Hi,
Here it is :
Code:
#include <RenderBox/GLBoxWrappers/GLBoxOsgTexture.h>
#include <GLBox/Texture/Texture.h>
//
MyTexture::MyTexture()
: osg::StateAttribute ()
, p_CustomerTexture (NULL)
{
}
//
MyTexture::MyTexture(CustomerTexture* pCustomerTexture)
: osg::StateAttribute ()
, p_CustomerTexture (NULL)
{
setCustomerTexture(pCustomerTexture);
}
//
MyTexture::MyTexture(const MyTexture& texture, const osg::CopyOp& copyop)
: osg::StateAttribute (texture, copyop)
, p_CustomerTexture (NULL)
{
setCustomerTexture(texture.customerTexture());
}
//

return 1;
}
return -1;
}
//

//
void MyTexture::compileGLObjects(osg::State& /*state*/) const

}
//

}
