A modern OpenSees renderer

sees

A modern OpenSees renderer

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):

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

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

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 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 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:

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

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

python -m sees model.json --view elev

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

To see the help page run

python -m sees --help
