- TITLE: Using Pysketcher to Create Principal Sketches of Physics Problems
- AUTHOR: Hans Petter Langtangen at Center for Biomedical Computing, Simula Research Laboratory & Department of Informatics, University of Oslo

- __Abstract.__
- Pysketcher is a Python package which allows principal sketches of
- physics and mechanics problems to be realized through short programs
- instead of interactive (and potentially tedious and inaccurate)
- drawing. Elements of the sketch, such as lines, circles, angles,
- forces, coordinate systems, etc., are realized as objects and
- collected in hierarchical structures. Parts of the hierarchical
- structures can easily change line styles and colors, or be copied,
- scaled, translated, and rotated. These features make it
- straightforward to move parts of the sketch to create animation,
- usually in accordance with the physics of the underlying problem.
- Exact dimensioning of the elements in the sketch is trivial to obtain
- since distances are specified in computer code.
- Pysketcher is easy to learn from a number of examples. Beyond
- essential Python programming and a knowledge about mechanics problems,
- no further background is required.
- # Task (can be questions): make sketches of physical problems, see fig
- # through user-friendly composition of basic shapes
- # Desired knowledge: plotting curves, basic OO (ch. X.Y, ...)
- # Required knowledge?
- # Learning Goals: these targets the inner workings of pysketcher,
- # which is just a part of this document...
