class OSGUTIL_EXPORT osgUtil::SceneView: public osg::Referenced

SceneView is literaly a view of a scene, encapsulating the camera, global state, lights and the scene itself.

Inheritance:

Public Classes

enum LightingMode

Public Methods

SceneView()

Constrcut a default scene view

void setSceneData(osg::Node* node)

Set the data which to view.

osg::Node* getSceneData()

Get the scene data which to view.

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

Set the viewport of the scene view.

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

Get the viewport of the scene view.

void setDefaults()

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

void setBackgroundColor(const osg::Vec4& color)

Set the background color used in glClearColor().

const osg::Vec4& getBackgroundColor() const

Get the background color

void setGlobalState(osg::GeoState* state)

osg::GeoState* getGlobalState() const

void setLightingMode(LightingMode mode)

LightingMode getLightingMode() const

void setLight(osg::Light* light)

osg::Light* getLight() const

void setCamera(osg::Camera* camera)

osg::Camera* getCamera() const

void setRenderVisitor(osgUtil::RenderVisitor* rv)

osgUtil::RenderVisitor* getRenderVisitor() const

void setLODBias(float bias)

float getLODBias() const

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.

bool getCalcNearFar()

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

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

Calculate, via glUnProject, the object coordinates of a window point.

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.

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

Calculate, via glProject, the object coordinates of a window.

Protected Methods

virtual ~SceneView()

SceneView()

Constrcut a default scene view

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.

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

Set the viewport of the scene view.

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

Get the viewport of the scene view.

void setDefaults()

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

void setBackgroundColor(const osg::Vec4& color)

Set the background color used in glClearColor(). Defaults to an off blue color.

const osg::Vec4& getBackgroundColor() const

Get the background color

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()

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

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.
