SoVolumeRenderingQualitycolorInterpolation Property |
Controls interpolation of data values used for color lookup.
Namespace: OIV.VolumeViz.Nodes
If false, interpolation is not done on data values used to access the colormap but is still done when computing gradient for lighting. This may be used to render a segmented dataset where interpolation is not appropriate. Default is true. Only affects gradient based lighting (OIV.VolumeViz.Nodes.SoVolumeRenderingQuality.m_lighting field).
Generally it's better to set the OIV.VolumeViz.Nodes.SoVolumeShape.m_interpolation field to NEAREST, unless you really want to use gradient based lighting.
