MarsCycler3D is a completed 3D app for Nasa Space App challenge based on babylonjs
App shows Earth-Mars travel. Can be used as a presentation or flight simulator (with cabin view). Paths were calculated by astrophysicist Maxim Quartly from Queen Mary University of London. You can see a path and a time of the travel, and it is good for education using (schools, colledges, etc). Supports VR mode.
