Hi there,
I was using Python3 with PyOpenGL 3.1.1 partially updating vbos as numpy
array through the slice operator, when I ran into a bug.
1. When figuring out the step size, arrayByCount fails for numpy.float32
in my case and any other numpy data type, as the arg is not an array.
2. I think start and stop was swapped when figuring out when to copy the
whole array
I hope I got the fix right which I attached with the modified vbo.py as
well as the diff.
Axel.
