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.
