Hello Per,

To that end, there is a utility function in the Geometry header.
#include <osg/Geometry>
osg::Geode* createNodeWithMyImageOnIt(const std::string& filename)
{
osg::Geode* geode = new osg::Geode;
osg::Geometry* geometry =
osg::createTexturedQuadGeometry(osg::Vec3(0,0,0),
osg::Vec3(1,0,0),
osg::Vec3(0,0,1),
0, 0, 1, 1);
geode->addDrawable(geometry);
osg::Texture2D* texture =
new osg::Texture2D(osgDB::readImageFile(filename));
geode->getOrCreateStateSet()->setTextureAttributeAndModes(0,
texture, osg::StateAttribute::ON);
geode->getOrCreateStateSet()->setTextureMode(0, GL_TEXTURE_2D,
osg::StateAttribute::ON);
return geode;
}
Note this is off the top of my head, untested, possibly incomplete. But
it should give you an idea. Look up the doxygen for
osg::createTexturedQuadGeometry for details.
Hope this helps,
J-S
