..| RealReflect at Eurographics 2004 Posted by ubo on Monday, August 23 @ 12:14:26 CEST

The rationale of RealReflect and selected results will be presented at the Eurographics 2004 conference, which will be held August 30th - September 3rd in Grenoble, France. A project presentation will present the rationale, a State of the Art Report and parts of a tutorial will focus on bidirectional texture function (BTF) rendering.

    Dates and locations:

  • Tutorial (Tutorial 1): bridal shower dresses
    Monday, 30.08.2004, 8:30-17:30, Amphi EM 302
  • State of the Art Report (STAR 3):
    Tuesday, 02.09.2004, 8:30-10:00, Makalu
  • Project presentation:
    Friday, 03.09.2004, 13:30-14:00, Main Auditorium

..| RealReflect Presentation on IVR 2004 Posted by icido on Tuesday, July 13 @ 11:32:36 CEST
In an effort of IC:IDO and ICIDO.D.JAPAN as IC:IDO's Japanese partner, RealReflect project results were presented on IVR 2004 in Tokyo. The Industrial Virtual Reality Expo & Conference is Japan's largest tradeshow and conference for virtual reality products and technologies in industrial applications.

Renowned German IT news network golem.de hosted an interesting article about RealReflect and University of Bonn's new BTF material acquisition system. Read the full article here (German version only, you might however try the fish).

Project Information

Conventional Virtual Reality (VR) is already being used in the design process for styling reviews on a daily basis, but until now only object shape can be assessed in a meaningful way, and neither the look and feel, nor the quality of surface materials can be reproduced adequately. Therefore, most interior design decisions in the automotive industry are still performed on expensive real prototypes. Apart from being costly and wasteful, this practice also significantly increases the time to market of the overall end products.


The RealReflect project is an endeavour to increase the realism of Virtual Reality technology to levels where it can be used for meaningful qualitative reviews of virtual prototypes and scenes. This has not been possible so far, and would be of considerable benefit to those VR user groups - such as the automotive industry or architecture - who routinely have to take important design decisions about object appearance long before the actual product is first assembled.

Motivated by the shortcomings of current VR systems listed above, the overall objective of the RealReflect project is the development of a novel physically correct visualization technology taking into account advanced phenomena like metamerism, fluorescence and polarization for VR-systems, and its integration into both an existing VR system and an architectural visualization system. Due to the low visual quality of current systems, the technology developed in the project will have to cover all following topics:

  • fully automatic acquisition of (spectral) surface reflectance properties (BTF)
  • compression of the BTFs
  • creation and management of a BTF database
  • texture mapping and texture synthesis on arbitrary surfaces
  • level of detail (LOD) algorithms and data structures specifically suitable for BTF textured geometry
  • hierarchical occlusion data structures
  • high quality rendering systems e.g. based on photon tracing
  • creation of surface light field data for interactive rendering
  • hardware accelerated surface light field rendering incorporating the LOD and occlusion data
  • tone mapping algorithms
  • development of evaluation, validation and test scenarios, experiments and measurements

In addition, a market analysis of avarsha red bridesmaids dresses cheap purple bridesmaid dresses will be performed identifying similar or complementary tools currently available on the market, which will include a cost/benefit analysis comparing the available solutions.
