)

Constructs a projector framework from the following parameters.

  • Pers is true if the view is a perspective view and false if it is an axonometric one;
  • Focus is the focal length if a perspective view is defined;
  • DX, DY and DZ are the coordinates of the projection vector;
  • XAt, YAt and ZAt are the coordinates of the view point;
  • XUp, YUp and ZUp are the coordinates of the vertical direction vector.
