Abstract: Art is a creative process. Can it possibly be supported by a computational tool? Flagg et al. [Flagg et al. 2006] proposed that capture and access technology can provide a key form of computational support for the creative process. Following the idea, a projector-based sculpture guiding system was constructed. The system can scan 3D structures, compare the difference and display the information on the physical surface. The system consists of a projector and a camera. The camera is the Point Grey Chameleon USB camera. The resolution of the image is 1280x960. The projector is the NEC M300x which a resolution of 1024x768. To keep a fixed relationship between the projector and the camera, the camera is mounted on the projector.
