# Obj2Html
This lib is able to transform an .obj file to HTML that use three.js.
In this way it is possible to have an interactive 3D view that can be used on the browser or into a jupyter notebook.

Install with `pip install obj2html` and use with `obj2html('model.obj', 'index.html')`

![](imgs/colab_sample.png)

* run into [jupyter notebook](https://jupyter.org/) ([jupyter_example.ipynb](examples/jupyter_example.ipynb)):
```
! pip install obj2html
! wget https://gitlab.com/nicolalandro/obj2html/-/raw/main/test/assets/model.obj
from obj2html import obj2html
from IPython.display import display, HTML

obj2html('model.obj', 'index.html')

display(HTML('index.html'))
```
* run into [streamlit](https://streamlit.io/) app ([streamlit_example.py](examples/streamlit_example.py)):
```
# pip install obj2html streamlit
# have a model.obj (wget https://gitlab.com/nicolalandro/obj2html/-/raw/main/test/assets/model.obj)

import streamlit as st
import streamlit.components.v1 as components
from obj2html import obj2html

html_string = obj2html("model.obj", html_elements_only=True)
components.html(html_string)
with open("model.obj") as f:
    st.download_button('Download model.obj', f, file_name="download_name.obj")
```

# Dev

* run test
```
python3.8 -m unittest discover
```
* run test with coverage
```
pip install coverage
python3.8 -m coverage run --source=src -m unittest discover
python3.8 -m coverage report -m
```
* deploy pipy
```
pip install twine

rm -rf dist

python setup.py sdist
twine check dist/*

twine upload dist/*
