[Python-talk] mat3d error

[Labitt, Bruce]

Sorry, I added the periods.  <sheepish grin>

OK, I just found something funky.  I have python spread out over too
places - i.e, I have a python in /usr/lib AND in /usr/lib64 !!!  

I think I'd like it only in lib64.  So I have site-packages in both
locations...

Umm, how do I clean this up?

# ldd /usr/bin/python reveals
   things are in /lib64

But when I used easy_install, it put stuff into 
   /usr/lib/python2.4/site-packages

instead of /usr/lib64/python2.4/site-packages

???

Did you add the periods?  If not, those are floats, not ints.  You can
convert to int as simply as
	int(width)
which truncates the fractional part of the float.

If they are really ints, then you were absolutely right to prefer to
strictly look at the configuration issues.  It would appear that the
array conversion routines in openGL/GL/images.py are breaking something.

good question.  Apparently it is encoding the type info.

"""OpenGL-wide constant types (not OpenGL.GL-specific"""
import ctypes
from OpenGL.constant import Constant

GL_FALSE = Constant( 'GL_FALSE', 0x0 )
GL_TRUE = Constant( 'GL_TRUE', 0x1 )
GL_BYTE = Constant( 'GL_BYTE', 0x1400 )
GL_UNSIGNED_BYTE = Constant( 'GL_UNSIGNED_BYTE', 0x1401 )
GL_SHORT = Constant( 'GL_SHORT', 0x1402 )
GL_UNSIGNED_SHORT = Constant( 'GL_UNSIGNED_SHORT', 0x1403 )
GL_INT = Constant( 'GL_INT', 0x1404 )
GL_UNSIGNED_INT = Constant( 'GL_UNSIGNED_INT', 0x1405 )
GL_FLOAT = Constant( 'GL_FLOAT', 0x1406 )
GL_DOUBLE = Constant( 'GL_DOUBLE', 0x140a )
GL_CHAR = str
GL_HALF_NV = Constant( 'GL_HALF_NV', 0x1401 )
