Damit kann man GPX-Tracks in Videos umwandeln. Ja, das klingt ein bisschen wie HDMI auf Gardena Wasserschlauch, ergibt aber tatsächlich Sinn, siehe unten.

Das Ding spuckt bis zu 4k Video aus! Keine Registrierung nötig. Kostenlos.

OpenSCAD is software for creating solid 3D CAD models. It is free software and available for Linux/UNIX, Windows and Mac OS X. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.
