a script helps to export svg for Geogebra 3d calculator.
44
[Geogebra 3d calculator](https://www.geogebra.org/3d) is an excellent app for 3d graph. But we cannot export the final result to svg file. This script can parse the project file (.ggb) and convert to a set of Geogebra commands which you can load to [Geogebra geometry](https://www.geogebra.org/geometry), then you can export to svg file from Geogebra geometry.

# Environment setup
7+
You can use anaconda to setup environment.
8+
```
9+
conda create -n Your_environment_name python=Your_Python_Version
10+
conda activate Your_environment_name
11+
conda install -c anaconda numpy -y
12+
conda install -c conda-forge shapely -y
13+
```
14+
Or you can simply do like this:
15+
```
16+
conda env create -f environment.yml
17+
conda activate Geogebra
18+
```

# Usage

```python
822
python ./GeoGebra3dTo2D.py --dataLocation=./data/OGLCoor_zn.ggb

```

The script will create a folder with your file name (OGLCoor_zn in example) and you can see "commandList.txt" under that folder. Copy the content of "commandList.txt" and paste to [Geogebra geometry](https://www.geogebra.org/geometry).
25+
./data/OGLCoor_zn.ggb and ./data/commandList.txt are provided for test.

# Limitation

- I only support "Segment", "Vector", "Polygon" in the graph, will add "Ray", "Line" soon.
28+
- I only support "Segment", "Vector", "Polygon" and "Point" in the graph, will add "Ray", "Line" later.
1429
- Text command from Geogebra failed to support Latex format, so the script didn't create related text to Geogebra geometry. But you can manually create them.
