simulate: A cube and a ball in virtual reality for two eyes

To simulate a cube and a ball in virtual reality for two eyes, we can use Python and the Pygame library. Here’s some example code that will create a simple 3D scene with a cube and a ball that can be viewed in virtual reality using two eyes:

makefileCopy codeimport pygame
from pygame.locals import *

# Define some colors
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)

# Initialize Pygame
pygame.init()

# Set the display size
display_size = (640, 480)

# Create the display
screen = pygame.display.set_mode(display_size)

# Set the eye separation distance
eye_sep = 0.1

# Set up the camera position
camera_pos = (0, 0, 2)

# Set up the cube and ball positions
cube_pos = (-1, 0, 0)
ball_pos = (1, 0, 0)

# Define the cube vertices and edges
cube_verts = [
    (1, 1, 1),
    (1, 1, -1),
    (1, -1, 1),
    (1, -1, -1),
    (-1, 1, 1),
    (-1, 1, -1),
    (-1, -1, 1),
    (-1, -1, -1),
]

cube_edges = [
    (0, 1),
    (0, 2),
    (0, 4),
    (1, 3),
    (1, 5),
    (2, 3),
    (2, 6),
    (3, 7),
    (4, 5),
    (4, 6),
    (5, 7),
    (6, 7),
]

# Define the ball radius
ball_radius = 0.5

# Set up the main game loop
running = True
while running:

    # Handle Pygame events
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # Clear the screen
    screen.fill(BLACK)

    # Calculate the camera position for each eye
    left_eye_pos = (camera_pos[0] - eye_sep/2, camera_pos[1], camera_pos[2])
    right_eye_pos = (camera_pos[0] + eye_sep/2, camera_pos[1], camera_pos[2])

    # Draw the cube for each eye
    for eye_pos in [left_eye_pos, right_eye_pos]:

        # Calculate the position of the cube relative to the camera
        rel_cube_pos = (cube_pos[0] - eye_pos[0], cube_pos[1] - eye_pos[1], cube_pos[2] - eye_pos[2])

        # Calculate the vertices of the cube in screen space
        cube_verts_screen = []
        for vert in cube_verts:
            x = (eye_pos[2] * vert[0]) / (eye_pos[2] - rel_cube_pos[2])
            y = (eye_pos[2] * vert[1]) / (eye_pos[2] - rel_cube_pos[2])
            cube_verts_screen.append((int(display_size[0]/2 + x*100), int(display_size[1]/2 - y*100)))

        # Draw the edges of the cube
        for edge in cube_edges:
            pygame.draw.line(screen, RED, cube_verts_screen[edge[0]], cube_verts_screen[edge
