Content Acquisition Techniques for 3D Visual Computing

Content creation for 3D graphics systems, virtual reality walkthroughs and inter-actions and multimedia presentations has been known to be a labourious and difficult problem. A lot of research is being carried out towards rapid generating detailed and realistic 3D geometric data, 2D images for textures to be mapped on them. This re-port present a brief survey of state of the art of various data, model and interaction aquisition techniques currently in use for 3D Visual Computing. More stress is put on representation and processing of the data rather than the physical processes and gadgets used to obtain the data.
