Tools are described for preparing digital dental models for use in dental restoration production processes, along with associated systems and methods. Dental modeling is improved by supplementing views of three-dimensional models with still images of the modeled subject matter. Video data acquired during a scan of the model provides a source of still images that can be displayed alongside a rendered three-dimensional model, and the two views (model and still image) may be synchronized to provide a common perspective of the model's subject matter. This approach provides useful visual information for disambiguating surface features of the model during processing steps such as marking a margin of a prepared tooth surface for a restoration. Interactive modeling tools may be similarly enhanced. For example, tools for margin marking may synchronize display of margin lines between the still image and the model so that a user can interact with either or both of the visual representations, with changes to a margin reflected in both displays.

A method and system for interactive modeling of high-level network performance with low-level link design provides a tool for optimizing networked computing systems and their link components simultaneously. The method models a fixed portion of a network and specifies operational performance levels and power constraints. A solution is chosen for a non-fixed network portion and the network is simulated to determine link requirements and synthesizes links in conformity with the link requirements. The links are analyzed to determine performance (e.g., bandwidth) and requirements (e.g., power) and network performance is recalculated. An iterative loop from the selection of the non-fixed topology through synthesis and recalculation of link performance can be implemented to optimize the link and network design. The links may be links that use an adaptive management policy that trades off power and bandwidth in multiple operating modes and the method may be used to optimize the operating modes and/or management rules.

This invention deals with an integrated morphological system, herein called a morphological genome (morph genome), for design applications. This is the genome that encodes all form and is similar in intent to the biological genome that encodes all living things by its genetic code. The morph genome comprises a finite set of morphological genes, each gene specifies a distinct group of morphological transformations, each group of transformations is defined by a group of independent topological, geometric or other parameters. The morph genes and their parameters are mapped within an integrated higher-dimensional framework, with each parameter being represented along a vector in higher-dimensional Euclidean space. Each distinct number associated with a parameter or a group of parameters is represented by a distinct point in this space and is referenced by the higher-dimensional Cartesian co-ordinates of that point. This space uses a combination of discrete and continuous values for these parameters. The specific co-ordinates of any point in the space represent a genetic code for the specific form being mapped at that point. The entire space is a map of the morph genome and encodes all possible morphologies. The morph genome can be used as a design tool to generate known and new forms for applications in all fields of design including architecture, product design, environments and spaces, building or engineering structures, graphics, art, sculpture, technological devices, etc. The underlying method for the model for the morph genome applies to other fields of knowledge for systematically organizing and creating new concepts, structures, designs, information and taxonomies. The morph genome can also provide a basis for an integrated, interactive modeling environment for computers. It is a pedagogical tool for discovery and invention as well. Other applications include a graphic code for encryption as an alternative to numeric codes, and a system for representing numbers as integers, rational numbers and real numbers.
