Detailed Description

The SoGLRenderCache class is used to cache OpenGL calls.

Constructor & Destructor Documentation

SoGLRenderCache::SoGLRenderCache (SoState * state)Constructor with state being the current state.

SoGLRenderCache::~SoGLRenderCache () [virtual]Destructor.

Member Function Documentation

void SoGLRenderCache::open (SoState * state)Opens the cache. All GL calls will be cached until close() is called.

See also:

close()
call()

void SoGLRenderCache::close (void)Closes the cache. Should be called after all GL calls.

See also:

open()

void SoGLRenderCache::call (SoState * state)Executes the cached display list.

See also:

open()

int SoGLRenderCache::getCacheContext (void) constReturns 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.
