Hi，
I've also been doing the same thing lately. I've writen some code to
achieve that, maybe help, :)
class TextureVisitor : public osg::NodeVisitor
{
public:
TextureVisitor(int sizelimit, int levelnum):_sizelimit(sizelimit),
_levelnum(levelnum),
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN)
{}
virtual void apply(osg::Group node)
{
osg::StateSet* ss = node.getStateSet();
if(ss!=NULL)
traverseTexture(ss);
traverse(node);
}
virtual void apply(osg::Node node)
{
osg::StateSet* ss = node.getStateSet();
if(ss!=NULL)
traverseTexture(ss);
traverse(node);
}
virtual void apply(osg::Geode node)
{
osg::StateSet* ss = node.getStateSet();
if(ss!=NULL)
traverseTexture(ss);
int numdrawables = node.getNumDrawables();
for(int i=0; inumdrawables; ++i)
{
ss = node.getDrawable(i)-getStateSet();
if(ss!=NULL)
traverseTexture(ss);
}
traverse(node);
}
void traverseTexture(osg::StateSet* ss)
{
osg::StateSet::TextureAttributeList texAbl =
ss-getTextureAttributeList();
int i=0;
for(osg::StateAttribute* sa = ss-getTextureAttribute(i,
osg::StateAttribute::TEXTURE);
itexAbl.size(); ++i)
{
osg::Texture2D* tex2d = dynamic_castosg::Texture2D*(sa);
if(tex2d==NULL)
continue;
//对于每一个image
int numImg = tex2d-getNumImages();
for(int j=0; jnumImg; ++j)
{
osg::Image* img = tex2d-getImage(j);
SaveTexture(img);
}
}
}
string getName(const string filename)
{
string::size_type pos = filename.find_last_of(\\);
string::size_type pointpos = filename.find_last_of(.);
string name;
for(string::size_type i = pos+1; ipointpos; ++i)
{
name += filename[i];
}
return name;
}
void SaveTexture(osg::Image* img)
{
osgDB::writeImageFile(img, img-getFileName());
}
private:
int _sizelimit;
int _levelnum;
};

Hi,
I have a model in .ive format with an embedded texture. I need to bring
the model into 3dsMax to work on it. I can use osgconv to convert it to
one of several different formats that Max can import (obj, dae, etc.),
but I also need the texture that is embedded. Can anyone point me in the
right direction as to how to extract a texture that is embedded in an
.ive file?
Thanks,
Doug
