public SoSFEnum<SoVolumeShapeCompositions> composition { get; }

Property Value

Type: SoSFEnumSoVolumeShapeCompositions
Remarks

. Default is ALPHA_BLENDING.

ALPHA_BLENDING blends the R, G, and B components for each pixel based on the their alpha values.

SUM_INTENSITY draws the sum of the R, G, and B components for each pixel.

MAX_INTENSITY draws the maximum R, G, and B components for each pixel.

MIN_INTENSITY draws the minimum R, G, and B components for each pixel.

Note: In all modes, blending is done against the background color of the scene (or the object behind the volume). This means that, using MIN_INTENSITY for example, if the background color is black then 0,0,0 is already the minimum RGB value and the volume will not be visible. Generally when using MIN_INTENSITY the background color should be set to white (1,1,1) and when using MAX_INTENSITY or SUM_INTENSITY the background color should be set to black (0,0,0). To set the background color see the setBackgroundColor method of the appropriate RenderArea class, for example OIV.Inventor.Win.SoWinRenderArea on Windows.
