Inventors:

Tony DeRose - San Rafael CA, US
Mark Meyer - San Francisco CA, US

Assignee:

Pixar - Emeryville CA

International Classification:

G06T 15/00
G09G 5/00

US Classification:

345606, 345419, 345653, 345664, 345679

Abstract:

A method for determining interior coordinates is disclosed. The method includes receiving information specifying an object having a plurality of sites and a boundary. Interior coordinates associated with each of the plurality of sites are determined based on the boundary. The interior coordinate associated with each of the plurality of sites represent a system of coordinates that satisfy several properties, including non-negativity and interior locality. At least one value associated with the plurality of sites is then interpolated using the interior coordinates.

International Classification:

G09G 5/00
G06T 15/00
G06T 17/00

US Classification:

345581, 345419, 345420

Abstract:

Systems and methods are disclosed allowing data and other information from one model to be transferred to another model. A surface correspondence between meshes of the models can be created that provides a transfer or sharing of information to include all points of one mesh and all points of the other mesh. Additionally, a volume correspondence between the models can be created to transfer information found within corresponding volumes or other n-D spaces associated with the models. Mesh information and other data at, near, or otherwise within a volume or other n-D space associated with one model can be “pushed through” the volume correspondences to transfer the data to its designated location on, at, near, or otherwise within a corresponding volume or other n-D space associated with the other model.

International Classification:

G09G 5/00

US Classification:

345581, 345419, 345420, 345423

Abstract:

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 “feature regions” resulting in partitions or “feature curve networks” for constructing correspondences between all points of one mesh and all points of another mesh.
