I'm a user of PyOpenGL working on Linux/OS X. Yesterday I decided to
test PyOpenGL 3-ctypes on OS X.
The test machine is an old Powerbook Titanium G4 667 running 10.3.9! I
took the CVS version of PyOpenGL and compile the latest version
(1.0.3-2) of Numpy.
tests.py ran without problem:
Ran 10 tests in 3.793s
OK
And I took the time to test the demo files. Here are the results:
OpenGL/Demo
GLE/cone.py YES
GLE/helix.py YES
GLE/texas.py YES
GLUT/gears.py YES
GLUT/molehill.py YES
GLUT/tom/arraytest.py YES
GLUT/tom/checker.py YES
GLUT/tom/cone.py YES
GLUT/tom/conechecker.py YES
GLUT/tom/conesave.py YES
GLUT/tom/lorentz.py NO (Bus error)
GLUT/tom/text.py YES
NeHe/lesson1.py YES
NeHe/lesson2.py YES
NeHe/lesson3.py YES
NeHe/lesson4.py YES
NeHe/lesson5.py YES
NeHe/lesson6.py YES
NeHe/lesson6-multi.py YES
NeHe/lesson13.py (win32 specific)
NeHe/lesson18.py YES (but "L" doesn't change lightning)
NeHe/lesson41.py YES
NeHe/lesson42.py YES (but slow, maybe that's normal!)
NeHe/lesson43/lesson43.py NO (ValueError: Unable to locate true type
font 'Test.ttf' but the font is there?)
NeHe/lesson44/lesson44.py DON'T KNOW (The flare is visible only when
the end of the cylinder face the screen?)
NeHe/lesson45.py YES (after adding Terrain.bmp to the directory, it
was not there)
I also test one of my project and I think I found a bug in
glGenTextures. If I'm not wrong, glGenTextures is suppose to return an
array of GLuint. But when you generates only one texture it return a
GLuint and when you generates more then one it returns an array of
numpy.uint32 ?
I can resume the two cases with this code:
CASE 1
...init
textures = glGenTextures(1)
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])
File "./test.py", line 164, in ?
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])
TypeError: unsubscriptable object
CASE 2
...init
textures = glGenTextures(2)
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])
File "./test.py", line 164, in ?
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])
ctypes.ArgumentError: argument 2: exceptions.TypeError: wrong type
BUT if you do this, it works...
...init
textures = glGenTextures(1)
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures)
Have an idea ? The problem is probably in the def of glGenTextures in
exceptions.py but I don't understand "annotations". So I was not able
to patch it.
Also I did a new extension (a really easy one!)
OpenGL.GL.EXT.texture_rectangle.
If you're curious, here is the project I did with PyOpenGL:
