The following code creates the 3D colored cube, which follows the code. This time, we will use the keyboard arrow keys to rotate the image instead of the mouse:

import pyglet 
from pyglet.gl import * 
from pyglet.window import key 
from OpenGL.GLUT import * 

WINDOW    = 400 
INCREMENT = 5 

class Window(pyglet.window.Window): 

    # Cube 3D start rotation 
    xRotation = yRotation = 30     

    def __init__(self, width, height, title=''): 
        super(Window, self).__init__(width, height, title) 
        glClearColor(0, 0, 0, 1) 
        glEnable(GL_DEPTH_TEST)     

    def on_draw(self): 
        # Clear the current GL Window 
        self.clear() 

        # Push Matrix onto stack 
        glPushMatrix() 

        glRotatef(self.xRotation, 1, 0, 0) 
        glRotatef(self.yRotation, 0, 1, 0) 

        # Draw the six sides of the cube 
        glBegin(GL_QUADS) 

        # White 
        glColor3ub(255, 255, 255) 
        glVertex3f(50,50,50) 

        # Yellow 
        glColor3ub(255, 255, 0) 
        glVertex3f(50,-50,50) 

        # Red 
        glColor3ub(255, 0, 0) 
        glVertex3f(-50,-50,50) 
        glVertex3f(-50,50,50) 

        # Blue 
        glColor3f(0, 0, 1) 
        glVertex3f(-50,50,-50) 

        # <... more color defines for cube faces> 

        glEnd() 

        # Pop Matrix off stack 
        glPopMatrix() 

    def on_resize(self, width, height): 
        # set the Viewport 
        glViewport(0, 0, width, height) 

        # using Projection mode 
        glMatrixMode(GL_PROJECTION) 
        glLoadIdentity() 

        aspectRatio = width / height 
        gluPerspective(35, aspectRatio, 1, 1000) 

        glMatrixMode(GL_MODELVIEW) 
        glLoadIdentity() 
        glTranslatef(0, 0, -400) 

    def on_text_motion(self, motion):  
        if motion == key.UP: 
            self.xRotation -= INCREMENT 
        elif motion == key.DOWN: 
            self.xRotation += INCREMENT 
        elif motion == key.LEFT: 
            self.yRotation -= INCREMENT 
        elif motion == key.RIGHT: 
            self.yRotation += INCREMENT

    Window(WINDOW, WINDOW, 'Pyglet Colored Cube') 
    pyglet.app.run()

Using the keyboard arrow keys, we can spin the 3D cube around:
