[PyOpenGL-Users] Help with VAOs

[Johannes B. <dfn...@gm...>]

Hello list,

I'm trying to store objects (currently only vertices) on the graphics
card so that I can avoid lots of:

glBegin()
glVertex(...)
[...]
glEnd()

I've tried lots and lots of code now (none of which fully did what I
wanted) and really am losing my mind soon :-( I could adapt this to work
with my code:

https://gist.github.com/MorganBorman/4243336

And it does work, but when integrated in my 3D environment I noticed
that the drawn objects are not rendered perspectively, but just a flat
object.

I'm looking for the easiest way to dump a bunch of vertices onto the
graphics card and later reference those vertices to draw some object and
have it render as if I had used glBegin(), glVertex(), glEnd(). Is this
possible at all? Which approach should I look into?

In general I've seen two different approaches, one that involes (usually
super-primitive) shaders, others do not. I do not see why I would need a
custom-shader for this task, is this really necessary?

My goal ultimately is to store surfaces (i.e. vertices, their normals,
their texture UV coordinates) on the graphics card.

Any help is greatly appreciated,
Johannes

[Joe <hom...@gm...>]

Hello,

thanks for your reply.
The example is working now, I replaced the buffers entry
with int(<vbo>) as you suggested.

But after that I ran into another problem, which I found
a solution for but I don't know why it works.

Here again the link to the example:
https://gitorious.org/openclgltest/openclgltest/source/7b9969ef093e7bc04100a860588e6bb115731d97:testpyopengl.py#L173

There was a "wrong type" error in the last parameter of the
following calls:

 > 173 gl.glVertexPointer(4, gl.GL_FLOAT, 0, self.arrvbo)
 > 175 gl.glColorPointer(4, gl.GL_FLOAT, 0, self.colvbo)

I did not know what to do and changed it to "None":

 > 173 gl.glVertexPointer(4, gl.GL_FLOAT, 0, None)
 > 175 gl.glColorPointer(4, gl.GL_FLOAT, 0, None)

and that worked. But I have absolutly no idea why.
Why do the functions know where the vertices / colors
are as I do not specify a pointer to the VBO?

Has it something to do with the .bind() calls of the VBO
before glVertexPointer / glColorPointer?

 > self.arrvbo.bind()
 > gl.glVertexPointer(4, gl.GL_FLOAT, 0, self.arrvbo)

 > self.colvbo.bind()
 > gl.glColorPointer(4, gl.GL_FLOAT, 0, self.colvbo)

Kind regards,
Joe

Re: [PyOpenGL-Users] Compressed Textures

[Alejandro S. <as...@gm...>]

Hi Mike,

Thank you for your answer. I ended up finding the problem, but realized
that maybe my description wasn't as accurate as I thought. What I was
trying to do was load a DXT5 compressed texture. That's why I was using
glCompressedTexImage2D. I was not trying to compress a texture.

The problem was caused by the fact that DXT5 textures already include all
their mipmap levels, which is a problem when working with OpenGL because
you are basically expected to supply the mipmap levels one at a time. This
(old) paper I'm linking here describes how to do the math to achieve this:
http://www.oldunreal.com/editing/s3tc/ARB_texture_compression.pdf (C++ code)

Basically the code is trying to access the "buffers" member of the VBO 
object. The OpenGL_accelerate version of the VBO (the cython-implemented 
one) does *not* have a .buffers (list), only a .buffer (int). Probably 
the attributes should be named _buffer and/or _buffers, as they aren't 
normally used by external code, the normal way to get the ID of the VBO 
is int(<vbo>).

HTH,
Mike

I don't see anywhere in your code where you are compressing the content 
with s3tc_dxt5 compression. I believe (though I have no experience using 
compressed textures), that if you're just trying to get the GL to use an 
internal format with compression you need something like:

         glTexImage2D(
             GL_TEXTURE_2D, 0,
             GL_COMPRESSED_RGBA_S3TC_DXT5_EXT, # internal format...
             ix, iy, 0,
             GL_RGBA,
             GL_UNSIGNED_BYTE,
             image
         )

so that the GL will do the compression of the data. Incidentally, 
there's a bug in the handling of uploading compressed texture data 
(refactoring error), a fix for that should go out in the next release.

Sample code here:

http://bazaar.launchpad.net/~mcfletch/openglcontext/trunk/view/head:/tests/nehe6_compressed.py

[PyOpenGL-Users] Compressed Textures

[Alejandro S. <as...@gm...>]

Hey guys,

I'm having trouble figuring out how the binding works for the S3TC
compressed textures extension.

