# pst-vehicle: creating vehicles for physical animations This package was created to illustrate the notion of slope, the coefficient of the tangent line at a point of a curve. On the road, a rampant way or a dangerous descent due to their slope is indicated by a sign showing the percentage of the slope of this section of road, for example 10%. It was therefore quite obvious that the idea of representing a vehicle rolling without slipping on a curve came into our minds. Different types of vehicles are proposed, the shape of the curve is to be defined by its equation: $y=f(x)$ in algebraic notation. Save the files pst-vehicle.sty|data|tex in a directory, which is part of your local TeX tree. The pro file should go into $TEXMF/dvips/pstricks/ Then do not forget to run texhash to update this tree. pst-vehicle needs pstricks, which should be part of your local TeX installation, otherwise get it from a CTAN server, https://mirror.ctan.org PSTricks is PostScript Tricks, the documentation cannot be run with pdftex, use the sequence latex->dvips->ps2pdf or pdflatex with package auto-pst-pdf or xelatex or (best) lualatex This program can redistributed and/or modified under %% the terms of the LaTeX Project Public License %% Distributed from CTAN archives in directory %% macros/latex/base/lppl.txt; either version 1.3c of %% the License, or (at your option) any later version. %% Thomas Söll Bugs: hvoss@tug.org %% $Id: README.md 819 2018-09-26 06:40:48Z herbert $
