A method and apparatus for animating a synthetic body part. The 3D-animation system and method use a database of basic postures. In a first step, for each frame, a linear combination of the basic postures from a database of basic postures is obtained by minimizing the Euclidean distance between the displacement of critical points. The displacement information is supplied externally, and typically can be obtained by observing the displacement of physical markers placed on a moving physical body part in the real world. For instance, the synthetic body part may be an expression of a human face and the displacement data are obtained by observing physical markers placed on the face of an actor. The linear combination of the postures in the database of postures is then used to construct the desired posture. Postures are constructed for each time frame and are then displayed consecutively to provide animation. A computer readable storage medium containing a program element to direct a processor of a computer to implement the animation process is also provided.

Methods and systems for accurately locating buried defects previously detected by an inspection system are described herein. A physical mark is made on the surface of a wafer near a buried defect detected by an inspection system. In addition, the inspection system accurately measures the distance between the detected defect and the physical mark in at least two dimensions. The wafer, an indication of the nominal location of the mark, and an indication of the distance between the detected defect and the mark are transferred to a material removal tool. The material removal tool (e.g., a focused ion beam (FIB) machining tool) removes material from the surface of the wafer above the buried defect until the buried defect is made visible to an electron-beam based measurement system. The electron-beam based measurement system is subsequently employed to further analyze the defect.
