[PyOpenGL-Users] opaque polygons

[Astan C. <st...@al...>]

Hi,
Im trying to make this:

    green = (( 0.0, 1.0, 0.0, 1 ))
    glColor4f( 0, 1, 0, .1 )
    glBegin( GL_POLYGON )
    glMaterialfv( GL_FRONT, GL_EMISSION, green )
    rad = 0.5
    for i in xrange(0,360,5):
        glVertex3f(x1+math.sin(i*math.pi/180.0)*rad , 
y1+math.cos(i*math.pi/180.0)*rad,z1)      
    glEnd( )

 to be opaque. I read that the last part of glColor4f() allows alpha 
channels for transparency levels. I changed it and it still remains 
solid. What am I doing wrong?
Thanks again for any help.
Cheers
Astan

it would be good to have some kind of solution for this, even if it is 
not nice... something that at least works.

Yes, we had a hack that was working for a version or two of py2exe, but 
that seems to be non-functional by recent reports.  The problem really 
should be solved within py2exe, so that it can handle any project that 
uses eggs, but we could use a hack that works in the meantime if anyone 
wants to play with it.

Take care,
Mike

hey,

yeah, I'm not really sure.  I think it's mainly because setuptools
does not work with py2exe.

Re: [PyOpenGL-Users] py2exe with (py)openGL

[Jason W. <ny...@gm...>]

Hi.

How would I use a VBO with PyOpenGL? Is there a cross-platform method of
doing this?
I can do it in C/C++ but not sure how I would do it in PyOpenGL.

Thanks

Re: [PyOpenGL-Users] Shader Language

Re: [PyOpenGL-Users] py2exe with (py)openGL

[R. D. <re...@gm...>]

Hi,

pyopengl 2.x seems to work with py2exe.  Maybe you could use that.  I
haven't heard of anyone getting 3.x working at all with it.

Here's a more recent build of 2.x for python2.5.  It doesn't support
numeric, or togl.

[PyOpenGL-Users] py2exe with (py)openGL

[Astan C. <st...@al...>]

Hi,
Im trying to make a .exe out of a pygame/pyopengl script using py2exe.
The headers of my script looks like this:
import sys
from OpenGL.GL import *
from OpenGL.GLU import *
from OpenGL.arrays import formathandler
formathandler.FormatHandler.chooseOutput( 'ctypesarrays' )
import os, math, random
import pygame
from pygame.locals import *
if sys.platform == 'win32' or sys.platform == 'win64':
    os.environ['SDL_VIDEO_CENTERED'] = '1'

Im using py2exe 0.6.6 and pyopengl 3.0.0b1, and my steup.py file looks 
like this:

#!/usr/bin/env python
from distutils.core import setup
import py2exe
     
setup(console=["script.py"])

And I can make the .exe fine, but when I try to run the .exe, I keep 
getting this error:

Traceback (most recent call last):
  File "script.py", line 2, in <module>
  File "OpenGL\GL\__init__.pyc", line 2, in <module>
  File "OpenGL\raw\GL\__init__.pyc", line 6, in <module>
  File "OpenGL\raw\GL\constants.pyc", line 7, in <module>
  File "OpenGL\platform\__init__.pyc", line 57, in <module>
  File "OpenGL\platform\__init__.pyc", line 53, in _load
RuntimeError: Unable to find an implementation for the 'win32' ('nt') 
platform

I've tried various things like copying the openGL folder to the .exe 
folder and such, but it didnt work. What am I doing wrong here?
Thanks
Astan

[PyOpenGL-Users] PyOpenGL VBO usage

[Jason W. <ny...@gm...>]

Hi

I've been looking into pyOpenGL but I don't know how I would be able to use
VBO's with it since the commands are usually platform specific and also I
don't know how it would work in PyOpengl.
Does PyOpenGL support the OpenGL shader langauge?

Thanks

[PyOpenGL-Users] Shader Language

[Jason W. <ny...@gm...>]

Hi
Does the new version of PyOpenGL support CG shaders, GLSLang and VBO's?

