Hi,
I have been learning the OSG for two months.As the need of my project,I would
like to combine the OSG and OpenGL in MFC.In my programme,using the OpenGL
draws the background(such as Terrain) in the main thread and the OSG draws the
surface features(such as buildings) in the sub thread.When I run my programme,I
found the result is normal in the first frame,however,from the second frame,It
can't clear the window and leaves the traces of the previous frame.I know that
It can be implemented by using the preDrawCallback,but the method does not meet
the requirement drawing the background in the main thread.I have no idea how to
do it.Do you have a solution to realize this situation? Please help me.
Thank you!
Best,
xulie
