123 | ToDo: |
---|
124 | |
---|
125 | The intersection works and the selector highlighter is set and displayed correctly. |
---|
126 | Next steps: |
---|
127 | * Hide the highlighter and disable the intersection/drag tracking on diabled edit mode. |
---|
128 | * catch up dragging values and translate them in the correct coordinate frame. |
---|
129 | * apply dragging values: |
---|
130 | * a) either on the texture coordinate while the grid is constant, |
---|
131 | * b) or apply them on the grid node coordinates while the texture coordinates are constant (check/compare solutions!) |
---|
132 | * |
---|
133 | |
---|
134 | |
---|
135 | * |
---|
136 | * Layout vom Distortion System |
---|
137 | * |
---|
138 | * Das distortion systme unterstüzt verzerrungen ,die pro kanal auhc nur eine camera verwenden. |
---|
139 | * Verzerrungen, die das Bild je Kanal aus mehreren Cams zusammensetzen um Views>=180° zu erreichen werden nicht unterstützt da hierfür das Camera Setup nötig wäre, welches nicht im distortion-Container gespeichert wird (Sonderfall, zu speziell für das Dist-Framework) |
---|
140 | * |
---|
141 | * |
---|
142 | * modul Funktionen / Description |
---|
143 | * |
---|
144 | * [postponed] plugin .dist load / Save distContainers loads and saves via serializers the distortion container from/to file. Can potentially be replaced by a simple extension alias to osgt|b|x |
---|
145 | * |
---|
146 | * |
---|
147 | * [done] Distortion Container Beinhaltet die folgenden Distortion Details: |
---|
148 | * - Blendmap (osgImage) |
---|
149 | * - Mesh Dimensions (rows, columns) |
---|
150 | * - Mesh Type (GLenum QUAD_STRIP, ...) |
---|
151 | * - textureUnit for Scene RTT (z.B.: 0) |
---|
152 | * - textureUnit for blendmap (z.B.: 1) |
---|
153 | * - screenNum |
---|
154 | * - slaveCam projectionOffset (wird mit der vom master multipliziert und auf die slave cam angewendet, meist identity) |
---|
155 | * - slaveCam viewOffset (wird mit der vom master multipliziert und auf die slave cam angewendet, verwendet für translation und rotation offset) |
---|
156 | * |
---|
157 | * need to add setter/getter as well as the serializer macros. |
---|
158 | * |
---|
159 | * |
---|
160 | * osgViewer load and apply distortion (apply via setupDistortion(...) |
---|
161 | * setUpIntensityMapBlending(string filepath, int rrtTexUnit=1, int scenTexUnit=0): simple function providing a file path, and optionally the texUnits to use. Wil invoke the more detailed funtion for setup. |
---|
162 | * setUpIntensityMapBlending(osg::StateSet* stateset, osg::Image* intensityMap, unsigned int screenNum, int rttSceneTextureUnit, int intensityMapTextureUnit) |
---|
163 | * |
---|
164 | * |
---|
165 | * distortionManipulator abgeleitet von osgGA::GUIEventHandler |
---|
166 | * Grundfunktionen: |
---|
167 | * [done] - Key to Show Distortion Mesh / Intensity Map / none |
---|
168 | * - Key to Save distortion Container - via plugin |
---|
169 | * [done] - Key to toggle MANUAL mode between blending und distortion setup |
---|
170 | * [done] - Key to toggle distortion setup: |
---|
171 | * 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) |
---|
172 | * MANUAL distortion/blending modification via mouse Selection and drag'n'drop |
---|
173 | * DELEGATED distortion/blending modification by calling a foreign class or calling a subclassed function |
---|
174 | * [done] - Key to control if mouse drags affects mesh coordinates or rttScene texture coordinates. Default: Mesh coordinates. |
---|
175 | * - Key to reset Distortion. |
---|
176 | * - Key to reset Blending. |
---|
177 | * |
---|
178 | * Die Funktion handle( const osgGA::GUIEventAdapter& ea, osgGA::GUIActionAdapter& aa ): |
---|
179 | * DISABLED: ignorieren |
---|
180 | * MANUAL : auf mouse selection und drags horchen und auf Distortion Anwenden. bei keys die obigen funktionen realisieren |
---|
181 | * DELEGATED : beim typ FRAME die Distortion zur Veränderung stellen indem der Pointer an die bearbeitende Funktion übergeben wird: |
---|
182 | * subsclassed function aufrufen bzw foreignClass->delegateDistortionSetup(distContainer& container) |
---|
183 | * |
---|
184 | * Vertex Highlighter für die manuelle Verzerrung soll nur eingeblendet werden wenn der Betriebsmodus MANUAL ist. |
