Implementing a new coordinating system via parenting. The idea is, that every object, every point in the world has a relative and an absoulte coordinate.

  • relative coordinate: is defined relative to a parent
  • absolute coordinate: is defined in absolute openGL coordinate space

The relative coordinates make up a tree, from a base parent NullParent all the other parents are derived from.
The source code will be writen into the files p_node.h and, the classes will be called PNode
There will be some HelperParent that will be used to make parents that have no direct use in the world.

Not yet finished.

what we need is:

  • Rotation: aroud the parent if the parent rotates
  • Simplicity: everything has to work out of the Box. The derived classes of p_node do only have to be parented, the rest is done by p_node
  • One Sided:
    • either setParent or setChild
    • children/parents must be private (or at least protected) or errors occure
  • have to talk about this matter @patrick & @bensch