Here's the relevant snippet:

from OpenGL import extensions
if not extensions.hasGLExtension("GL_EXT_texture_compression_s3tc"):

print "Extension GL_EXT_texture_compression_s3tc required for texture
mapping!"
os.abort()

img = pygame.image.load(“diff.png”)
raw = pygame.image.tostring(img, "RGB")

diff_tex = glGenTextures(1)
glBindTexture(GL_TEXTURE_2D, diff_tex)

glCompressedTexImage2DARB(GL_TEXTURE_2D, 0,
GL_COMPRESSED_RGBA_S3TC_DXT5_EXT, img.get_width(), img.get_height(), 0,
len(raw), raw)

This is raising an Invalid Value GL error:

err = 1281,
description = 'invalid value',
baseOperation = glCompressedTexImage2DARB,

According to the GL docs, invalid value is raised if the size parameter
specified does not match the passed-in byte array, which it should, since
it's just a len() of the data. I also tried width * height * 3, but to no
avail.

I'm using pygame to read the image and convert it into a string (byte
array), which works fine with glTextImage2D, but seems to fail for this
extension.

Has any of you ever encountered something similar? I'm pretty sure I must
be missing something related to the binding, but can't seem to figure out
what.

Thanks in advance,
Alejandro.-

[PyOpenGL-Users] Attribute error using PyOpenGL and PyOpenCL

[Walter W. <hom...@gm...>]

Hello,

I came across a problem and hope that you can help me,
since I could not find a solution crawling the net.

I was trying to run some examples to visualize OpenCL
calculations using OpenGL with shared buffers using

Python 3.3
PyOpenGL 3.1.0
PyOpenGL-accelarate 3.1.0
pyopencl 2014.1

The examples are similar, one that might serve as example is
https://gitorious.org/openclgltest/openclgltest

Trying to run this throws the error:

Traceback (most recent call last):
  File ".\testpyopengl.py", line 234, in <module>
    mytest = test()
  File ".\testpyopengl.py", line 91, in __init__
    self.loadclData()
  File ".\testpyopengl.py", line 205, in loadclData
    self.arr_cl = cl.GLBuffer(self.ctx, mf.READ_WRITE,
int(self.arrvbo.buffers[0]))
  File "vbo.pyx", line 177, in OpenGL_accelerate.vbo.VBO.__
getattr__ (D:\Build\PyOpenGL\pyopengl-bzr\OpenGL_accelerate\src\vbo.c:2757)
AttributeError: 'numpy.ndarray' object has no attribute 'buffers'

Here are two things that might be related to the issue:

1.) PyOpenGL 3.1.0b3; Py_buffer on Python3 unsupported
https://sourceforge.net/p/pyopengl/mailman/message/32385909/

2.) This post that mentions that Python 3 might be the problem. Is that the
case?
http://stackoverflow.com/questions/21821045/numpy-getbuffer-causes-attributeerror-module-object-has-no-attribute-getbuff

I found that another example
https://github.com/enjalot/adventures_in_opencl/blob/master/python/part2/part2.py
was trying to fix this like

try:
    self.pos_cl = cl.GLBuffer(self.ctx, mf.READ_WRITE,
int(self.pos_vbo.buffer))
    self.col_cl = cl.GLBuffer(self.ctx, mf.READ_WRITE,
int(self.col_vbo.buffer))
except AttributeError:
    self.pos_cl = cl.GLBuffer(self.ctx, mf.READ_WRITE,
int(self.pos_vbo.buffers[0]))
    self.col_cl = cl.GLBuffer(self.ctx, mf.READ_WRITE,
int(self.col_vbo.buffers[0]))

But changing the example above like this results in

Traceback (most recent call last):

Well, that for now. I hope you have some ideas on how to fix this.

​It's not a tutorial, but many of my supported open source projects have
simple PyOpenGL code for various purposes. For example, this project
<http://geometrian.com/programming/projects/index.php?project=Mandelbrot%20Set>
has reasonably robust and clear shader code.

[PyOpenGL-Users] Updated PyOpenGL in bzr

[Mike C. F. <mcf...@vr...>]

I've updated PyOpenGL in bzr head, the changes are mostly to tweak/fix 
generation, pick up new extensions from the Khronos spec (e.g. OpenGL 
4.5), and remove some redundant code (e.g. manually importing included 
extensions into VERSION extensions).

Feel free to test. Likely this will turn into a point release at some 
point (i.e. 3.1.1), though so far there doesn't seem to be enough there 
to warrant releasing.

Have fun,
Mike

Thanks for your response!
It's now working, there were some gl errors raised by C in my code. I

[PyOpenGL-Users] New user trying tutorial

[Berlioz S. <roc...@gm...>]

I've been interested in attempting to use pyopengl and pygame together to
display 3D images and accelerate my programs.

I figured a logical first step would be to learn a bit about pyopengl, so I
tried the tutorial.

I successfully installed pyopengl on OSX 10.9, and ran the first tutorial.

However, the second (introducing color variations
http://pyopengl.sourceforge.net/context/tutorials/shader_2.html) fails with
a bus error 10.

Is there another tutorial I should follow/what mistake did I make that is
giving me a segfault?

