Description

Particle simulation is used quite often in computer graphics to generate the motion. Today you will be simulating mass particles to generate an animation for lava. In contrast to previous labs, the animations you generate today will be created almost automatically through integration of Newton's Second Law of Motion, f=ma. This lab will demonstrate the power of particle simulation for animating complex phenomenon.

You should implement the particle system discussed in the provided PDF. You will need to implement the following components:

• The particle struct containing all the necessary information
• The Euler integrator
• Ground contact and friction
• The material of the particles

It should appear similar to the image below. Make sure you introduce some randomness into the initial velocity of particle, otherwise your lava will look eerily uniform and un-compelling. Your crater should also emit particles indefinitely.

Optional

Make the lava more realistic by introducing other sources of force. Some examples are:

• Explosive forces at the base to make the lava more volatile and unpredictable
• Wind vortices
• Viscous forces between neighboring particles
