The goal of this project is to develop graphics and image-processing software for the capture, storage, search, retrieval and visualisation of 3D textile samples. The ultimate objective is to develop a web-based application that allows the user to search a database for suitable textiles and to visualise selected samples using real-time photorealistic 3D animation. The innovation in this work is the combined use of photometric stereo and real-time per-pixel rendering for the capture and visualisation of textile samples. Photometric stereo is a simple method that allows both the bump map and the albedo map of a surface texture to be captured digitally. When imported into a standard graphics program these images can be used to provide 3D models with a photorealistic appearance. We have developed software that takes advantage of the advanced rendering features of consumer graphics accelerators to produce bump mapped models in real-time. The viewer can manipulate both viewpoint and lighting to gain a deeper perception of the properties of the textile sample.I.3.7 [Computer Graphics]ThreeDimensional Graphics and RealismColourshadingshadowing and texture10.2312/vvg.20031011M.
