    We present a system of help to the conception, creation and visualization in 3D of operation rooms in hospitals using the virtual reality. According to the type of surgery exercised, we define a better adapted solution to choose and to position surgical lights. This system can generate automatically an operating room in 3D while seizing the geometric measurements directly via a graphic interface. ... View full abstract»

    The roles of computers, multi-media, virtual environments, and rapid prototyping in the design of abstract geometrical sculptures are explored. The techniques described in this paper are the outgrowth of a six-year collaboration between Brent Collins, a wood sculptor, and Carlo Sequin, a computer scientist. They are particularly applicable to abstract geometrical sculptures, where precisely define... View full abstract»

  • Surface model generation and feature extraction for the automatic restoration-of relics

    Publication Year: 2001, Page(s):318 - 327
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1098 KB) | HTML iconHTML

    The research of a relic excavated from remains has become popular. A laser measurement device is mainly used for measuring shapes of fragments and cannot measure uneven complicated shapes. So the X-ray computed tomography which can make 3D measurement is being used as the measurement device, but the model generation still requires human intervention. We propose a procedure to automatically recover... View full abstract»

    This paper presents several different calculation methods to create 3D model of a building from photographs. Based on the principles of perspective view, we can compute the projection matrix of an image from the photo, and then all the vertices of the building can be calculated. In some cases, the photos can also be used to get data of a ruined object. This is very helpful in virtual heritage stud... View full abstract»

    Exposure therapy is a clinical treatment based on gradual and systematic exposure of phobic people to the feared object or situation a little at a time. Through repeated rehearsals, their fear decreases little by little and they become more comfortable with the stimuli. For this purpose, we developed V-Theme Park-an immersive virtual environment, in which the patients themselves construct virtual ... View full abstract»
