Hi,
I have a texture2D, and I want to change its image dynamically. How can I do
it?
I tried:
>
> Create()===>
> osg::ref_ptr<osg::Geode> geode = new osg::Geode;
> geode->addDrawable( osg::createTexturedQuadGeometry(osg::Vec3(),
> osg::Vec3(40.0,0.0,0.0), osg::Vec3(0.0,0.0,40.0)) );
> geode->setDataVariance(osg::Object::DYNAMIC);
> textureLensFlare = new osg::Texture2D;
> textureLensFlare->setImage( im );
> textureLensFlare->setDataVariance(osg::Object::DYNAMIC);
> textureLensFlare->setFilter(osg::Texture::MIN_FILTER,
> osg::Texture::LINEAR_MIPMAP_LINEAR);
> textureLensFlare->setFilter(osg::Texture::MAG_FILTER, osg::Texture::LINEAR);
> textureLensFlare->setWrap(osg::Texture::WRAP_S, osg::Texture::CLAMP);
> textureLensFlare->setWrap(osg::Texture::WRAP_T, osg::Texture::CLAMP);
> geode->getOrCreateStateSet()->setTextureAttributeAndModes(0,
> textureLensFlare, osg::StateAttribute::ON );
> geode->getOrCreateStateSet()->setDataVariance(osg::Object::DYNAMIC);
> geode->getOrCreateStateSet()->setMode(GL_BLEND, osg::StateAttribute::ON);
> geode->getOrCreateStateSet()->setRenderingHint(osg::StateSet::TRANSPARENT_BIN);

But it didn't work. I try with ->dirty() , dirtyTextextureObject(),
->setDaraVariance(osg::Object::DYNAMIC), etc... but no success :(
And another question...What about performance of this method? Approximately, I
will change texture twice each second. Is this a good solution, Or is there any
other better?
Thanks!
