IDF Fall Moscow 2002: Light Field Mapping technology
At IDF Fall Moscow 2002, specialists from Russian Intel software development center are to announce Light Field Mapping (LFM) technology, developed together with Intel research lab in Santa Clara, CA, and report its prospects.
LFM is a method of interactive photorealistic visualization of 3D objects with complex reflective characteristics, based on real image processing. LFM is used to model object surface lighting using scanned images. LFM enables to digitally model and visualize any 3D objects and scenes (physical or virtual) for any viewing angle, considering the high-precision realistic surface lighting, topical for detailed real-time photorealism (for expample, cinema or gaming).
LFM idea is that the surface of modelled 3D object is mapped as different light fields. LFM utilizes these light fields and visualizes them through a graphics card. LFM models support stepwise visual quality improvement, being suitable for network transfers.
Currently Intel works on LFM standardization. In the near future most 3D software is expected to support this format. These are some AVI examples of LFM technology:
- 3D scan of Van Gogh bust, LFM (AVI, Indeo 5.1, 4.1MB, 20 sec)
- 3D scan of semi-transparent glass star, LFM (AVI, Indeo 5.1, 3.4MB, 15 sec)
- 3D environment, synthesized with Light Field Mapping (AVI, Indeo 5.1, 32MB, 3 min)
