`sees` is a finite element rendering library that leverages modern 
web technologies to produce sharable, efficient, and beautiful renderings.

Documentation is currently under development.

## Features

- Extruded deformed shape

- Detailed section rendering

- A wide selection of rendering backends and output file types, including 
  optimized 3D web formats like `.glb`.

- Correctly render models that treat both `y` or `z` as the
  vertical coordinate.

-------------------------------------------------------------------- 

## Command Line Interface

To create a rendering, execute the following command from the anaconda prompt (after activating the appropriate environment):

```shell
python -m sees model.json -o model.html
```

where `model.json` is a JSON file generate from executing the following OpenSees command:

```tcl
print -JSON model.json
```

If you omit the `-o <file.html>` portion, it will plot immediately in a new
window. You can also use a `.png` extension to save a static image file, as
opposed to the interactive html.

> **Note** Printing depends on the JSON output of a model. Several materials and
> elements in the OpenSeesPy and upstream OpenSees implementations do not
> correctly print to JSON. For the most reliable results, use the
> [`opensees`](https://pypi.org/project/opensees) package.

By default, the rendering treats the $y$ coordinate as vertical.
In order to manually control this behavior, just pass the  option 
`--vert 3` to render model $z$ vertically, or `--vert 2` to render model $y$ vertically.

If the [`opensees`](https://pypi.org/project/opensees) package is installed,
you can directly render a Tcl script without first printing to JSON, 
by just passing a Tcl script instead of the JSON file:

```shell
python -m sees model.tcl -o model.html
```

To plot an elevation (`elev`) plan (`plan`) or section (`sect`) view, run:

```shell
python -m sees model.json --view elev
```

and add `-o <file.extension>` as appropriate.

To see the help page run

```shell
python -m sees --help
```
