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： An apparatus for detecting a pose in motion capture data includes: a motion data input unit which receives motion data of characters; a virtual marker attaching unit for forming a point cloud by attaching virtual markers to joints of an end-effector of each character; and a scaling unit for, when a frame has different character size from an a character size of an original frame to be compared is detected, scaling the character size. The apparatus further includes an ICP algorithm execution unit for finding a matching transformation matrix between the original frame and each frame of the motion data, of which character size has been scaled, by applying an ICP algorithm, and determining a frame, in which character's pose has the smallest difference from that in the original frame based on a sum of the distances between the virtual markers chosen by sampling the matched two poses.
