class OSGGL2_EXPORT osgGL2::ProgramObject

Encapsulates the OpenGL Shading Language ProgramObject

Inheritance:

Public Methods

ProgramObject()

ProgramObject(const ProgramObject& rhs, const osg::CopyOp& copyop=osg::CopyOp::SHALLOW_COPY)

Copy constructor using CopyOp to manage deep vs shallow copy

META_StateAttribute(osgGL2, ProgramObject, PROGRAMOBJECT)

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

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs

virtual void getAssociatedModes(std::vector<GLMode>& ) const

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

virtual void compile(osg::State& state) const

void dirtyProgramObject()

Force a relink on next apply() of associated glProgramObject.

void addShader( ShaderObject* shader )

static void deleteObject(unsigned int contextID, GLhandleARB handle)

use deleteObject instead of glDeleteObject to allow GL2 Objects to cached until they can be deleted by the OpenGL context in which they were created, specified by contextID

static void flushDeletedGL2Objects(unsigned int contextID, double currentTime, double& availableTime)

flush all the cached glProgramObjects which need to be deleted in the OpenGL context related to contextID

Protected Fields

ShaderObjectList _shaderObjectList

mutable PCPOList _pcpoList

Protected Methods

virtual ~ProgramObject()

PerContextProgObj* getPCPO(unsigned int contextID) const

class OSGGL2_EXPORT PerContextProgObj: public osg::Referenced

typedef osg::buffered_value< osg::ref_ptr<PerContextProgObj> > PCPOList
