Medical3DObject Class

The Medical3DObject class is used to contain the 3D object source image. It also contains properties and methods for adjusting object characteristics.

Object Model

Syntax

Visual Basic
C#
WinRT C#
WinRT JavaScript
C++/CLI

public class Medical3DObject

'Declaration
 
Public Class Medical3DObject

'Usage
 
Dim instance As Medical3DObject

public sealed class Medical3DObject

function Leadtools.Medical3D.Medical3DObject()

public ref class Medical3DObject

Remarks

This is the class that contains the 3D object. You should populate this class with a multi-page image. Then, you can add the object to the container. It is best to use memory efficient loading when creating large 3D objects. For more information, refer to the MemoryEfficientInit method.
