caption_attribution_description: English: This Leica terrestrial lidar (light detection and ranging) scanner (TLS) may be used to scan buildings, rock formations, etc., to produce a 3D model. The TLS can aim its laser beam in a wide range: its head rotates horizontally, a miror flips vertically. The laser beam is used to measure the distance to the first object on its path. Model: Leica HDS-3000 The Lidar was being demonstrated at UC Santa Cruz when the photo was taken.
context_page_description: Volumetric video is a technique that captures a three-dimensional space, such as a location or performance. This type of volumography acquires data that can be viewed on flat screens as well as using 3D displays and VR goggles. Consumer-facing formats are numerous and the required motion capture techniques lean on computer graphics, photogrammetry, and other computation-based methods. The viewer generally experiences the result in a real-time engine and has direct input in exploring the generated volume.
context_section_description: LIDAR scanning describes a survey method that uses laser-sampled points densely packed to scan static objects into a point cloud. This requires physical scanners and produces enormous amounts of data. In 2007 the band Radiohead used it extensively to create a music video for "House of Cards", capturing point cloud performances of the singer's face and of select environments in one of the first uses of this technology for volumetric capture. Director James Frost collaborated with media artist Aaron Koblin to capture 3D point-clouds used for this music clip, and while the final output of this work was still a rendered flat representation of the data, the capture and mindset of the authors was already ahead of its time. Point clouds, being distinct samples of three-dimensional space with position and color, create a high fidelity representation of the real world with a huge amount of data. However, viewing this data in real-time was not yet possible.
