The document discusses the emerging technology of 3D internet. It begins by defining 3D internet as the combination of the internet and 3D graphics delivered in real-time over the web. Previously, 3D content was difficult to access due to slow computers and internet connections. However, increased bandwidth and processor speeds now allow high-quality 3D graphics to be interacted with online. Examples are given of potential applications in education, commerce, entertainment and collaboration. While 3D worlds were initially complex and expensive, the future of 3D internet is promising as it will make controlling information and interacting online much more intuitive.
