use deleteFragmentProgramObject instead of glDeletePrograms to allow OpenGL Fragment Program objects to be cached until they can be deleted by the OpenGL context in which they were created, specified by contextID. | |
static void | flushDeletedFragmentProgramObjects (unsigned int contextID, double currentTime, double &availableTime) |

osg::FragmentProgram::FragmentProgram | ( | ) |
osg::FragmentProgram::FragmentProgram | ( | const FragmentProgram & | vp, |
const CopyOp & | copyop = CopyOp::SHALLOW_COPY |

Copy constructor using CopyOp to manage deep vs shallow copy.
virtual osg::FragmentProgram::~FragmentProgram | ( | ) | [protected, virtual] |
virtual void osg::FragmentProgram::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::FragmentProgram::compare | ( | const osg::StateAttribute & | sa | ) | const [inline, virtual] |
return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.
Implements osg::StateAttribute.

virtual void osg::FragmentProgram::compileGLObjects | ( | State & | ) | const [inline, virtual] |
Default to nothing to compile - all state is applied immediately.
Reimplemented from osg::StateAttribute.
static void osg::FragmentProgram::deleteFragmentProgramObject | ( | unsigned int | contextID, |
GLuint | handle | ||
) | [static] |
use deleteFragmentProgramObject instead of glDeletePrograms to allow OpenGL Fragment Program objects to be cached until they can be deleted by the OpenGL context in which they were created, specified by contextID.
void osg::FragmentProgram::dirtyFragmentProgramObject | ( | ) |
Force a recompile on next apply() of associated OpenGL vertex program objects.
static void osg::FragmentProgram::discardDeletedFragmentProgramObjects | ( | unsigned int | contextID | ) | [static] |
discard all the cached fragment 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::FragmentProgram::flushDeletedFragmentProgramObjects | ( | unsigned int | contextID, |
double | currentTime, | ||
double & | availableTime | ||
) | [static] |
flush all the cached fragment programs which need to be deleted in the OpenGL context related to contextID.
static Extensions* osg::FragmentProgram::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 has 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..

Get the fragment program.
GLuint& osg::FragmentProgram::getFragmentProgramID | ( | unsigned int | contextID | ) | const [inline] |

release an OpenGL objects in specified graphics context if State object is passed, otherwise release OpenGL objects for all graphics context if State object pointer == NULL.
Reimplemented from osg::StateAttribute.
virtual void osg::FragmentProgram::resizeGLObjectBuffers | ( | unsigned int | maxSize | ) | [virtual] |
Resize any per context GLObject buffers to specified size.
Reimplemented from osg::StateAttribute.
static void osg::FragmentProgram::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.

Set the fragment program using a C style string.
