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 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.
