Detailed Description
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:
- Profile position in object space (two XYZ points).
See method getProfileObjectPos().
- Profile location in the data volume (two IJK indices).
See method getProfileDataPos().
- Number of values along the profile.
See method getProfileDataPos().
- For each value along the profile: the voxel value and its corresponding IJK location.
See method getProfileValue().
Notes:
- To get information about all voxels intersected by the ray, the application must set the pickAll flag of the SoRayPickAction to TRUE. (This is different than the behavior of SoVolumeRenderDetail.
Limitations:
- If multiple volumes are being combined under an SoMultiDataSeparator, the detail class only returns values for the first volume in the scene graph.
