How can I simulate 3D graphics and collisions using VPython?

You can use VPython to create 3D objects and define their properties. To simulate collisions, you can check for overlaps between objects and respond accordingly.

Can you show me a simple example of a collision between two spheres?

Sure! Here's a basic example:

from vpython import *

# Create two spheres
sphere1 = sphere(pos=vector(-1,0,0), radius=0.5, color=color.red)
sphere2 = sphere(pos=vector(1,0,0), radius=0.5, color=color.blue)

# Animation loop
while True:
    rate(50)  # Limit the loop to 50 iterations per second
    sphere1.pos.x += 0.01  # Move sphere1 to the right
    # Check for collision
    if mag(sphere1.pos - sphere2.pos) < (sphere1.radius + sphere2.radius):
        sphere1.color = color.green  # Change color on collision

What happens if the spheres collide?

In this example, when the two spheres collide, the color of sphere1 changes to green, indicating a collision has occurred.

Can I add more objects and make them interact?

Yes, you can add more objects and define their interactions. You can implement physics rules to make them bounce off each other or respond to forces.
