How can I optimize a physics engine for better performance?

How can I optimize a physics engine for better performance?

To optimize a physics engine, consider techniques like spatial partitioning, reducing collision checks, and using simpler shapes.

What is spatial partitioning and how does it help?

Spatial partitioning divides the game world into sections, reducing the number of collision checks by only testing objects in the same section.

Are there specific algorithms for collision detection that are more efficient?

Yes, algorithms like the Bounding Volume Hierarchy (BVH) and Sweep and Prune can significantly improve collision detection efficiency.

How can I balance accuracy and performance in my physics simulations?

You can balance accuracy and performance by adjusting the timestep, using adaptive resolution, and selectively applying physics calculations.
