摘要： Disclosed herein is a method and apparatus for generating graphic tentacle motions. In the method, a 3D tentacle is divided into a 1D center line and a 2D surface based on information about an initial mesh of the 3D tentacle. New locations of sample points of the center line in a new frame are determined from initial locations of sample points of the center line, based on a tentacle root motion. New locations of sample points of the surface in the new frame are determined from initial locations of sample points of the surface, based on both the initial locations of the center line sample points and the tentacle root motion. The surface is coupled to the center line using the locations of the sample points of both the center line and the surface in the new frame.

摘要： A method for restoration of building structure using infinity homographies calculated based on parallelograms includes: calculating, using two or more parallelograms, an infinity homography between those cameras which refer to an arbitrary camera; restoring cameras and the building structure on an affine space using the computed infinity homography and homologous points between images; and transforming the restored result onto the metric space using constraints on orthogonality of vectors joining the restored three-dimensional points, the ratio of lengths of the vectors and intrinsic camera parameters. As a result, intrinsic camera parameters, camera positions on the metric space and the structure of the building are restored. All the restoration is possible even when intrinsic camera parameters corresponding to all the images are not constant.
