RA7: Large-Scale Virtual Environments

Vision and Research Strategy

Since the original proposal, the field of graphics has changed significantly, directly affecting this research area as well: graphics hardware has become ubiquitous, now that even mobile phones contain fast graphics processors; stereo displays are used in movies and are expected to become a commodity even in private households; and fast Internet connections are much more common today. This is changing the landscape for our research dramatically; altogether, this now allows immersive and interactive graphics to be easily brought to a much wider audience than was possible before.

We have reacted to this development by integrating our base technology into Web browsers using XML3D, our new extension to HTML described briefly below and in more detail in Section. Instead of requiring specialized application, it allows us to easily make much of our technology directly available to the general public, industry, and other researchers. Furthermore, since XML3D is firmly based on Web standards and technology, we massively expand on the number of programmers that can use their existing knowledge to make use of our research and create interesting new graphics applications and business cases. XML3D is already integrated into prototypes of existing browsers, and we are actively pursuing standardization via W3C. Through its ease of use and familiarity, XML3D also provides a useful tool for many of our research activities as outlined below.

However, our main research vision and strategy from the original proposal have remained unchanged, as the challenges outlined there have not been otherwise solved. We have made considerable progress in all these research topics during the report period, as outlined below.
