QUESTION
I am porting some WebGL code in node/javascript to PyOpenGL code in python3. Although the python code does open an OpenGL window, it does not display the rectangle with the grid pattern. I have reduced the program to its minimum for troubleshooting, but cannot find the problem. Any ideas/pointers?
Below the python code and below that the original javascript code.
Python3:

is treated as a byte offset into the buffer object's data store. But the type of the parameter has to be a pointer.
In your case the offset is 0. This means, either you have to use the built-in constant None
QUESTION
I am trying to port hackathon-slicer to python3 with the OpenGL library. The hackathon slicer is programmed in node/javascript and runs fine on my older laptop.
However when I port it to python using the OpenGL library, I get an error on 'glGenFramebuffers' because glGenFramebuffers is not available. I checked and the OpenGL library has the function available. Also since it runs fine in node/javascript my laptops graphics card also has FrameBuffer available.
So what is the real problem and how to solve this? Any help greatly appreciated!
