NeoTrie VR is a new software package of Virtual Reality which is currently being developed by Virtual Dor and the University of Almería, that enables users to create, manipulate, and interact with 3D geometrical objects and 3D models in general, of several types. 


The objectives of this software project are the following:

  • To examine aspects of plane geometry visible through the eyes of a third dimension.
  • To introduce 3D geometry and modelling meant for 3D printing.
  • To develop handicrafts and 3D visual skills.
  • To stimulate deductive and inductive reasoning skills.
  • To highlight cooperative work and positive interdependence.
  • To motivate pupils by means of recreational, collaborative and competitive games.


We plan to implement gaming activities and lesson plans for distinct ages and levels, covering the following subjects:

  • 2D geometry: parallels and perpendiculars, measures of lengths and angles, etc.
  • Projections of 3D figures using interactive light bulbs.
  • Construction of polyhedra (Platonics, pyramids, prisms, antiprisms, Archimedean, Johnson, Kepler, etc.).
  • Basic operations of polyhedra: duality, truncation, rectification, extension,....
  • Curved bodies (sphere, cone, cylinder, torus, etc.) by movements in space.
  • Parametrized curves and surfaces.
  • Metric calculations on 3D figures: angles, lengths, areas, volumes, Euler characteristics, etc.
  • Spatial symmetries of 3D figures.
  • Homotheties, traslations, rotations, etc.
  • Geometric 3D fractals, such as the Sierpinski tetrahedron or the Menger sponge.
  • Generation of crystalline networks from fundamental cells.
  • Euler 3D graphs (Seven Königsberg bridges problem).
  • Hamiltonian graphs (Salesman’s problem).
  • Coloring graphs (based on Four colours theorem).
  • Others (suggestions are welcome, be part of our advising team).

Featured tools:

  • Galleries of hundreds of pre-designed geometric figures.
  • Speech Recognition System to insert figures in the scenario.
  • File system to load and save scenes created by users. 
  • Multiplayer tool that enables users to create, play and learn together in the same scene (alpha version).
  • Photo camera and video recording inside the VR scene.
  • Lesson recording system for educational purposes.
  • Exporting-importing from other known programs of 3D geometry.
  • 3D printing from STL files made by NeoTrie (alpha version).
  • Multiplatform: Available for VR headsets HTC Vive, Oculus Rift (others in process Windows Mixed Reality Platform, Google Cardboard,...).
