Inheritance diagram for osg::GraphicsContext:
| osg::GraphicsContext::GraphicsContext | ( | ) | [protected] |
| virtual osg::GraphicsContext::~GraphicsContext | ( | ) | [protected, virtual] |
| void osg::GraphicsContext::bindPBufferToTexture | ( | GLenum | buffer | ) | [inline] |
Bind the graphics context to associated texture.
| virtual void osg::GraphicsContext::bindPBufferToTextureImplementation | ( | GLenum | buffer | ) | [pure virtual] |
Pure virtual, Bind the graphics context to associated texture implementation. Pure virtual - must be implemented by concrate implementations of GraphicsContext.
Implemented in osgProducer::GraphicsContextImplementation.
| void osg::GraphicsContext::close | ( | bool | callCloseImplementation = true |
) |
close the graphics context. close(bool) stops any associated graphics threads, releases the contextID for the GraphicsContext then optional calls closeImplementation() to do the actual deletion of the graphics. This call is made optional as there are times when the graphics context has already been deleted externally and only the OSG side of the its data need to be closed down.
| virtual void osg::GraphicsContext::closeImplementation | ( | ) | [pure virtual] |
Close the graphics context implementation. Pure virtual - must be implemented by concrate implementations of GraphicsContext.
Implemented in osgProducer::GraphicsContextImplementation.
| static GraphicsContext* osg::GraphicsContext::createGraphicsContext | ( | Traits * | traits | ) | [static] |
Create a graphics context for a specified set of traits.
| void osg::GraphicsContext::createGraphicsThread | ( | ) |
Create a graphics thread to the graphics context, so that the thread handles all OpenGL operations.
| static unsigned int osg::GraphicsContext::createNewContextID | ( | ) | [static] |
Create a contextID for a new graphics context, this contextID is used to set up the osg::State associate with context. Automatically increments the usage count of the contextID to 1.
| static void osg::GraphicsContext::decrementContextIDUsageCount | ( | unsigned int | contextID | ) | [static] |
Decrement the usage count associate with a contextID. Once the contextID goes to 0 the contextID is then free to be reused.
| static CreateGraphicContextCallback* osg::GraphicsContext::getCreateGraphicsContextCallback | ( | ) | [static] |
Get the create graphics context callback
| const GraphicsThread* osg::GraphicsContext::getGraphicsThread | ( | ) | const [inline] |
Get the const graphics thread assigned the graphics context.
| GraphicsThread* osg::GraphicsContext::getGraphicsThread | ( | ) | [inline] |
Get the graphics thread assigned the graphics context.
| const State* osg::GraphicsContext::getState | ( | ) | const [inline] |
Get the const State object which tracks the current OpenGL state for this graphics context.
| State* osg::GraphicsContext::getState | ( | ) | [inline] |
Get the State object which tracks the current OpenGL state for this graphics context.
| const Traits* osg::GraphicsContext::getTraits | ( | ) | const [inline] |
Get the traits of the GraphicsContext.
| static void osg::GraphicsContext::incrementContextIDUsageCount | ( | unsigned int | contextID | ) | [static] |
Increment the usage count associate with a contextID. The usage count speficies how many graphics contexts a specific contextID is shared between.
| bool osg::GraphicsContext::isCurrent | ( | ) | const [inline] |
Return true if the current thread has this OpenGL graphics context.
| bool osg::GraphicsContext::isRealized | ( | ) | const [inline] |
Return true if the graphics context has been realised and is ready to use.
| virtual bool osg::GraphicsContext::isRealizedImplementation | ( | ) | const [pure virtual] |
Return true if the graphics context has been realised, and is ready to use, implementation. Pure virtual - must be implemented by concrate implementations of GraphicsContext.
Implemented in osgProducer::GraphicsContextImplementation.
| void osg::GraphicsContext::makeContextCurrent | ( | GraphicsContext * | readContext | ) |
Make this graphics context current with specified read context. Implementated by first aquiring a lock of the GraphicsContext mutex, and then doing a call to makeContextCurrentImplementation().
| virtual void osg::GraphicsContext::makeContextCurrentImplementation | ( | GraphicsContext * | readContext | ) | [pure virtual] |
Make this graphics context current with specified read context implementation. Pure virtual - must be implemented by concrate implementations of GraphicsContext.
Implemented in osgProducer::GraphicsContextImplementation.
| void osg::GraphicsContext::makeCurrent | ( | ) |
Make this graphics context current. Implementated by first aquiring a lock of the GraphicsContext mutex, and then doing a call to makeCurrentImplementation().
| virtual void osg::GraphicsContext::makeCurrentImplementation | ( | ) | [pure virtual] |
Make this graphics context current implementation. Pure virtual - must be implemented by concrate implementations of GraphicsContext.
Implemented in osgProducer::GraphicsContextImplementation.
| bool osg::GraphicsContext::realize | ( | ) |
Realise the GraphicsContext.
| virtual bool osg::GraphicsContext::realizeImplementation | ( | ) | [pure virtual] |
Realise the GraphicsContext implementation, Pure virtual - must be implemented by concrate implementations of GraphicsContext.
Implemented in osgProducer::GraphicsContextImplementation.
| void osg::GraphicsContext::releaseContext | ( | ) |
Release the graphics context by unlocking the GraphicsContext mutex.
| static void osg::GraphicsContext::setCreateGraphicsContextCallback | ( | CreateGraphicContextCallback * | callback | ) | [static] |
Set the create graphics context callback - this callback should be supplied by the windows toolkit.
| void osg::GraphicsContext::setGraphicsThread | ( | GraphicsThread * | gt | ) |
Assign a graphics thread to the graphics context, so that the thread handles all OpenGL operations.
| void osg::GraphicsContext::setState | ( | State * | state | ) | [inline] |
Set the State object which tracks the current OpenGL state for this graphics context.
| void osg::GraphicsContext::swapBuffers | ( | ) |
swap the front and back buffers.
| virtual void osg::GraphicsContext::swapBuffersImplementation | ( | ) | [pure virtual] |
Swap the front and back buffers implementation. Pure virtual - must be implemented by Concrate implementations of GraphicsContext.
