General definitions

  • Reference Direction and Distances

    The algorithm calculates the distance in a Reference Direction between the core gravity center of a sample in a domain and the contact with a second domain. This distance is:

    • positive if the sample lies before the contact in the Reference Direction,
    • negative if the sample lies after the contact in the Reference Direction.

    The contact End2/Begin3 is at a distance of 1.5 m from the Gravity Center n°1 along the Reference Direction whereas the same contact End2/Begin3 is at a distance of -2 m from the Gravity center n°4

  • Oriented Contact

    Statistics are calculated in the chosen Reference Direction and in the opposite direction. The way of scanning the drillholes is important. The following figures show two configurations with different Reference Directions.

    Considering the contact from Domain 1 to Domain 2:

    • a direct contact is a transition from Domain 1 to Domain 2
    • an indirect contact is an inverse transition (i.e. from Domain 2 to Domain 1)
