[osg-users] Need help getting the osg::ColorMask I previously set

2008-06-12 Thread Judie 
CODE:


osg::StateSet *stateSet = group-getOrCreateStateSet();


osg::StateSet::AttributeList attributes = stateSet-
getAttributeList();


osg::StateSet::AttributeList::iterator aitr = NULL;


for(aitr= attributes.begin(); aitr!=attributes.end(); ++aitr)
{


osg::StateAttribute::Type temp = (*aitr).first.first;


if(temp == osg::StateAttribute::COLORMASK)
{


osg::ColorMask mask = (*aitr).second.second;


This won't compile. How can I get the osg::ColorMask from the
osg::StateSet::AttributeList::iterator?

Thanks,

Judie

Hi

One things I noticed is you do  'osg::ColorMask mask'. This is wrong you
need this to be a pointer to an osg::ColorMask instance 


FYI If you post a question my code won't compile at least provide the
compilation errors...

osg::Texture2D* texture2D =
dynamic_castosg::Texture2D*(stateset-getTextureAttribute(unit,osg::StateA
ttribute::TEXTURE));
if (texture2D)
  ...

The above is from osgUtil::Optimizer and shows how the TextureAtlasBuilder
gets the Texture2D StateAttribute. You can use a similar method to get any
StateAttribute. For non-texture state, use getAttribute(), for example, and
of course you don't need a 'unit' parameter.
