[osg-users] how to get the handle of opengl texture that corresponds to a OSG::Texture

[Qingjie Zhang]

Hi Robert,
I'm knowing that the RenderInfo->getContextID() can give me the contextID to use in the getTextureObject(uint contextID), but where can I get the RenderInfo? I searched the source code of Texture but did not find that..
Many thanks.
