148	ToDo:
149
150	The intersection works and the selector highlighter is set and displayed correctly.
151	Next steps:
152	* Hide the highlighter and disable the intersection/drag tracking on diabled edit mode.
153	* catch up dragging values and translate them in the correct coordinate frame.
154	* apply dragging values:
155	* a) either on the texture coordinate while the grid is constant,
156	* b) or apply them on the grid node coordinates while the texture coordinates are constant (check/compare solutions!)
157	*
158
159
160	*
161	* Layout vom Distortion System
162	*
163	* Das distortion System unterstützt Verzerrungen, die pro Kanal jeweils nur eine camera verwenden.
164	* Verzerrungen, die das Bild je Kanal aus mehreren Cams zusammensetzen um Views>=180° zu erreichen werden nicht unterstützt da hierfür ein Camera Setup nötig wäre, welches nicht im distortion-Container gespeichert wird (Sonderfall, zu speziell für das Dist-Framework)
165	*
166	*
167	* modul Funktionen / Description
168	*
169	* [] plugin .dist [done] load / Save distContainers loads and saves via serializers the distortion container from/to file.
170	* Ensures the Coordinates are normalized before saving the container.
171	* Load:
172	* [done] * use ReaderWriterOSG2 to load container
173	* * invoke osgViewer::setUpViewForManualDistortion(distSet, screenNum, projectorMatrix) to set up distortion
174	* Save:
175	* * check if container is normalized. if not, copy and normalize container
176	* [done] * use ReaderWriterOSG2 to save container
177	*
178	*
179	* [done] Distortion Container Der Container wird immer normalisiert gespeichert, alle Koordinaten (Mesh+TexCoords) werden im Range [0-1]angespeichert.
180	* Er beinhaltet die folgenden Distortion Details:
181	* - Blendmap (osgImage)
182	* - Mesh Dimensions (rows, columns)
183	* - Mesh Type (GLenum QUAD_STRIP, ...)
184	* - Mesh Coordinates [0-1]
185	* - Texture Coordinates [0-1]
186	* - textureUnit for Scene RTT (z.B.: 0)
187	* - textureUnit for blendmap (z.B.: 1)
188	* - screenNum
189	* - slaveCam projectionOffset (wird mit der vom master multipliziert und auf die slave cam angewendet, meist Identity)
190	* - slaveCam viewOffset (wird mit der vom master multipliziert und auf die slave cam angewendet, verwendet für translation und rotation offset)
191	*
192	* [] Todo: get set methode für das Mesh implementieren.
193	*
194	* Besitz: Da osgViewer distSets ohne Manipulationsmöglichkeit konsumieren können soll, muss der Container vom Viewer verwaltet werden. der manipulator greift darauf zu, das plugin kann container entgegen nehmen oder zurückgeben, hat aber keinen direkten kontakt zur container instanz von osgViewer
195	*
196	* osgViewer im construtor (anfangs ersatzweise in der main.cpp) : -dist <distFile> => load and apply distortion [via setUpViewForManualDistortion(std::string distFile)]
197	* setUpIntensityMapBlending(string filepath, int rrtTexUnit=1, int scenTexUnit=0): Simple function providing a file path, and optionally the texUnits to use.
198	* Will invoke the more detailed funtion (below) for setup.
199	* setUpIntensityMapBlending(osg::StateSet* stateset, osg::Image* intensityMap, unsigned int screenNum, int rttSceneTextureUnit, int intensityMapTextureUnit)
200	* setUpViewForManualDistortion(osgViewer::DistortionSet* distSet, unsigned int screenNum, const osg::Matrixd& projectorMatrix)
201	* setUpViewForManualDistortion(std::string distFile, unsigned int screenNum, const osg::Matrixd& projectorMatrix) is invoked by -dist <distFile>, reads distSet via osgDB::readObjectFile(), calls setUpViewForManualDistortion(osgViewer::DistortionSet* distSet, unsigned int screenNum, const osg::Matrixd& projectorMatrix) to setup the distortion.
202	*
203	* distortionManipulator abgeleitet von osgGA::GUIEventHandler
204	* Grundfunktionen:
205	* [done] - Key to Show Distortion Mesh / Intensity Map / none
206	* [done] - Key to Save distortion Container - via osgDB::writeObjectFile(const osg::Object& object, const std::string& filename, const Options* options). osgDB & registry determines and loads the approriate plugin bythe file ending (.dist).
207	* [.] - Key to toggle MANUAL mode between blending und distortion setup
208	* [done] - Key to toggle distortion setup:
209	* DISABLED distortion/blending modifications are forbidden (ggfs. beim Verlassen von DISABLED ggf. auf singleThreaded wechseln und beim aktivieren von DISABLED wieder auf das alte threadingmodel. Alternativ die data variance des meshes/Blendmap beeinflussen)
210	* MANUAL distortion/blending modification via mouse Selection and drag'n'drop
211	* DELEGATED distortion/blending modification by calling a foreign class or calling a subclassed function
212	* [done] - Key to control if mouse drags affects mesh coordinates or rttScene texture coordinates. Default: Mesh coordinates.
213	* - Key to reset Distortion.
214	* [done] - Key to reset Blending.
215	* [done] - Key to Show/Hide distortion HUD
216	*
217	* Die Funktion handle( const osgGA::GUIEventAdapter& ea, osgGA::GUIActionAdapter& aa ):
218	* [done] DISABLED: ignorieren
219	* [.] MANUAL : auf mouse selection und drags horchen und auf Distortion Anwenden. bei keys die obigen funktionen realisieren
220	* [.] DELEGATED : beim typ FRAME die Distortion zur Veränderung stellen indem der Pointer an die bearbeitende Funktion übergeben wird:
221	* subsclassed function aufrufen bzw foreignClass->delegateDistortionSetup(distContainer& container)
222	*
223	* [done] Vertex Highlighter für die manuelle Verzerrung soll nur eingeblendet werden wenn der Betriebsmodus MANUAL ist.
224	*
225	*
226	* direct to do:
227	*
228	* Plugin fertigstellen
229	* extViewer::setUpViewForManualDistortion(std::string distFile)
230	* Load Funktion vom osgViewer (ersatzweise Anfangs in der main.cpp) fertigstellen : -dist <distFile> weiterreichen and extViewer::setUpViewForManualDistortion(std::string distFile)
231	* Laden des Containers.
232	* reset distortion implementieren.
233	* Anwenden der distortion auf die Meshknoten oder die texturekoordinaten
234	*
