Creates a new parallel projection to the provided coordinate system

Creates a clone of the provided projection

Creates a new standard projection according to Projection..::..StandardProjection

Constructor required by deserialization

Creates a new parallel projection with the provided direction and the direction of the vector that should become the vertical direction.

Returns a BoundingRect in the 2d world coordinate system according to the provided view positions. The view coordinate system is the windows forms system. The 2d world coordinate system is for the parallel projection a plane perpendicular to the projection direction scaled the same way as the model. For the perspective projection it is the back plane of the displayed frustum of pyramid.

Returns a clone of this projection

Returns the point in the worldcoordinate system corresponding to the (mouse-) position p and the drawingplane

Liefert den Raumpunkt (Welt3D) zum Welt2D Punkt gemäß Zeichenebene (DrawingPlane)

Implements GetObjectData(SerializationInfo, StreamingContext)

Returns a PickArea, viewRect is in window coordinates

Returns a PickArea, viewRect is in window coordinates

Returns a PickArea, rectWorld2D is in 2-d world coordinates

Liefert die Werte für die Platzierung. Achtung: die Y-Werte müssen mit dem negativen Faktor multipliziert werden, denn die Platzierung dreht die y-achse um!

Gets the position of a given point (usually a mouse position in view coordinates) in a given plane.

Returns a beam corresponding to the 2-dimensional mouse position. The mouse position corresponds to a beam in the model which is seen as a point from the viewpoint. The result is in world coordinates of the model. Works for both parallel and perspective projection.

Berechnet die Projektion des gegebenen Punktes ins Zweidimensionale mit Berücksichtigung der Skalierung und Platzierung im Zweidimensionalen, also in das zweidimensionale Papierkoordinatensystem und nicht in das Weltkoordinatensystem.

Berechnet die Projektion des gegebenen Punktes ins Zweidimensionale ohne Berücksichtigung der Skalierung und Platzierung im Zweidimensionalen, also in das zweidimensionale Weltkoordinatensystem und nicht in das Papierkoordinatensystem.

Sets the view direction and the vertical direction of this projection.

Stellt die Platzierung im Zweidimensionalen ein: Das Quellrechteck soll in das Zielrechteck passen.

Returns the provided point in the world coordinate system

Returns the window position of a point in the world coordiate system. Point (0,0) is the top left point of the window

Some Attributes refer to paper bound dimensions: e.g. the linewidth or textsize may be specified in mm on the paper. So we need the posibility to transform linear dimensions from layout to world. This is doune by the LayoutFactor;

A factor for the display line width

Flag indicating the use of line width

Returns true if this projection is a perspective projection in contrast to a parallel projection

Display hint, whether to show the drawing plane

Event beeing issued when the projection changes
