Detailed Description

Simple class for wrapping up the data used in glProgramBinary and glGetProgramBinary. On the first run of your application Programs should be assigned an empty ProgramBinary. Before your application exits it should retrieve the program binary via Program::PerContextProgram::compileProgramBinary and save it to disk. When your application is run subsequently, load your binary from disk and use it to set the data of a ProgramBinary, and set the ProgramBinary on the associated Program. This will typically result in Program::compileGLObjects executing much faster.

Constructor & Destructor Documentation

osg::Program::ProgramBinary::ProgramBinary ( )
osg::Program::ProgramBinary::ProgramBinary ( const ProgramBinary rhs,
const osg::CopyOp copyop = osg::CopyOp::SHALLOW_COPY 
)

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

void osg::Program::ProgramBinary::assign ( unsigned int  size,
const unsigned char *  data 
)
Allocated a data buffer of specified size/*/

void allocate(unsigned int size);

/** Assign program binary data, copying the specified data into locally stored data buffer, the original data can then be deleted.

unsigned char* osg::Program::ProgramBinary::getData ( )
inline

Get a ptr to the program binary data.

const unsigned char* osg::Program::ProgramBinary::getData ( ) const
inline

Get a const ptr to the program binary data.

GLenum osg::Program::ProgramBinary::getFormat ( ) const
inline

Get the format of the program binary data.

unsigned int osg::Program::ProgramBinary::getSize ( ) const
inline

Get the size of the program binary data.

osg::Program::ProgramBinary::META_Object ( osg  ,
ProgramBinary   
)
void osg::Program::ProgramBinary::setFormat ( GLenum  format)
inline

Set the format of the program binary data.
