New issue 16 by paxcalpt: AttributeError: 'module' object has no
attribute 'GL_ALPHA32F_ARB'
http://code.google.com/p/glumpy/issues/detail?id=16

It seems glumpy may have an issue with PyOpenGL 3.0.2a5.
Here's the traceback...

What is your video card ?

Alos, can you tell me what are the available gl.GL_ALPHA* constants you
have in your implementation ?

Hi Nicolas,

The card is a: Intel HD Graphics 3000
Here are the constants:
GL.GL_ALPHA GL.GL_ALPHA8 GL.GL_ALPHA_SCALE
GL.GL_ALPHA12 GL.GL_ALPHA_BIAS GL.GL_ALPHA_TEST
GL.GL_ALPHA16 GL.GL_ALPHA_BITS GL.GL_ALPHA_TEST_FUNC
GL.GL_ALPHA4 GL.GL_ALPHA_INTEGER GL.GL_ALPHA_TEST_REF

You may try with GL.GL_ALPHA16 instead of ALPHA32F but I'm not sure about
the result.

(ALPHA32F is to indicate OpenGL to use 32 bits float internal format (to
get higher precision))

I had the same problem but resolved this by changing GL.GL_ALPHA32_ARB to
GL.GL_ALPHA16 on line 260 in filters.py.

Nicolas, can you tell me what your OpenGL setup is on the Mac that enables
you to use gl.GL_ALPHA32F_ARB?

Like paxcalpt I am also using PyOpenGL 3.0.2a5 on an MBP 8,2 with an AMD
Radeon HD 6750m graphics card with OpenGL version string: 2.1 ATI-7.18.18.

My video card is a NVIDIA one, this may be the main difference.

The "problem" with GL_ALPHA14 is that you're losing some precision but
maybe it is hardly noticeable ?

It has been fixed (see issue 13).

Not fixed for me I'm afraid. I just downloaded 0.2.1 and get this message
on many of the demo programs.

Second this, I get this error message on many of the demos too.
