Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for new users

   Bullet3's API is complex and requires a deep understanding of physics concepts and C++ programming.

2. 02

   Limited language support beyond C++

   While Bullet3 primarily supports C++, bindings for other languages like Python are community-maintained and may not be as robust or up-to-date.

3. 03

   Performance issues with large-scale simulations

   Complex scenes with a high number of objects can lead to significant performance degradation, making it less suitable for very large-scale applications without optimizations.

4. 04

   Documentation is extensive but not always clear or beginner-friendly

   The documentation covers many aspects but assumes prior knowledge and may be difficult to navigate for newcomers.
