PyOpenGL :: OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling
I’m following this very easy guide in order to make my first steps into PyOpenGL. I installed pip install PyOpenGL PyOpenGL_accelerate , all good. I tested the installation through the test code: import OpenGL.GL import OpenGL.GLUT import OpenGL.GLU print(“Imports successful!”) # If you see …
How am I going wrong in glMultiDrawArraysIndirect function?
I’m programming using Python and Modern OpenGL, and I tried to implement the glMultiDrawArraysIndirect function in my code to draw a simple shape, I want to apply it later on to a more complex thing, but this is just a simple test that I don’t know exactly where the error is. In the VBO there is a…
pyOpenGL 2D Image drawn skewed
I am trying to draw a 2d image in OpenGL using pillow to load the image, but when I render it in OpenGL, the image is skewed. This is the original image: Loading.png This is the code: Result As you can see, the result is a skewed image, I don’t know why this is happening, and I can’t see the
PyOpenGL raises an exception after being frozen using cx_Freeze?
I am making a game in PyOpenGL and want to freeze it using cx_Freeze. But it seems to me that importing PyOpenGL raises an exception in the PyOpenGL module. When I run the frozen script: How can I solve this issue and get PyOpenGL to work? EDIT: For people who don’t have PyOpenGL, the below function sho…
PyOpenGL – Minimal glDrawArrays Example
I’ve seen many minimal PyOpenGL examples, but none of the ones I’ve found make use of VAOs or glDrawArrays / glDrawElements. Instead they all use glVertex, glut shapes, and occasionally the old glCallList function. I’m now trying to write a minimal working example that uses vertex arrays and…
How to rotate slices of a Rubik’s Cube in python PyOpenGL?
I’m attempting to create a Rubik’s Cube in Python, i have gotten as far as visually representing the cube. Struggling a bit with how to implement rotation. I guess i’m asking for feedback as to how to go about doing this. I thought at first of, rotating each cubes set of vertices’s, wi…
