Oar 3D is an effective tool to create and to modify models 3D destined to the visualization in real time. Main file format Oar 3D is OpenFlight ®, but that allows to import and to export to different file formats. Unlike many other products of modeled 3D that are destined mainly for the representation, Oar 3D offers to the user a total control of the graphical scene of the model and allows the modification of characteristics like the degree of nodes of the freedom, the level of detail nodes, the nodes of change, etc In addition, the process to create models in 3D allows Oar to concentrate in the individual polygons and vertices. Altogether, this does that exceptionally appropriate Oar 3D to create and to modify models 3D destined to the visualization in real time.
