OpenSpace3D is a free and Open Source development platform for interactive real time 3D projects. Its mains advantages are: User friendly, you can create a whole interactive 3D scene, with great graphical quality, without writing any code. Power, lots of functionality are directly included, realizing an OpenSpace3D application consist in linking functionalities together, and defining theirs mutual interactions. Technological advance, our team keep searching for and integrates the last technologies in domains of virtual reality, speech recognition, and computer graphics. It's goals: Facilitate the development of new collaborative work environments (distant meetings in web conference), training (virtual classroom, learning and serious games), simulation, innovation, e-commerce (shopping malls and virtual shops), social networks of expression and sharing (personal 3D spaces) or massively multiuser games (MMOG) both professional and public applications. Provide engineers and developers an open and free development platform for real-time 3D application and allow them to prototype new Virtual Reality HMI. Democratize the use of 3D real-time and allowing access to a wide audience ranging from students to large accounts through SMEs and research institutions.
