Re: [osg-users] osg::Texture and stateSets

Hi,
I am already looked at the optimizer.
But still I cannot access my Texture ;(.
stateset.getTextureAttributeList() is always null. Why? 
I can call the geode Name. I can call the Geometry - but no Texture!!!

My OSG File:

Geode {
  DataVariance DYNAMIC
  name cube.osg
  nodeMask 0x
  cullingActive TRUE
  num_drawables 6
  Geometry {
DataVariance DYNAMIC
StateSet {
  DataVariance DYNAMIC
  rendering_hint OPAQUE_BIN
  renderBinMode INHERIT
  GL_CULL_FACE OFF
  GL_LIGHTING ON
  textureUnit 0 {
GL_TEXTURE_2D ON
Texture2D {
  DataVariance STATIC
  file images.jpg
  wrap_s CLAMP
  wrap_t CLAMP
  wrap_r CLAMP
  min_filter LINEAR_MIPMAP_LINEAR
  mag_filter LINEAR
  maxAnisotropy 1
  useHardwareMipMapGeneration TRUE
  unRefImageDataAfterApply FALSE
  internalFormatMode USE_IMAGE_DATA_FORMAT
}
  }
}
..

Some Ideas??

 Hi,
I think osgUtil::optimizer::TextureVisitor should solve your problem.:)
Good luck.

Hi,
I got a Probel with osg Files, the File structure looks like:
Group{
Geode{
Geometry{
StateSet{
Texture{
}
}
}
}
Geode{
Geometry{
StateSet{
Texture{
}
}
}
}
}
The problem is if I try to traverse my SceneGraph I get the names of my geodes, 
but if I check the TextureAttributeList
osg::StateSet::TextureAttributeList texAttrList = stateSet- 
getTextureAttributeList();
this list is empty. Why is this List empty, did I forget something? I want to 
access all Textures!!
Thanks
Ming

Your texture is part of a stateset attached to the Geometry not to the 
Geode. query the geometry for the stateset and not the geode.

I'm having a similar problem. First I developed my own visitor, but then I 
used osgUtil::Optimizer::TextureVisitor, but the method apply(osg::Texture 
texture) is never called. Short code below:

class ImageVisitor2: public osgUtil::Optimizer::TextureVisitor
{
   public:
  std::setosg::Image* images;
  
  ImageVisitor2(): osgUtil::Optimizer::TextureVisitor(true, true, true, 
true, true, 0.0)
  {}
  void apply(osg::Texture texture)
  {
 images.insert(texture.getImage(0));
  }
  void escribirImagenes()
  {
 for_each(images.begin(), images.end(), imagenToDisk);
  }
};
