OTOY was the first company to demonstrate real time [[light field capture]] for [[Virtual Reality]].<ref>https://www.youtube.com/watch?v=pyJUg-ja0cg</ref> Its light field sampler system rotates 2 cameras with Canon 8-16 lens around two axis in a circle to capture the light field data of the entire spherical area around it. The data is processed and rendered with OTOY's technology to create a virtual environment that can be explored by an user of head-tracking [[HMD]]. The technology can be used to create real time, live action [[VR]].
