A framework to define selection of a sensitive group by a sensitive entity which is a set of 3D sensitive entities. Remark: 2 modes are possible for rectangle selection the group is considered selected 1) when all the entities inside are selected in the rectangle 2) only one entity inside is selected by the rectangle By default the "Match All entities" mode is set.
