In fact, the virtual reality technology comes from the sci-fi plot imagined by the novelist, and finally becomes the real technology. The term Virtual Reality first appeared in the less than 40-page novel "Pygmalion's spectacles" by American science fiction writer Stanley Winbaum in 1935, describing that the protagonist can wear glasses. Immerse yourself in a movie that simulates sight, hearing, taste, smell and touch.
However, even after more than 80 years, the current VR technology is still based on glasses (including visual and auditory), with auxiliary tools to provide tactile feedback or control.
The birth of the ray tracing GPU means that the breakthrough of VR software simulation technology can be closer to the real world image quality, but the progress of software alone is not enough. VR equipment is another key to realize the VR world.
As early as 1838, almost 100 years before the publication of the novel, products using stereoscopic simulation technology have already appeared. In recent years, it has developed into more types of virtual reality glasses, and even various types of VR glasses such as hybrid reality, near-eye projection, and super wide field of view. VR imaging software technology, coupled with the maturity and commercialization of VR hardware devices, enabled this sci-fi technology to be realized. This year's SIGGRAPH conference also set up a retrospective exhibition of VR glasses to showcase the key VR hardware products over the years to present the progress and breakthrough of VR technology.
