'Declaration
 
Public Overloads Sub MemoryEfficientSetFrame( _
   ByVal image As RasterImage, _
   ByVal frameIndex As Integer, _
   ByVal imagePosition As Point3D, _
   ByVal remove As Boolean _

'Usage
 
Dim instance As Medical3DObject

public:
void MemoryEfficientSetFrame( 
   RasterImage^ image,
   int frameIndex,
   Point3D imagePosition,
   bool remove
)

Parameters

image: Leadtools.RasterImageused to fill a portion of the object.
frameIndex: The index that represents the place of the image to set in the 3D object.
imagePosition: the position of the frame being set. Get this value from the DICOM file.
remove: true to dispose of the image after copying its data and placing it into the 3D object; false, otherwise.

You must add the Medical3DObject to the Medical3DContainer before using this method. Refer to Medical3DContainer.Objects collection.
You must first initialize the memory efficient feature before using this method. To initialize the feature, use the MemoryEfficientInit method.
You need to call this method multiple times, each with different frameIndex, in order to fill the 3D object. The number of times is based on the depth

depth

The depth of the 3D object, or the number of frames used to create the 3D object.

parameter used when calling MemoryEfficientInit.
You do not need to set frames in order. However, you need to fill the whole object by covering all the indexes from 0 to depth - 1. The area that was not filled will be black when rendering the object.
This overloaded method is used when you want to sort the series frames based on their ImagePositionPatient Dicom tag.
