| summary |
We use digitally made spherical panoramas as background for vr visualisation in architectural sceneries instead of stitched photographs (fisheye-based or serical-mirror-based). For this reason we had the idea to develop the first fisheye-based digitalscanning panorama-camera together with the manufacturer Spheron. The ultimate step in reaching optimal quality not only as a background but also as a source of lighting the background-image is taken as a HDR-image. The high-dynamic-range-technology was developed by the Californian scientist Paul Devebec. High dynamic photographs contain a broader range of information between the very bright zones down to the very dark zones - a lot more than “normal” photographs (digital and analogue), which are named LDR (low dynamic range in comparison to HDR). Some software-products in the field of cad-visualisation in virtual and augmented reality already enable the use of HDR-images and open a new field of controlling daylight and artificial light simulations with photographed backgrounds instaed of synthetic ones. The combination of digitally produced (scanned) spericalimages together with the use of HDR open a wide range of new implementation in the field of architecture, especially in combining synthetic elements in existing buildings, e.g. new interior elements in an existing historical museum). |
