Constructor & Destructor Documentation

osg::VertexProgram::VertexProgram ( )
osg::VertexProgram::VertexProgram ( const VertexProgram vp,

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.

References COMPARE_StateAttribute_Parameter, and COMPARE_StateAttribute_Types.

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

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

Reimplemented from osg::StateAttribute.

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.

static Extensions* osg::VertexProgram::getExtensions ( unsigned int  contextID,
bool  createIfNotInitalized 
)
static

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.

LocalParamList& osg::VertexProgram::getLocalParameters ( )
inline

Get list of Program Parameters

const LocalParamList& osg::VertexProgram::getLocalParameters ( ) const
inline

Get const list of Program Parameters

MatrixList& osg::VertexProgram::getMatrices ( )
inline

Get list of Matrices

const MatrixList& osg::VertexProgram::getMatrices ( ) const
inline

Get list of Matrices

virtual bool osg::VertexProgram::getModeUsage ( StateAttribute::ModeUsage ) const
inlinevirtual

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

References GL_VERTEX_PROGRAM_ARB, and osg::StateAttribute::ModeUsage::usesMode().

const std::string& osg::VertexProgram::getVertexProgram ( ) const
inline

Get the vertex program.

GLuint& osg::VertexProgram::getVertexProgramID ( unsigned int  contextID) const
inline

Get the handle to the vertex program ID for the current context.

osg::VertexProgram::META_StateAttribute ( osg  ,
VertexProgram  ,
VERTEXPROGRAM   
)
virtual void osg::VertexProgram::releaseGLObjects ( State state = 0) const
virtual

Release any OpenGL objects in specified graphics context if State object is passed, otherwise release OpenGL objects for all graphics contexts if State object pointer is NULL.

Reimplemented from osg::StateAttribute.

virtual void osg::VertexProgram::resizeGLObjectBuffers ( unsigned int  maxSize)
virtual

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::StateAttribute.

static void osg::VertexProgram::setExtensions ( unsigned int  contextID,
Extensions extensions 
)
static

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.

void osg::VertexProgram::setLocalParameters ( const LocalParamList lpl)
inline

Set list of Program Parameters

void osg::VertexProgram::setMatrices ( const MatrixList matrices)
inline

Set list of Matrices

void osg::VertexProgram::setMatrix ( const GLenum  mode,
const Matrix matrix 
)
inline

Matrix

void osg::VertexProgram::setProgramLocalParameter ( const GLuint  index,
const Vec4 p 
)
inline

Set Program Parameters

void osg::VertexProgram::setVertexProgram ( const char *  program)
inline

Set the vertex program using a C style string.

void osg::VertexProgram::setVertexProgram ( const std::string &  program)
inline

Set the vertex program using C++ style string.
