1) Market penetration is reaching a critical mass. 3D enabled devices now dominate the market and are poised to become a standard feature of home entertainment. 2) The cost of buying 3D enabled devices has gone down. TVs, playback devices (game consoles, dvr devices, etc), and cameras are more affordable than ever. 3) 3D Tech is now making strides into mobile devices with Nintendo, Google, and Motorola notably making devices and content for 3D mobile. 4) The tech offers solutions to art forms that heretofor were previously poorly served by older 2D imaging technology (aka dance and opera)
1) 3D on film has been linked to nausea and headaches and even in video there have been questions about eye strain although these problems only seem to afflict a small portion of audience members. Evidently the trick is to not focus on out of focus images on the screen if you suffer from these problems. 2) It will be a couple more years before the majority of TV’s and Mobile devices can run 3D content. As with any technology there is only a point to which it will grow as people are reluctant to buy a 3D enabled HD TV (or playback device) a year after they shelled out for a new HD TV set. 3) There is the possibility that another breakthrough will be made in imaging that will make current imaging technology obsolete. For now, however, the long-term outlook seems to be favoring the current technology’s dominance for the next 6-8 years. 4) You still need those pesky glasses (for now at least).
One could argue that 3D still has a ways to go. The cutting edge of the field however offers the potential for much much more spectacular devices. Now that it is becoming fiscally accessible some artists and organizations have waded in and started experimenting but the potential remains largely untapped. Whatever happens, it will pay to keep a watch on this technology
