
