Detailed Description

The SoGLRenderCache class is used to cache OpenGL calls.

SoGLRenderCache::SoGLRenderCache ( SoState * state )

Constructor with state being the current state.

SoGLRenderCache::~SoGLRenderCache ( ) [virtual]

Destructor.

void SoGLRenderCache::open ( SoState * state )

Opens the cache. All GL calls will be cached until close() is called.

void SoGLRenderCache::close ( void )

Closes the cache. Should be called after all GL calls.

void SoGLRenderCache::call ( SoState * state )

Executes the cached display list.

int SoGLRenderCache::getCacheContext ( void ) const

Returns the cache context of this cache. This is used to quickly determine if cache can be used for a state.

This method is an extension versus the Open Inventor API.

SbBool SoGLRenderCache::isValid ( const SoState * state ) const [virtual]

Return TRUE if this cache is valid, FALSE otherwise.

Reimplemented from SoCache.

void SoGLRenderCache::addNestedCache ( SoGLDisplayList * child ) [virtual]

Adds a display list which is called from this cache. This is to make sure the child display list isn't destroyed too early.

void SoGLRenderCache::destroy ( SoState * state ) [protected, virtual]

Can be overridden by subclasses to clean up before they are deleted. Default method does nothing.

Reimplemented from SoCache.
