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