[PyOpenGL-Users] GLUT trouble

[Nate S. <Na...@gw...>]

I am trying to use PyOpenGL and am running into some errors getting even the
most basic program working. For example, this program:
---------------------------------------------
from OpenGL.GL import *
from OpenGL.GLUT import *

def init():
    glClearColor(0, 0, 0, 0)

def display():
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)

glutInit('')
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB)
-------------------------------------------
generates this error:
-------------------------------------------
Traceback (most recent call last):
  File "C:/Python25/Py3D/test2.py", line 12, in <module>
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB)
  File "C:\Python25\Lib\site-packages\OpenGL\platform\baseplatform.py", line
258, in __call__
    self.__name__, self.__name__,
NullFunctionError: Attempt to call an undefined function
glutInitDisplayMode, check for bool(glutInitDisplayMode) before calling
---------------------------------------------
which seems to be referring to this code in
"Python25\Lib\site-packages\OpenGL\platform\baseplatform.py":
---------------------------------------------
def __call__( self, *args, **named ):
        if self.extension and self.load():
            return self( *args, **named )
        else:
            from OpenGL import error
            raise error.NullFunctionError(
                """Attempt to call an undefined function %s, check for
bool(%s) before calling"""%(
                    self.__name__, self.__name__,
                )
            )
-----------------------------------------------
Which appears to tell me that GLUT is not properly installed, which is silly
because GLUT works when I use Microsoft Visual C++ (but who chooses to use
Microsoft Visual C++ when they can use python?). What do I need to do to get
GLUT up on python?

[PyOpenGL-Users] rotating sphere

[Astan C. <st...@al...>]

Hi,
I have attached a sphere 'obiting' around another sphere. Im not sure 
how to rotate properly but what Im trying to achieve is to get the 
second sphere (the green one) rotate around the first one (yellow) but 
always infront of the camera/point of view along the x-axis 
(horizontally). It seems that whatever I try to rotate it, it always 
goes behind the camera. What other values do I have to change?
Thanks again
Astan

[PyOpenGL-Users] Help with first openGL program

[Astan C. <st...@al...>]

Hi,
I have just started to learn about openGL using pyOpenGL because I am 
rather proficient in python.
Im trying to convert the code from http://www.edm2.com/0511/opengl.html 
or http://www.edm2.com/0511/glcol5f.zip
and make it using pyOpenGL. I have made two attempts at it and both 
seems to fail/not display what I expected. I was expecting either a side 
view or a top-down view of the entire solar system instead of the vewing 
from the pole of earth.
Does anyone have any idea how I can change the point of view or camera 
position or what I need to do here? Im not sure how OpenGL does this.
Both my attempts are attached (sorry about the messy code) and both are 
similar to NeHe's tutorials.
Thanks for the help.
Astan

I'm working on a 3d graphics project, and found nice samples for
mat3D.py, which is available from http://www.scipy.org/WilnaDuToit. The
program includes this code:

"""OpenGL-based 3d surface plot"""
#last updated 12/10/2006
from OpenGL.GL import *
from OpenGL.GLUT import *
from OpenGL.Tk import *
import Tkinter

import numpy as N
import tkFileDialog

-snip-

def make_plot(self,colors = Colors):
    """Draw a plot in a Tk OpenGL render window."""
    
    # Some api in the chain is translating the keystrokes to this octal
string
    # so instead of saying: ESCAPE = 27, we use the following.
    ESCAPE = '\033'

    # Number of the glut window.
    window = 0
        
    # Create render window (tk)
    f = Tkinter.Frame()
    f.pack(side = 'top')
    self.offset = 0.05
    self.textlength,self.xticks,self.yticks,self.zticks
=self.GetFormatMaxTextLength() #todo: each tick own offset
    o = Opengl(width = 640, height = 480, double = 1, depth = 1)
    o.redraw = self.redraw

-snip-

which yields the following error:

Traceback (most recent call last):
  File "/home/browerg/text.py", line 35, in <module>
    o = Opengl(None, width = 400, height = 200, double = 1, depth = 1)
NameError: name 'Opengl' is not defined



Searching the web led me to text.py at
http://www.koders.com/python/fid02D8AE6DDE1B87CF36E3766500C78F05AAF6C31C.aspx?s=tkinter#L33. The program includes this code:

#!/usr/bin/env python

from OpenGL.GL import *
from OpenGL.Tk import *

from logo import *

-snip-

import Tkinter, sys

o = Opengl(None, width = 400, height = 200, double = 1, depth = 1)

-snip-

 which gave the same error:

Traceback (most recent call last):
  File "/home/browerg/text.py", line 35, in <module>
    o = Opengl(None, width = 400, height = 200, double = 1, depth = 1)
NameError: name 'Opengl' is not defined


I'm running Python2.5, Tk8.4, and Tcl8.4 on Ubuntu 7.10. Hardware is an
i686 laptop.

