Mathematics is "a world of variables" of nature that lies between philosophy and reality. Teaching mathematics has always been an intriguing task, especially in areas of mathematics where visualization is overcome by conceptualism. In such cases, it is vital for the learner to understand the effects of each concept and its application to the real world. Thus, an educational platform aiming at mathematics education should, besides offering an intriguing environment, where easily visualized concepts may be applied, be capable of producing the results of less perceptual models to the user. An approach in this area would be utilizing 3D technologies, in order to provide an intriguing environment for the learner to acquire mathematical experience through problem solving imposed by the system. Instead of utilizing 3D representation of mathematical concepts, our approach utilizes 3D technologies as the basis for the user to get acquainted with mathematical problem solving and gradually build up knowledge through solving itself. In this scope, we have developed a VR educational platform for mathematics named Educational Virtual Environment - Mathematics (EViE-m). EViE-m platform offers an environment where the user tries to construct an organized city through answering to simple or complex mathematical questions that offer the possibility of gaining access to buildings and technology trees. The greater the level the user has reached, the more advanced the questions they have to answer in order to evolve their city. Thus, this imposes certain technological requirements that need to be dealt with in developing such approaches. These requirements stem also from the capabilities of the platform in the areas of networking, scenarios (problem solving) and random event generation - all the unique modules that provide user interaction and motivating user environment. In this paper we present the technological requirements - and potential solutions - imposed by the technologies engaged in our approach, as X3D technology, as well as the architectural procedures we have identified in the development of EViE-m.
