Question 1

How do I install and use this computational geometry library in Unity?

Accepted Answer

Drag the provided folder into your Unity project, but be prepared to normalize input coordinates to 0-1 range using the included Normalizer object to avoid floating-point issues, as noted in the README. Test scenes are included for guidance.

Question 2

What's the performance like for real-time game geometry?

Accepted Answer

Performance varies by algorithm; some like Jarvis March are slower but robust, while others might have overhead. It's best for prototyping or educational use, and you may need to optimize for heavy real-time loads in complex scenes.

Question 3

Computational geometry Unity library vs Unity's built-in collision detection: which is better?

Accepted Answer

This library offers custom, fine-grained control for specific geometric calculations beyond Unity's physics, like precise polygon intersections, but Unity's built-in systems are more optimized for general-purpose collision and physics simulation.

Question 4

How can I fix the floating-point precision errors with point-in-polygon?

Accepted Answer

The README suggests normalizing all input coordinates to 0-1 range using the Normalizer object. If issues persist, consider using alternative algorithms or adjusting tolerance values, though this isn't fully documented.

Question 5

Is this library good for procedural terrain generation in Unity?

Accepted Answer

Yes, it includes tools like Voronoi diagrams and mesh generation, but be aware of limitations like incomplete Marching cubes in the TODO list, which might affect advanced terrain features.

Question 6

Can I use it for 2D games, or is it only for 3D?

Accepted Answer

It supports both 2D and 3D, with algorithms like 2D intersections and polygon clipping, but some features are 3D-focused, so check the specific implementations for your needs.
