Opacity Property

Gets or sets the opacity value (transparency) of the 3D object.

Syntax

C#
Visual Basic
Objective-C
Java
C++

public float Opacity {get; set;}

'Declaration
 
Public Property Opacity As Single

'Usage
 
Dim instance As Medical3DObject
Dim value As Single
 
instance.Opacity = value
 
value = instance.Opacity

public:
property float Opacity {
   float get();
   void set (    float value);
}

Property Value

The opacity value (transparency) of the 3D object.

Remarks

This feature works only with objects rendered using the VRT rendering technique.

To switch to the VRT rendering technique, set the value of the VolumeType property to Medical3DVolumeType.VRT.

Opacity values affect the amount of voxel transparency. Voxels still participate in the final 3D result and aren't totally removed as in the remove density method.
