QUEST3D 5.0 VR EDITION FOR FREE

In October 2009, the former Indie-version of Unity was made available for free which resulted in another large increase in users. After releasing a Windows-based version of the previously Mac-only engine in March 2009, Unity has seen a steady rise in its userbase. Unity's game engine has been through tremendous changes since early 2009. On the contrary, the user community and forum have always been helpful and quick to answer questions. However, the documentation of the latest release (Quest3D 4.x) appears to be inferior to other development engines, especially regarding the use of object-oriented development. Custom logic can be integrated via the LUA scripting language and custom channels can be created via C++. Quest3D features a visual scripting approach supports development without any programming knowledge via node-based systems of logic blocks/channels. Vizard has the advantage of using Phyton, a well-documented programming and scripting language for which there are many books and tutorials available. An active user-community, thorough documentation and the availability of online tutorials are of particular value for this requirement.

Main requirement for choosing a development platform is the easy entry to developing and publishing interactive VEs. An overview of each application and how each addresses this thesis’ requirements can be found in Table 2. Their feature sets, target audience and business model did not seem appropriate for the purpose of this thesis. Additional programs such as UDK 19 and Torque3D 20 have also been evaluated, but have not been used more extensively. Information about each application was collected through user forums, documentation, tutorials and conversations with existing users. Based on subjective judgment, expected project tasks, and experiences gained from the development of the initial prototypes, a list of requirements was derived in order to select a game engine for this project. These prototypes were mostly unrelated to this thesis and will not be discussed in detail. Small prototypes were developed which included importing 3D models, implementing user input and data recording ( Figure 1).
