RemarksA successful pick operation returns an OIV.Inventor.SoPickedPoint object. If the picked geometry is an OIV.VolumeViz.Nodes.SoVolumeRender node, use the getDetail method and cast the result to this class to get extra information about the the pick.
OIV.VolumeViz.Details.SoVolumeRenderDetail returns information about the first (closest) non-transparent voxel along the pick ray and/or information about all the voxels intersected by the pick ray (called a profile). For the first non-transparent voxel (if any) on the pick ray, it returns XYZ position, IJK location, and data value. For the profile defined by all the intersected voxels, it returns:
Profile position in object space (two XYZ points)
Profile location in the data volume (two IJK indices)
Number of values along the profile
Each voxel value and corresponding IJK location
Use the methods in OIV.VolumeViz.Details.SoVolumeDetail to get information about the data values of the picked voxels. Use the getRgba... methods in this class to get information about the mapped RGBA colors of the picked voxels. Because these methods return colors, they always return information based on the (possibly subsampled) tiles currently in memory.
GPU picking: Please see the discussion of GPU picking in OIV.VolumeViz.Details.SoVolumeDetail.
Limitations:
If multiple volumes are being combined under an OIV.LDM.Nodes.SoMultiDataSeparator, the detail class only returns values for the first volume in the scene graph.
