Volumetric photogrammetry — big words, bigger impact on VR

Virtual reality: By this point, most people have at least a rudimentary understanding of what the term means. Once enjoyed and developed for niche techie and gaming audiences, brands have quickly realized VR’s limitless potential, and, as a result, every interest group from interior design to makeup to apparel is jumping on the immersive content bandwagon.

For consumers, VR generally means strapping on a head-mounted display (HMD), stepping into a new world and enjoying the experience. The enveloping nature of VR allows people to explore environments in 360 degrees, but for most, how these immersive worlds are created is a mystery.

Though VR is still in its infancy, “traditional” methods of capturing and transforming footage have emerged. Typically, to shoot 360-degree VR content, a cameraperson employs several cameras rigged in a spherical formation to capture the scene. According to Alicia Millane’s blog entry on The Primacy, “Each camera is mounted at a specific angle so the camera’s field of view will overlap portions of the surrounding cameras’ field of view.” With the overlap, editors should be able to get more seamless footage, without any gaps. Alternatively, professional 360-degree cameras can be purchased, but more or less look and function the same as hand-rigged apparatuses. Once filming is completed, editors stitch together the footage, creating a unified, continuous experience.
