Documentation

SceneView is literaly a view of a scene, encapsulating the camera, global state, lights and the scene itself. Provides methods for setting up the view and rendering it.

SceneView()

Constrcut a default scene view

void setDefaults()

Set scene view to use default global state, light, camera and render visitor

void setSceneData(osg::Node* node)

Set the data which to view. The data will typically be an osg::Scene but can be any osg::Node type.

osg::Node* getSceneData()

Get the scene data which to view. The data will typically be an osg::Scene but can be any osg::Node type.

const osg::Node* getSceneData() const

Get the const scene data which to view. The data will typically be an osg::Scene but can be any osg::Node type.

void setViewport(osg::Viewport* viewport)

Set the viewport of the scene view to use specfied osg::Viewport.

void setViewport(int x, int y, int width, int height)

Set the viewport of the scene view to specified dimensions.

const osg::Viewport* getViewport() const

Get the const viewport.

osg::Viewport* getViewport()

Get the viewport.

void getViewport(int& x, int& y, int& width, int& height)

void setCalcNearFar(bool calc)

Set to true if you want SceneView to automatically calculate values for the near/far clipping planes, each frame, set false to use camera's internal near and far planes. Default value is true.

bool getCalcNearFar() const

return true if SceneView automatically caclculates near and far clipping planes for each frame

void setPrioritizeTextures(bool pt)

set whether the draw method should call renderer->prioritizeTexture

bool getPrioritizeTextures() const

get whether the draw method should call renderer->prioritizeTexture

bool projectWindowIntoObject(const osg::Vec3& window, osg::Vec3& object) const

Calculate, via glUnProject, the object coordinates of a window point. Note, current implementation requires that SceneView::draw() has been previously called for projectWindowIntoObject to produce valid values. Consistent with OpenGL windows coordinates are calculated relative to the bottom left of the window. Returns true on successful projection.

bool projectWindowXYIntoObject(int x, int y, osg::Vec3& near_point, osg::Vec3& far_point) const

Calculate, via glUnProject, the object coordinates of a window x,y when projected onto the near and far planes. Note, current implementation requires that SceneView::draw() has been previously called for projectWindowIntoObject to produce valid values. Consistent with OpenGL windows coordinates are calculated relative to the bottom left of the window. Returns true on successful projection.

bool projectObjectIntoWindow(const osg::Vec3& object, osg::Vec3& window) const

Calculate, via glProject, the object coordinates of a window. Note, current implementation requires that SceneView::draw() has been previously called for projectWindowIntoObject to produce valid values. Consistent with OpenGL windows coordinates are calculated relative to the bottom left of the window, whereas as window API's normally have the top left as the origin, so you may need to pass in (mouseX,window_height-mouseY,...). Returns true on successful projection.

inline void setFrameStamp(osg::FrameStamp* fs)

Set the frame stamp for the current frame

inline const osg::FrameStamp* getFrameStamp() const

Set the frame stamp for the current frame
