A ski jump design and analysis tool for equivalent fall height based on the work presented in Levy, Dean, Mont Hubbard, James A. McNeil, and Andrew Swedberg. "A Design Rationale for Safer Terrain Park Jumps That Limit Equivalent Fall Height." Sports Engineering 18, no. 4 (December 2015): 227–39. https://doi.org/10.1007/s12283-015-0182-6. Includes a library for 2D skiing simulations and a graphical web application for designing and analyzing ski jumps. It is written in Python backed by NumPy, SciPy, SymPy, Cython, matplotlib, Pandas, Plotly, and Dash.
