Class TeamActionInterpreter

Version:

1.0 Last Modification 20 September 2000 The TeamActionInterpreter.java file contains the logic that supports and interprets user input from the TeamPanel.java. This file also supports the aggregation and disaggregation of an independent human entity to a group, and allows the user the ability to order coordinated, tactical actions among human and non-human entities.

Entity coordinate systems (right-hand rule applies):

          DIS                 VRML

      -Z entity up         Y entity up
           ^                   ^
           |                   |
           |                   |
           |                   |
           +------> X          +-------> X    nose of entity body ( North )
          /                   /
         /                   /
        /                   /
       Y                   Z
         right-hand side
         of entity body ( East )

  Rotation angle axes (right-hand rule applies):

           DIS        VRML      Angle of rotation

  Roll      X          X         phi
  Pitch     Y          Z        theta
  Yaw       Z         -Y         psi
