from OpenGL.GLU import *

# Define vertices and edges for a cube
vertices = (
    (1, -1, -1),
    (1, 1, -1),
    (-1, 1, -1),
    (-1, -1, -1),
    (1, -1, 1),

# Initialize Pygame and the OpenGL context
pygame.init()
display = (800, 600)
pygame.display.set_mode(display, DOUBLEBUF|OPENGL)

# Set perspective
gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)

# Move cube away from camera
glTranslatef(0.0,0.0, -5)

# This function will draw the edges of a cube
def Cube():
    glBegin(GL_LINES)
    for edge in edges:
        for vertex in edge:
            glVertex3fv(vertices[vertex])
    glEnd()

# Main loop
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

    # Rotate cube
    glRotatef(1, 3, 1, 1)
    
    # Clear buffers
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
    
    Cube() # Render the cube
    
    pygame.display.flip()
    pygame.time.wait(10)

Code Output:

The output of the code is a 3D rendering of a rotating cube on a window created with Pygame and OpenGL. The cube is continuously spinning due to the rotation logic applied in the main loop. The window has a display size of 800 by 600 pixels.

Code Explanation:

The code starts by importing the necessary modules from Pygame and OpenGL. These modules will enable us to create a window, render shapes, and manipulate their appearance in 3D space.

The vertices variable consists of 8 tuples, each representing the 3D coordinates of a cube’s corner. edges consist of pairs of indices into the vertices list, indicating which vertices are connected by an edge.

Next, we initialize Pygame, set up the display mode with a width and height of 800 by 600 pixels, and then enable an OpenGL double buffer. The gluPerspective function establishes a perspective projection, setting a field of view angle, the aspect ratio of the window, and the near and far clipping planes.

The glTranslatef function is used to push the cube away from the camera along the z-axis, ensuring that it is visible when rendered.

The Cube function utilizes OpenGL commands to draw the cube. It begins a series of line drawings with glBegin(GL_LINES), iterates through the edges to grab the corresponding vertices, and then uses glVertex3fv to specify each line’s endpoints before finishing with glEnd().

The main loop of the program checks for the QUIT event to allow for a clean exit. Inside this loop, glRotatef is called to apply a rotation to the entire scene for each frame, which creates the animation of the rotating cube. The glClear function clears the color and depth buffers to ready them for the next frame.

Finally, Cube() is called to draw the updated cube, pygame.display.flip swaps the buffers to show the new frame, and pygame.time.wait(10) introduces a short pause to control the speed of the rotation.

Overall, the architecture of the code is straightforward, with a set-up phase, a loop to handle real-time rendering, and an animation section that modifies object transformations to create the appearance of a spinning 3D object. The use of Pygame handles the window management and user events, while OpenGL takes care of the actual 3D rendering. Thanks for diving into the world of 3D with me! Keep spinning those cubes, folks! 🎮🔄
