While working on the National Geographic Special “Sunken Treasures of the Nile” we were very interested in how we could represent the terrain of the surrounding area. Unfortunately there were no DEM (Digital Elevation Models) of this remote area and we were unable to charter an aircraft due to the designation of military air-space. The only method we had available to us for re-creating this kind of terrain was through the use of Kite Aerial Photography and Photogrammetry. We were able to capture 57 million 3D points of the terrain from this simple aerial platform and a DSLR.
One innovative technique developed at xRez Studio is the integration of digital elevation models (DEM) with high-end 3d rendering and gigapixel images. Another innovation we have developed is to integrate time lapse sequences with DEM data, allowing new, inventive cinematography where a virtual camera can dolly deeply into the image while lapsing in time.