What am I missing?

Thanks in advance.

[PyOpenGL-Users] GLUError or GLUerror

[Robert A. <rob...@gm...>]

Hi,

I'm the maintainer for glChess in the gnome-games package and we're
having a problem with the name of the GLU error exception class on
Gentoo.

On my Ubuntu 7.10 box the following works:
>>> import OpenGL.GLU
>>> OpenGL.GLU.GLUError

but on Gentoo it fails, they expect:
>>> import OpenGL.GLU
>>> OpenGL.GLU.GLUerror

What is the correct name for the exception class?

Thanks,
--Robert

[PyOpenGL-Users] import OpenGL.GL not working on windows

[Jason W. <ny...@gm...>]

HI. I am using the latest pyOpenGL for windows and when I type this in
python
import OpenGL.GL
it says that pkg_resources is missing.

I have no clue what I am supposed to do.

Please can you help me

[PyOpenGL-Users] Using gl*Pointer with vertex buffer objects

[Jason T. <ten...@gm...>]

I would like to use a single vertex buffer object to contain information
about vertices, normals, and colors.  According to the GL spec for
glNormalPointer, glVertexPointer, and glColorPointer:

            If a non-zero named buffer object is bound to the
GL_ARRAY_BUFFER target
            (see glBindBuffer) while a normal/vertex/color array is
            specified, pointer is treated as a byte offset into the buffer
object's data store.
            Also, the buffer object binding (GL_ARRAY_BUFFER_BINDING) is
saved as normal vertex array
            client-side state (GL_NORMAL_ARRAY_BUFFER_BINDING).

Is there any way to do this currently?  PyOpenGL seems to expect an actual
sequence for the pointer value.

If there isn't a way of doing this already, I'll poke around and see if I
can't make a patch to support this alternative behavior in my spare time.
Any suggestions about how to go about this patch for PyOpenGL?  (I'm fairly
swift with Python, minimal experience with ctypes, and moderate OpenGL
experience.)

[PyOpenGL-Users] Help

[Sibtey M. <si...@in...>]

Hi All

 

        I am new to PyOpenGl and want to use 2D graphics, to create
rectangle to represent some information. Is there any 2D graphics library
that is supported by pygame and will be a better option instead of using
PyOpenGl?

 

 

 

Thanks,

Sibtey Mehdi

[PyOpenGL-Users] numpy and opengl

[Alan B. <ab...@ve...>]

Is there a simple example in pyopengl that uses numpy to generate a 
display list of verticies?  If so, where can I find it?

I'm happy to say that it is all working great so far, however I just started to include some of the lighting code and its giving me some nasty polygon edges.  Basically, it looks like the normals aren't smoothing across the surface of the object.  See picture here:

glShadeModel(GL_SMOOTH)

will work if you model is defined correctly (i.e., shared vertices share
normals).

[PyOpenGL-Users] Polygon Normal Smoothing?

[Patrick V. P. <pa...@la...>]

Hello!  New user here, with a hopefully simple question.

I'm currently writing an object/animation loader with PyOpenGL, using mostly what is presented in the python-adjusted Nehe tutorials (with some hackery to display calllists like a flipbook).  I'm happy to say that it is all working great so far, however I just started to include some of the lighting code and its giving me some nasty polygon edges.  Basically, it looks like the normals aren't smoothing across the surface of the object.  See picture here:

http://img212.imageshack.us/img212/5102/facetedgd8.jpg

It was at this point that I realized the tutorials all use cubes, which of course have a sharp edge.  Can anyone point me in a direction to get the surface to look like it is a nice smooth surface?  Thanks for any and all help!

PS:  The model was a free one off of Turbosquid that I slapped some quick animation onto.
