BRAIN. Broad Research in Artificial Intelligence and Neuroscience-Prototyping 3D Virtual Learning Environments with X3D-based Content and Visualization Tools

Over the last decade, learning settings on SecondLife or OpenSimulator 3D online platforms
are employed as a distance service by virtualizing educational spaces or even an entire university
campus. To immerse and engage the learners in a 3D space, architectural and ambient objects need
to be designed, besides the transfer of the educational assets in a 3D/2.5D environment. The present
research addresses the existing limitations of the current 3D online platforms in terms of content
creation, management and interoperability. Several open 3D and web-based technologies, e.g. X3D
or WegGL, are investigated and evaluated for their possible use for complex 3D and non-3D content
in online environments. A working methodology and recommendation of tools are proposed for a
more productive development and a prototyping pipeline. The tools provide a higher level of
interactivity and facilitate the content visualization in browsers and mobile devices.
