Public Member Functions |
| FragmentProgram () |
| FragmentProgram (const FragmentProgram &vp, const CopyOp ©op=CopyOp::SHALLOW_COPY) |
| Copy constructor using CopyOp to manage deep vs shallow copy.
|
| META_StateAttribute (osg, FragmentProgram, FRAGMENTPROGRAM) |
virtual int | compare (const osg::StateAttribute &sa) const |
| return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.
|
virtual bool | getModeUsage (ModeUsage &usage) const |
| Return the modes associated with this StateAttribute.
|
GLuint & | getFragmentProgramID (unsigned int contextID) const |
| Get the handle to the fragment program id for the current context.
|
void | setFragmentProgram (const std::string &program) |
| Set the fragment program using C++ style string.
|
void | setFragmentProgram (const char *program) |
| Set the fragment program using a C style string.
|
const std::string & | getFragmentProgram () const |
| Get the fragment program.
|
void | setProgramLocalParameter (const GLuint index, const Vec4 &p) |
| Set Program Parameters.
|
LocalParamList & | getLocalParamList () |
| Get list of Program Parameters.
|
const LocalParamList & | getLocalParamList () const |
| Get const list of Program Parameters.
|
void | setMatrix (const GLenum mode, const Matrix &matrix) |
| Matrix.
|
void | dirtyFragmentProgramObject () |
| Force a recompile on next apply() of associated OpenGL vertex program objects.
|
virtual void | apply (State &state) const |
| apply the OpenGL state attributes.
|
virtual void | compileGLObjects (State &state) const |
| default to nothing to compile - all state is applied immediately.
|
virtual void | releaseGLObjects (State *state=0) const |
| release an OpenGL objects in specified graphics context if State object is passed, otherwise release OpenGL objexts for all graphics context if State object pointer == NULL.
|
Static Public Member Functions |
static void | deleteFragmentProgramObject (unsigned int contextID, GLuint handle) |
| 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) |
| flush all the cached fragment programs which need to be deleted in the OpenGL context related to contextID.
|
static Extensions * | getExtensions (unsigned int contextID, bool createIfNotInitalized) |
| Function to call to get the extension of a specified context.
|
static void | setExtensions (unsigned int contextID, Extensions *extensions) |
| setExtensions allows users to override the extensions across graphics contexts.
