| virtual bool osg::BufferObject::isSameKindAs | ( | const Object * | obj | ) | const [inline, virtual] |
Reimplemented from osg::Object.
| virtual const char* osg::BufferObject::libraryName | ( | ) | const [inline, virtual] |
return the name of the object's library.
Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.
Implements osg::Object.
| virtual const char* osg::BufferObject::className | ( | ) | const [inline, virtual] |
return the name of the object's class type.
Must be defined by derived classes.
Implements osg::Object.
| void osg::BufferObject::setUsage | ( | GLenum | usage | ) | [inline] |
Set what type of usage the buffer object will have.
Options are: GL_STREAM_DRAW, GL_STREAM_READ, GL_STREAM_COPY, GL_STATIC_DRAW, GL_STATIC_READ, GL_STATIC_COPY, GL_DYNAMIC_DRAW, GL_DYNAMIC_READ, or GL_DYNAMIC_COPY.
| GLenum osg::BufferObject::getUsage | ( | ) | const [inline] |
Get the type of usage the buffer object has been set up for.

| virtual void osg::BufferObject::compileBuffer | ( | State & | state | ) | const [pure virtual] |
Implemented in osg::VertexBufferObject, osg::ElementBufferObject, and osg::PixelBufferObject.
| virtual void osg::BufferObject::resizeGLObjectBuffers | ( | unsigned int | maxSize | ) | [virtual] |
Resize any per context GLObject buffers to specified size.
Reimplemented from osg::Object.
Reimplemented in osg::VertexBufferObject, osg::ElementBufferObject, and osg::PixelBufferObject.
| void osg::BufferObject::releaseGLObjects | ( | State * | state = 0 |
) | const [virtual] |
If State is non-zero, this function releases OpenGL objects for the specified graphics context.
Otherwise, releases OpenGL objexts for all graphics contexts.
Reimplemented from osg::Object.
| static void osg::BufferObject::deleteBufferObject | ( | unsigned int | contextID, | |
| GLuint | globj | |||
| ) | [static] |
Use deleteVertexBufferObject instead of glDeleteBuffers to allow OpenGL buffer objects to be cached until they can be deleted by the OpenGL context in which they were created, specified by contextID.
| static void osg::BufferObject::flushDeletedBufferObjects | ( | unsigned int | contextID, | |
| double | , | |||
| double & | availableTime | |||
| ) | [static] |
flush all the cached display list which need to be deleted in the OpenGL context related to contextID.
| static Extensions* osg::BufferObject::getExtensions | ( | unsigned int | contextID, | |
| bool | createIfNotInitalized | |||
| ) | [static] |
Function to call to get the extension of a specified context.
If the Exentsion object for that context has not yet been created and the 'createIfNotInitalized' flag been set to false then returns NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object is only created with the graphics context associated with ContextID..
| static void osg::BufferObject::setExtensions | ( | unsigned int | contextID, | |
| Extensions * | extensions | |||
| ) | [static] |
setExtensions allows users to override the extensions across graphics contexts.
typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.
