Hi, As shown in the code below, I get the geometry information from the model of Openflight(.flt) format and move the coordinates of the vertices. But the texture doesn't move. How can I move a texture?
**main** Code: ... osg::ref_ptr<osg::Node> model = osgDB::readNodeFile("test/env_cloud.flt"); coneUpdateVisitor coneV; model->accept(coneV); scene->addChild(model); ... **visitor** Code: class coneUpdateVisitor : public osg::NodeVisitor { ... void apply(osg::Geode& geode) { for (unsigned int i = 0; i<geode.getNumDrawables(); ++i) { scene->setUpdateCallback(new coneUpdateCallback(geode.getDrawable(i)->asGeometry())); } } } **callback** Code: class coneUpdateCallback : public osg::NodeCallback { ... _geom->setUseDisplayList(false); ... virtual void operator()(osg::Node*, osg::NodeVisitor* nv) { if (nv->getFrameStamp()) { _coord = dynamic_cast<osg::Vec2Array*>(_geom->getTexCoordArray(0)); for (unsigned int u = 0; u < _coord->size(); u++) { _coord->at(u).x() += 0.01f; } } } } Thank you!
