OpenGL scene rendering & multi-threading

A descendant of a TCustomControl object renders an OpenGL scene when its
Paint method is called. The rendering of the scene take some time. How
can I put the scene rendering in a second thread so that the user can
continue working while rendering occurs?

Thanks!

Best regards

Re:OpenGL scene rendering & multi-threading

There is no continued working when the renderer uses the power.
Either the rendering is done(mostly) in hardware, then it goes quick
and no second thread is required, or it is done mostly in software,
and any other action just slows it down more.
