An inverse kinematics method for 3D figures with motion data
نویسندگان
چکیده
This paper presents a new inverse kinematics method that utilizes the motion data for realtime control and editing. The key idea is to extract parameters necessary for inverse kinematics from the motion data. These parameters are the weight matrix, which determines the motion of the redundant joints, and the transformation functions that define the motion of the end effectors. User can control the motion by dragging a body segment using a mouse, and the method calculates the new motion using the pre-computed parameters. The method enables interactive editing, warping, and retargeting character motions.

متن کاملNeural Kinematic Networks for Unsupervised Motion Retargetting
We propose a recurrent neural network architecture with a Forward Kinematics layer and cycle consistency based adversarial training objective for unsupervised motion retargetting. Our network captures high-level properties of an input motion by the forward kinematics layer and adapts them for a target character with different skeleton bone lengths (e.g., shorter, longer arms etc.). Collecting p...
متن کاملA Unified Framework for the Motion Manipulation of Articulated Figures with the TRACK System
In this paper, an interactive tool is proposed for the visualization, editing and manipulation of multiple track sequences. A sequence is associated with an articulated figure and can integrate different motion generators such as walking, inverse kinematics, and keyframing within a unified framework. The TRACK system provides a large set of tools for track space manipulations and cartesian spac...
متن کاملCompression of Human Motion Animation Using the Reduction of Interjoint Correlation
We propose two compression methods for the human motion in 3D space, based on the forward and inverse kinematics. In a motion chain, a movement of each joint is represented by a series of vector signals in 3D space. In general, specific types of joints such as end effectors often require higher precision than other general types of joints in, for example, CG animation and robot manipulation. Th...
متن کاملAn interactive motion-editing method for human animation
This paper presents an interactive motion-editing method for human animation. Through sketches, users are able to create a 3D skeleton model without any constraints. Then motion retargeting is used to adapt the original motion to the model obtained from the sketches. For supporting expression of intention, our method provides users with direct manipulation of the key parts of the model and uses...
