I want to draw two rectangles that serve as "robot arms". These should be able to rotate separately around their own axis. The rectangles should lie at the origin of the coordinate system. With the keys 'a' and 'd' the green arm shall be rotated to the left and right, and with the keys 'w' and 's' the blue arm shall be rotated to the left and right. Here is a visual representation of how it should rotate: rotating robot arms

I have already drawn both rectangles and can also move them with the keys. However, I can't get the rotation right. I can't rotate the rectangles separately, they always rotate at the same time and also not around their own axis. Does anyone know how I can do this and what is missing in my code? I have only found questions about how to rotate individual objects, but never two separate objects in one window. (especially not for python + opengl)

Here's my code so far:

I have two different problems occurs at the same time.

I am having dimensionality problems with MaxPooling2d and having same dimensionality problem with DQNAgent.

The thing is, I can fix them seperately but cannot at the same time.

First Problem

I am trying to build a CNN network with several layers. After I build my model, when I try to run it, it gives me an error.

I'm trying to display a STL file using pyopengl VBO but When i try it small amount of vertex list, it works fine. but When trying it with very long data which is loaded from STL file with exact same code, it displays nothing.

for example, with simple vertex data as list

test = [0.5, -0.5, 0.0, 1.0, 0.0, 0.0, -0.5, -0.5, 0.0, 0.0, 1.0, 0.0, 0.0,0.5, 0.0, 0.0, 0.0, 1.0 ]

but with big amount of data is not showing anything.

test = [0.5, -0.5, 1111.0, 1.0, 0.0, 0.0, -0.5, -11111.5, 0.0, 0.0, 1.0, 0.0, 0.0,0.5, 0.0, 0.0, 0.0, 1.0 ]

does someone know about this issue?

So i'm working on a voxel base engine and i'm currently changing from tkinter's canvas to PyOpenGl. I found the function glDrawnPixels who is very important for my engine. But here's the problem, i don't know OpenGL or PyOpenGl so much and my tentative sold with black pixel. So how do i do to have different color of pixel.

Here's a also my tentative :

I'm modifying bits of a OpenGL_accelerate.vbo.VBO object at different moments, and I'd like to print the actual whole content this object (for debug purpose).

A simple print(my_vbo) doesn't work (it prints )

Is there a simple way to get it with PyOpenGL (or must I maintain a numpy copy of the data) ?

I'm fairly new to OpenGL and I tried recreating the tutorial from https://learnopengl.com/Getting-started/Hello-Triangle to draw a rectangle in PyOpenGL.

(Original source code: https://learnopengl.com/code_viewer_gh.php?code=src/1.getting_started/2.2.hello_triangle_indexed/hello_triangle_indexed.cpp)

The first part of the tutorial that only draws a triangle using glDrawArrays works perfectly but when I try to use glDrawElements nothing is drawn. It doesn't even raise an error, it just shows me a black screen. I'm pretty sure I copied the instructions from the tutorial one by one and since there is no error message, I have no idea what I did wrong.

I would appreciate any sort of help.

My code:

I want to create a guizmo system on the pyopengl project im working in

To do that i need a way to get what object in the schene the mouse is over, is there a way to find this out?

if it helps as a example this is the project im working on https://github.com/Thiago099/Experimental-3d-modeling/blob/master/main.ipynb

i've found a program that you can move around the camera with the mouse in pyopengl, by doing some things i dont fully undesthand

I am trying to use PyQt5 to show two widgets, the first one is a plot of sin, cos and tan function. I am using the pyqtgraph and used the code that was found in the answer of this question. I am also using another widget that draws a cube using PyOpenGL, by taking the example found in this link. I am trying to show this two widgets in one main widget, which is the main window. My approach is the following

1. Take a main widget.
2. In the main widget, use a QVBoxLayout()
3. In the QVBoxLayout, at two widgets mentioned above

But when I am running the code, only the plot that is using the pyqtgraph is shown but not the cube that is drawn using PyOpenGL. After a little bit debugging, I was able to find out that the height of the cube widget is setting to 0 by default. I am not sure why this is hapenning. I tried calling glWidget.resize(640,480). But it didn't work. I am new on working with PyQt and PyOpenGL. I think I am missing some details that will allow the height of the glWidget to be greater than 0, if my assumption is correct. Also I am not sure if this is actually possible to do. My current code is given below, it is a little bit messy.
