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 ( )

virtual

Destructor.

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()

call()

close()

void SoGLRenderCache::close

(

void

)

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

See also

open()

call()

void SoGLRenderCache::call

(

SoState *

state

)

Executes the cached display list.

See also

open()

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

virtual

Return TRUE if this cache is valid, FALSE otherwise.

Reimplemented from SoCache.

addNestedCache()

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.

destroy()

void SoGLRenderCache::destroy ( SoState *  state )

protectedvirtual

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

Reimplemented from SoCache.
