-===== Gamut =====
+===== Gamut Mapping =====
+Gamut is a colored texture to define how 3D values will be colored.
+Since 0.8.3.2265 this feature is available.
+Here an example of a simple gradient gamut texture:
+{{:0.8.3:gamut.jpg?nolink|}}
+TGorillaVolumetricMesh allows to configure the coloring method by some properties:
+^Property^Description^
+|Gamut|Texture used for mapping the 3D value during Raytracing|
+|GamutMode|Defines when and how the value-color mapping happens. Here different modes are available: GamutNone, GamutByValue, GamutByValueMultiply, GamutBySum, GamutBySumMultiply|
+|GamutFactor|A factor applied to the absolute 3D value before mapping onto the gamut texture (default value is 1.0)|
+=== Modes ===
+The available gamut modes allow to control the output of color mapping.
+^Mode^Description^
+|GamutNone|Gamut mapping is disabled|
+|GamutByValue|Gamut mapping will be applied to each 3D value on the casted ray.|
+|GamutByValueMultiply|Gamut mapping will be applied to each 3D value on the casted ray and afterwards multiplied with the previously computed color value.|
+|GamutBySum|Gamut mapping will be applied to the final casted ray value.|
+|GamutBySumMultiply|Gamut mapping will be applied to the final casted ray value and afterwards multiplied with the previously computed color value.|
