Stores detail information about a picked voxel or pick ray in a data volume.
A successful pick operation returns an SoPickedPoint object. If the picked geometry is an SoFenceSlice node, use the getDetail method and cast the result to this class to get extra information about the pick.
SoFenceSliceDetail 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 the XYZ position in 3D space, IJK location in voxels and the data value. See method getFirstNonTransparentValue().
For the profile defined by all the intersected voxels, it returns:
