Member Enumeration Documentation

anonymous enum

anonymous enum

Two bits are stored. Nodes that should be cached will set the DO_AUTO_CACHE bit, nodes that should NOT be cached will set the DONT_AUTO_CACHE bit. By default, DO_AUTO_CACHE is FALSE unless remote rendering is being done. DONT_AUTO_CACHE is FALSE by default. Separators will auto cache if DO_AUTO_CACHE is TRUE and DONT_AUTO_CACHE is FALSE, otherwise they won't auto-cache.

areMipMapsFast()

static bool SoGLCacheContextElement::areMipMapsFast ( SoState *  state )

static

TRUE if mip-mapped textures are known to be fast (fli2011: always returns TRUE nowadays, only kept to keep legacy code working):

copyMatchInfo()

virtual SoElement * SoGLCacheContextElement::copyMatchInfo ( ) const

virtual

Implements SoElement.

get()

static int SoGLCacheContextElement::get ( SoState *  state )

static

init()

virtual void SoGLCacheContextElement::init ( SoState *  state )

virtual

Reimplemented from SoElement.

initClass()

static void SoGLCacheContextElement::initClass ( )

static

matches()

virtual bool SoGLCacheContextElement::matches ( const SoElement *  elt ) const

virtual

Returns TRUE if the widths match in both elements

Implements SoElement.

set()

static void SoGLCacheContextElement::set ( SoState *  state, int  context, bool  is2PassTransparency  )

static

transparency is in effect (as for DELAYED or SORTED blending), which means that caches containing transparent objects may not be valid.