Here is my code:

BaseContext = testingcontext.getInteractive()

from OpenGL.arrays import vbo
from OpenGL.GL import shaders

class TestContext(BaseContext):

                     gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
                     vertex_color = gl_Color;

Carefully.

Basically you need to make sure that your C code is not interfering with 
the Python code. GL state is a monolithic thing, so if your C code is 
modifying the bound VBO, shader, etc while you are rendering then you 
are going to see failures where your Python is attempting to use the 
modified state. You need to ensure that you are always suspending C 
rendering before you enter Python (and suspending it in a known state), 
and then re-enabling C rendering when you are done.

Mike

The tutorial is omitting the creation of an OpenGL context. Using (most) 
GL commands without a context *used* to be possible, but wasn't "valid", 
and later drivers now enforce the "you must have a context" restriction, 
often by segfaulting on Linux/OS-X machines. As a result, you need to 
get a GL context setup with your windowing system before starting to 
call OpenGL commands. Here's how you could do that with Pygame:

import pygame
import pygame.display
pygame.display.init()
SCREEN = pygame.display.set_mode(
     (640,480),
     pygame.OPENGL | pygame.DOUBLEBUF,
)
pygame.display.set_caption("Example")
try:

     # your code...
     from OpenGL.GL import *
     glMatrixMode(GL_PROJECTION)

finally:
     pygame.display.quit()
     pygame.quit()


HTH,
Mike

[Mike L. <mik...@gm...>]

Yup, that failing to set up a context first was the culprit. Thanks!

Re: [PyOpenGL-Users] Segfault with glMatrixMode

​I'm surprised that it segfaults, but it is well known that you need a
graphics context before you try any OpenGL--perhaps that is the issue. You
set a context up with your windowing system of choice.

[PyOpenGL-Users] Segfault with glMatrixMode

[Mike L. <mik...@gm...>]

Hi folks,

I'm looking to do some 2d drawing, so as suggested by this tutorial
(http://basic4gl.wikispaces.com/2D+Drawing+in+OpenGL) I did:

    from OpenGL.GL import *
    glMatrixMode(GL_PROJECTION)

and immediately encounter a segfault. Seems to happen for any of the
valid arguments to glMatrixMode. Any ideas on what's up? Below is my
system description.

Mac OS 10.9.4
python 2.7.8, installed via brew
PyOpenGL-3.1.0, installed via pip
Report log here: http://pastebin.com/ie2XBfwm

Let me know if there's anything else I should include.

[PyOpenGL-Users] sharing opengl context with c

[amand <am...@fr...>]

Hello!

I'am working on a project in C and I need to draw PyOpenGL stuff with 
embedded python.

So far I have been able to draw with the embedded python. But it does 
not work every time...

Sometimes, the Python module just raises an error (Exception 
OpenGL.error.GLError: GLError( err=1281, description = 'invalid value', 
baseOperation = glVertexAttribPointer)), and some other times, it's 
working perfectly...

Is there a way to share the OpenGL context without any errors?

[PyOpenGL-Users] PyOpenGL 3.1 RPMs for Centos6.2+ and Fedora 19+

[Antoine M. <an...@na...>]

Hi,

Amongst other things, we're having to package PyOpenGL and
PyOpenGL_accelerate 3.1 for CentOS and Fedora.
So I thought this might be of interest to some users on this list.
You can find the spec files we're using here:
http://xpra.org/svn/Xpra/trunk/rpmbuild/
And the (S)RPMs here:
http://xpra.org/dists/CentOS/
http://xpra.org/dists/Fedora/
Let us know if you have any problems.

Cheers

[PyOpenGL-Users] Python 2.4, Pyopgengl 2.0 problem

[Larry C. <cu...@we...>]

Hello Pyopengl folks, 

I'm trying to recreate an old installation of Python 2.4 on Win 7
to run some legacy code. 
(it last ran on Win 2K)

i'm using: 

PyOpenGL-2.0.2.01.py2.4-numpy23.exe

and installed glut32.dll from 
<http://user.xmission.com/%7Enate/glut/glut-3.7.6-bin.zip>glut-3.7.6-bin.zip (117 KB) 
from Nate Robbins' pyopengl page:

some of the opengl demo programs run.
some don't.
and some crash python.exe.
my legacy code also crashes python.exe

whenever python.exe stops working, windows reports:

Fault Module Name:  _GLU__init___.pyd

Is there a known reason why this particular module would
crash Python 2.4?

Is there a fix?

thanks for your help.

Hello,

I installed PyOpenGL and tried the demons. All demos except the one's using
GLE are working. I wanted to mainly use GLE but get following error if I
call any GLE function:

OpenGL.error.NullFunctionError: Attempt to call an undefined function
gleSetJoinStyle, check for bool(gleSetJoinStyle) before calling

I am using a Macbook pro (version 10.8.5). Any help would be appreciated.
