Robust manipulation of a geometric model, that is free from computational errors, is one of the difficult proh-Iems in geometric modeling, and its algorithm is not established especially for the boundary representation. This paper proposes a new face-based data structure and a robust algorithm for processing polyhedra represented in the data structure. The(More)
In this paper, we propose a therapeutic-assisted robot for children with autism to ameliorate their skill of joint attention. The robot conducts a goal-directed based interaction to establish engagement between the child and robot in order to establish a beneficial learning environment for autistic children. An unsupervised Mixture Gaussian-based cluster(More)
In this paper, we propose a method which modifies free-form surfaces to pass through not only specified points but also specified curves with the assistance of haptic navigation. Using the method, designers of aesthetic shapes such as a car body can manipulate the model of the shape in real-time looking at its stereoscopic image and feeling its haptic(More)
• We propose a method for high-quality vertex clustering using Student-t mixture model. • Less redundant clusters, which have no small isolated fragments, have been obtained. • High-quality clusters have been obtained which correspond to the underlying surfaces. a b s t r a c t In order to robustly perform segmentation for industrial design objects measured(More)
