Detailed Description

OverlayNode is for creating texture overlays on scenes, with the overlay texture being generated by pre rendering an Overlay Subgraph to a texture, then projecting this resulting texture on the scene.

void osgSim::OverlayNode::init_VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY ( )
protected

◆ META_Node()

osgSim::OverlayNode::META_Node ( osgSim  ,
OverlayNode   
)

◆ releaseGLObjects()

virtual void osgSim::OverlayNode::releaseGLObjects ( osg::State = 0) const
virtual

If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objexts for all graphics contexts.

Reimplemented from osg::Group.

◆ resizeGLObjectBuffers()

virtual void osgSim::OverlayNode::resizeGLObjectBuffers ( unsigned int  )
virtual

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Group.

◆ setContinuousUpdate()

void osgSim::OverlayNode::setContinuousUpdate ( bool  update)
inline

Set whether the OverlayNode should update the overlay texture on every frame.

◆ setOverlayBaseHeight()

void osgSim::OverlayNode::setOverlayBaseHeight ( double  baseHeight)
inline

Set the base height that the overlay subgraph will be projected down to. Normally you'll set this to just below ground level, if you set it too high then the overlay texture can end up being clipped in certain viewing directions, while if its too low then there will be a limit to how close you can get to the terrain before pixaltion becomes an issue.

◆ setOverlayClearColor()

void osgSim::OverlayNode::setOverlayClearColor ( const osg::Vec4 color)
inline

Set the clear color to use when rendering the overlay subgraph.

◆ setOverlaySubgraph() [1/2]

Set the overlay subgraph which will be rendered to texture.

◆ setOverlayTechnique()

void osgSim::OverlayNode::setOverlayTechnique ( OverlayTechnique  technique)

◆ setOverlayTextureSizeHint()

void osgSim::OverlayNode::setOverlayTextureSizeHint ( unsigned int  size)

Set the texture size hint. The size hint is used to request a texture of specified size.

◆ setOverlayTextureUnit()

void osgSim::OverlayNode::setOverlayTextureUnit ( unsigned int  unit)

Set the texture unit that the texture should be assigned to.

◆ setRenderTargetImplementation()

void osgSim::OverlayNode::setRenderTargetImplementation ( osg::Camera::RenderTargetImplementation  impl)

Set the implementation to be used when creating the overlay texture.

◆ setTexEnvMode()

void osgSim::OverlayNode::setTexEnvMode ( GLenum  mode)

Set the TexEnv mode used to combine the overlay texture with the base color/texture of the OverlayNode's decorate subgraph.

◆ setThreadSafeRefUnref()

virtual void osgSim::OverlayNode::setThreadSafeRefUnref ( bool  threadSafe)
virtual

Set whether to use a mutex to ensure ref() and unref() are thread safe.

Reimplemented from osg::Group.

◆ traverse()

virtual void osgSim::OverlayNode::traverse ( osg::NodeVisitor )
virtual

Traverse downwards : calls children's accept method with NodeVisitor.
