ProjectionMethod Property

Summary

Gets or sets the camera's projection method.

Syntax

C++

public Medical3DProjectionMethod ProjectionMethod { get; set; }

  
Public Property ProjectionMethod As Leadtools.Medical3d.Medical3DProjectionMethod

public: 
property Leadtools.Medical3d.Medical3DProjectionMethod ProjectionMethod { 
   Leadtools.Medical3d.Medical3DProjectionMethod get(); 
   void set (    Leadtools.Medical3d.Medical3DProjectionMethod ); 
}

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.
