What are the differences between popular physics engines?

There are several popular physics engines like Unity's PhysX, Bullet, and Havok. Each has its strengths. For instance, PhysX is great for real-time simulations, while Bullet is open-source and widely used in games.

Can you explain how Unity's PhysX works?

Unity's PhysX engine simulates real-world physics by using rigid body dynamics, allowing for realistic interactions between objects. It handles collisions, gravity, and other forces.

What are the advantages of using Bullet over PhysX?

Bullet is open-source, which makes it highly customizable. It's also known for its performance in complex simulations and is widely used in both games and simulations.

Are there any limitations to using Havok?

Havok is powerful but can be expensive for smaller developers. It also has a steeper learning curve compared to some other engines.

Which physics engine would you recommend for a beginner?

For beginners, I recommend starting with Unity's PhysX due to its extensive documentation and community support, making it easier to learn.
