Project Structure

OpenGlider is organised as a set of Python packages:

Main openglider subpackages

  • airfoil — 2D/3D airfoil handling: normalise, resample, conformal mapping, parametric profiles. Profiles follow the .dat convention (see Concepts).

  • glider — Core glider data: * Glider, Cell, Rib (and miniribs), ballooning, shape. * ParametricGlider — 2D/parametric design (ODS import/export, shape, arc). * in_out — import/export 3D geometry and spreadsheet data.

  • lines — LineSet, lines, and nodes. Line geometry is computed as a linear system; sag can be added. Used for paragliders, kites, etc.

  • mesh — Triangulated 3D mesh from a Glider (and optional lines). Export to OBJ, DXF, etc.

  • plots — Cutting patterns, DXF export, spreadsheets (material lists, straps, rigidfoils), and sketches (line plan, shape plot).

  • vector — 2D/3D vector maths, polylines, polygons, splines (Bezier, B-spline), projection, drawing layout.

  • graphics — VTK-based visualisation (polygons, points) for quick 3D inspection.

  • jsonify — Serialise/deserialise OpenGlider objects to JSON and migrate between schema versions.

  • utils — Helpers: cache (cached properties), distribution, colors, table, etc.

Glider and Airfoil (short reference)

A Glider is made of Cells; each cell is defined by two Ribs (and optional miniribs). Ballooning is defined per rib. The LineSet attaches to the canopy. See Concepts.

Airfoils are lists of (x, y) points from upper trailing edge via nose to lower trailing edge. You can query points by normalised x in (-1, 1). See Concepts.
