Detailed Description

The SoGLRenderCache class is used to cache OpenGL calls.

Constructor & Destructor Documentation

◆ SoGLRenderCache()

SoGLRenderCache::SoGLRenderCache ( SoState state)

Constructor with state being the current state.

◆ ~SoGLRenderCache()

SoGLRenderCache::~SoGLRenderCache ( )


Member Function Documentation

◆ open()

void SoGLRenderCache::open ( SoState state)

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

See also

◆ close()

void SoGLRenderCache::close ( void  )

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

See also

◆ call()

void SoGLRenderCache::call ( SoState state)

Executes the cached display list.

See also

◆ getCacheContext()

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.

◆ isValid()

SbBool SoGLRenderCache::isValid ( const SoState state) const

Return TRUE if this cache is valid, FALSE otherwise.

Reimplemented from SoCache.

◆ addNestedCache()

void SoGLRenderCache::addNestedCache ( SoGLDisplayList child)

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

◆ destroy()

void SoGLRenderCache::destroy ( SoState state)

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

Reimplemented from SoCache.
