Abstract— Virtual reality is used in the production of complex virtual environments involving input and output nontrivial devices to allow users a sense of immersion in real time synthetic worlds. Many approaches to software development are used to promote increased productivity and reuse of elements of virtual reality applications, such as routine libraries, frameworks and component platforms. However, the most approaches provide reuse by means of source code of programs or reuse of compiled components. Aiming to increase the reuse potential of elements of virtual reality applications, this paper proposes a representation model of applications and an architectural model for a remote online software platform. The service-oriented platform supports production, reuse, sharing and execution of virtual reality applications in a remote environment and online. The goal is to produce, share and reuse elements of virtual reality applications on a higher level than that of the source code of computer programs. The results obtained with architectural model validation and the developed prototypes indicate the viability of the representation model of virtual reality applications proposed.
