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

[Robert Osfield]

Hi Qingjie,

The osgTexture::TextureObject* osg::Texture::getTextureObject(uint
contextID)  method can be used to get the OSG's wrapper for the OpenGL
texture object.  The TextureObject::id() method returns the OpenGL texture
object id.

Robert.
