Member Function Documentation

virtual void osg::VertexProgram::apply ( State &  ) const
virtual

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.

virtual int osg::VertexProgram::compare ( const osg::StateAttribute &  sa) const
inlinevirtual

Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

Implements osg::StateAttribute.

Definition at line 127 of file VertexProgram.h.

virtual void osg::VertexProgram::compileGLObjects ( State &  ) const
inlinevirtual

Default to nothing to compile - all state is applied immediately.

Reimplemented from osg::StateAttribute.

Definition at line 229 of file VertexProgram.h.

static void osg::VertexProgram::deleteVertexProgramObject ( unsigned int  contextID,
GLuint  handle 
)
static

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 void osg::VertexProgram::discardDeletedVertexProgramObjects ( unsigned int  contextID)
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.

static void osg::VertexProgram::flushDeletedVertexProgramObjects ( unsigned int  contextID,
double  currentTime,
double &  availableTime 
)
static

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