In various embodiments, one or more control structures having sufficient detail or resolution to generate complex deformations of a computer generated model can be bound to the model. These control structures can be bound to the model in a fixed reference pose and used as intermediate control structures for controlling a variety of deformations. In one aspect, to facilitate articulation of all or a portion of the model, a set of one or more intermediate control structures may be reparameterized using one or more additional control structures. An additional control structure can be bound to an intermediate control structure dynamically at pose time. An additional control structure bound to an intermediate control structure may include only enough detail or resolution required for specific subsets of the deformations that may be produced by the intermediate controls structure.

Curve reparameterization

In various embodiments, information defining a first set of simulation primitives and a second set of simulation primitives is received at one or more computer systems. A first simulator and a second simulator are provided, using one or more processors associated with the one or more computer systems. The first simulator is based on the first set of simulation primitives and produces a first simulation. The second simulator is based on the second set of simulation primitives and produces a second simulation. A data structure is generated, using the one or more processors associated with the one or more computer systems, wherein the data structure represents dependencies between the first simulation and the second simulation.

Simulation primitives

Mesh data and other proximity information from the mesh of one model can be transferred to the mesh of another model, even with different topology and geometry. A correspondence can be created for transferring or sharing information between points of a source mesh and points of a destination mesh. Information can be 'pushed through' the correspondence to share or otherwise transfer data from one mesh to its designated location at another mesh. Correspondences can be authored on a source mesh by drawing or placing one or more geometric primitives (e.g., points, lines, curves, volumes, etc.) at the source mesh and corresponding geometric primitives at the destination mesh. A collection of 'feature curves' may be placed to partition the source and destination meshes into a collection of &#x201c;feature regions&#x201d; resulting in partitions or &#x201c;feature curve networks&#x201d; for constructing correspondences between all points of one mesh and all points of another mesh.
