The interactive geometry and calculus application created by Roland Mechling. Former shareware, but now open source!
Since DynaGeo is written in Delphi, this project needs the Delphi IDE from Embarcadero to be compiled. Fortunately, they offer a free Community Edition for non-commercial use.
Besides the Delphi IDE, DynaGeo needs the ZipForge component to be installed. Therefore, after installing Delphi, download the version of ZipForge that matches the IDE's Delphi version and install it.
After installing both tools, launch Delphi Community Edition and locate the DynaGeo.dproj-File in the cloned repository's root directory.
Choose either Run->Run or Run->Run Without Debugging to compile and start DynaGeo.
Have fun! :)
Contributions to DynaGeo are highly welcome, whether in programming, UI design, documentation, or dissemination!
