In This Topic

Controls the gamma applied to transfer function lookups during volume rendering.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Property GammaTransfer As Single

'Usage
 
Dim instance As DicomImage3D
Dim value As Single
 
instance.GammaTransfer = value
 
value = instance.GammaTransfer

public float GammaTransfer {get; set;}

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

Remarks

Lighting calculations are performed in gamma 2.2 space to maintain physical accuracy and compatibility with parameter values (such as diffuse and specular contributions) used by other renderers. However, this can cause the transfer function output to appear washed out because gamma conversion may effectively be applied twice to the texture. To compensate for this, a separate gamma control is provided for transfer textures. By default, a value of 0.45 is used, which approximately counteracts the gamma conversion that is applied later during the final image processing.
