mesh-lib

Requirements

• Linux environment
• C++23 (via g++)
• Make

Installation

1. Clone the repository:

   git clone <repository-url>
   cd mesh-lib

2. Build the project:

   make

Usage

1. Store any obj files you want to test in data/input/.

2. Time the parsers:

   bash scripts/timeit.sh

3. Graph the results:

   python3 scripts/graphit.py

The resulting data and graphs will then be stored in data/time/raw and data/time/graphs/ respectively.

Comparison with other parsers

TODO: Fill out zoo specifications (file size exceeded my laptop's memory limit)

Because testing like this is non-deterministic, the following results are approximations that try to reduce noise by "warming up" memory by doing a few parse rounds before starting the tests, averaging 20+ runs per test, and rejecting outliers via median absolute deviation. All parsers were tested on files created with the tool in scripts/generateObj.py and yielded the following results:
