INVERSE KINEMATICS AND GEOMETRIC CONSTRAINTS FOR ARTICULATED FIGURE MANIPULATION

摘要: Computer animation of articulated figures can be tedious, largely due to the amount data which must specified at each frame. Animation techniques range from simple interpolation between keyframed figure poses higher-level algorithmic models specific movement patterns. The former provides animator with complete control over movement, whereas latter may provide only limited via some high-level parameters incorporated into model. Inverse kinematic adopted robotics literature have potential relieve detailed specification every motion parameter within a figure, while retaining if desired. This work investigates use inverse kinematics and geometric constraints as tools for animator. Previous applications algorithms conlputer are reviewed. A pair alternative suitable direct manipulation interface presented qualitatively compared. Application these enforce on during interactive is discussed. An implementation one an existing editor described, constrained creation keyframes.
