apply the OpenGL state attributes. The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.
Reimplemented from osg::StateAttribute.

Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.
Implements osg::StateAttribute.

Default to nothing to compile - all state is applied immediately.
Reimplemented from osg::StateAttribute.

Use deleteVertexProgramObject instead of glDeletePrograms to allow OpenGL Vertex Program objects to cached until they can be deleted by the OpenGL context in which they were created, specified by contextID.
void osg::VertexProgram::dirtyVertexProgramObject | ( | ) |
Force a recompile on next apply() of associated OpenGL vertex program objects.
|
static |
discard all the cached vertex programs which need to be deleted in the OpenGL context related to contextID. Note, unlike flush no OpenGL calls are made, instead the handles are all removed. this call is useful for when an OpenGL context has been destroyed.

Flush all the cached vertex programs which need to be deleted in the OpenGL context related to contextID.

Function to call to get the extension of a specified context. If the Extension 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 will only be created with the graphics context associated with ContextID.

Resize any per context GLObject buffers to specified size.

The setExtensions method 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.
