ProjectionMethod Property

Gets or sets the camera's projection method.

Syntax

C#
Visual Basic
Objective-C
Java
C++

public Medical3DProjectionMethod ProjectionMethod {get; set;}

'Declaration
 
Public Property ProjectionMethod As Medical3DProjectionMethod

'Usage
 
Dim instance As Medical3DCamera
Dim value As Medical3DProjectionMethod
 
instance.ProjectionMethod = value
 
value = instance.ProjectionMethod

public:
property Medical3DProjectionMethod ProjectionMethod {
   Medical3DProjectionMethod get();
   void set (    Medical3DProjectionMethod value);
}

Property Value

A Medical3DProjectionMethod value that represents the projection method used for the camera.

Remarks

You can set the value of this property to either Orthogonal or Perspective. The default value is Perspective. Using the Orthogonal value makes the camera neglect the distance factor when viewing the object. This means that if the object is viewed from two different distances it will NOT become smaller or bigger. The Perspective view resembles a real-life view by making the object appear smaller if it is further away and larger if it is closer.
