The following quote was obtained by the news editors from the background information supplied by the inventors: "Computer animation is typically a very time consuming activity requiring computer graphics (CG) expertise and use of specialist software tools and considerable computing power. First a model of an object will be generated in the form of a 3D mesh. A CG animator will then generate and embed a skeleton inside the 3D mesh of the object being animated and paint individual bone weights onto each vertex. At runtime, motion capture data or an inverse kinematics engine drives the bones of the character, which then transforms the mesh. Depending upon the level of experience of the user and the complexity of the object being animated, this process may take hours or days.
"The embodiments described below are not limited to implementations which solve any or all of the disadvantages of known methods of computer animation."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure and it does not identify key/critical elements or delineate the scope of the specification. Its sole purpose is to present a selection of concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later.
"Methods of animating objects using the human body are described. In an embodiment, a deformation graph is generated from a mesh which describes the object. Tracked skeleton data is received which is generated from sensor data and the tracked skeleton is then embedded in the graph. Subsequent motion which is captured by the sensor result in motion of the tracked skeleton and this motion is used to define transformations on the deformation graph. The transformations are then applied to the mesh to generate an animation of the object which corresponds to the captured motion. In various examples, the mesh is generated by scanning an object and the deformation graph is generated using orientation-aware sampling such that nodes can be placed close together within the deformation graph where there are sharp corners or other features with high curvature in the object.
"Many of the attendant features will be more readily appreciated as the same becomes better understood by reference to the following detailed description considered in connection with the accompanying drawings.
DESCRIPTION OF THE DRAWINGS

"FIG. 2 shows an alternative representation of the flow diagram shown in FIG. 1;
"FIG. 3 illustrates an exemplary computing-based device in which embodiments of the methods described herein may be implemented;
"FIG. 4 is a flow diagram of an example method of generating an input mesh and a flow diagram of another example method of animating an object;
"FIG. 5 is a flow diagram of an example method of generating a deformation graph;
"FIG. 6 is a schematic diagram of a graphical user interface showing proposed links between an object and a tracked skeleton;
"FIG. 7 shows a flow diagram of an example method of attaching the skeleton to the deformation graph;
"FIG. 8 is a schematic diagram showing an example transformation applied to a series of nodes;
"FIG. 9 shows a flow diagram of a further example method of animating an object; and
"FIG. 10 shows a schematic diagram of multiple skeletons attached to a single object.
"Like reference numerals are used to designate like parts in the accompanying drawings."
