Hi Steven,
yes, you can wrap your GL texture handle with osg::Textire2D object. Here
is some snippet that might help:
<snip>
GLuint handle = ...;
osg::ref_ptr<osg::Texture2D> texture = new osg::Texture2D;
osg::ref_ptr<osg::Texture::TextureObject> textureObject = new
osg::Texture::TextureObject(texture.get(),handle,GL_TEXTURE_2D);
textureObject->setAllocated();
texture->setTextureObject(renderInfo.getContextID(),textureObject.get());
state.setActiveTextureUnit(textureStage);
texture->apply( state );
// Tell state about our changes
state.haveAppliedTextureAttribute(textureStage, texture.get());
