Re: [PyOpenGL-Users] [SOLVED] glDrawArrays and PyOpenGL 3.0.0a6 anything changed?

I send you a file showing the problem.

python OpenGLTest.py 0 uses float32
python OpenGLTest.py 1 uses float64 and crashes
python OpenGLTest.py 2 uses float64 and glColorPointerd and does not crash.

My platform is windows XP. The problem is present on Python 2.4 and Python 2.5

BTW, glReadPixelsub(x, y, 1, 1, GL_RGBA) returns 'int8' instead of 'uint8' and I
am forced to implement things like:

color = GL.glReadPixelsub(x, y, 1, 1, GL.GL_RGBA)
#workaround a PyOpenGL bug?
if color.dtype == 'int8':
    color = color.astype(numpy.uint8)

Best regards,

Armando
