public enum Medical3DProjectionMethod
Value | Member | Description |
---|---|---|
0 | Orthogonal | The camera will use the Orthogonal projection method. |
1 | Perspective | The camera will use the Perspective projection method (Default). |
Orthogonal makes the camera neglect the distance factor when viewing the object. If the object is viewed from two different distances, it will NOT become smaller or bigger. The perspective view however, resembles the real-life view by making the object look smaller if it is far away, or bigger if it is closer.
