NMesh is a Python package that provides two high-level features:

• A simple Mesh processor
• A list of tool to convert mesh files into point cloud

You can reuse your favorite Python packages such as NumPy, SciPy and Cython to extend ZakuroCache integration.

Modules

At a granular level, NMesh is a library that consists of the following components:

Component	Description
nmesh	Contains the implementation of NMesh
nmesh.core	Contain the functions executed by the library.
nmesh.cp	Processor for the point cloud

Code design

• We recommend using Docker for dev and production. Therefore we encourage its usage all other the repo.
• We have vanilla and sandbox environment.
  • Vanilla refers to a prebuilt docker image that already contains system dependencies.
  • Sandbox referes a predbuilt docker image that contains the code of this repo.
• Semantic versioning https://semver.org/ . We commit fix to a.b.x, features to a.x.c and stable release (master) to x.b.c.
• PR are done to dev and reviewed for additional features. This should only be reviewed by the engineers in the team.
• PR are done to master for official (internal) release of the codes. This should be reviewed by the maximum number of engineers.
• The ETL jobs are scatter accross sequential refinement of the data landing/bronze/silver/gold
• Modules and scripts: Any piece of code that can of use for parent module modules should be moved at a higher level.
  • eg: functional.py contains common funtions for etl.bronze and etl.silver

...
├── etl
│   ├── bronze
│   │   ├── __init__.py
│   │   └── __main__.py
│   ├── functional.py
│   ├── __init__.py
│   └── landing
│       ├── __init__.py
│       └── __main__.py
├── functional.py
├── __init__.py
...

• Modules should ideally contain a __main__.py that demo an exeution of the module
  • etl/bronze/__main__.py describes an etl job for the creation of the bronze parition
  • trainer/__main__.py describes the training pipeline
