333 results about "Modeling language" patented technology

A modeling language is any artificial language that can be used to express information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure.

System and method for providing a functional virtual environment with real time extracted and transplanted images

A system and method for providing a functional virtual environment with real time extracted and transplanted images. The system includes hardware and software for providing a multi-dimensional computer generated environment and for receiving a plurality of extracted video images. The system is adapted to transplant the extracted video images into the environment in a manner that preserves the virtual metaphor thereof. In the illustrative embodiment, a realistic virtual city is created in accordance with the Virtual Reality Modeling Language (VRML) protocol. The extracted images are transplanted onto an object in the environment as a texture. In the best mode, the object is invisible. The extracted video images are streamed continuously into the environment such that a live real time interaction is enabled. The environment is networked and the system is adapted to receive multiple simultaneous streams which are transplanted and exported to enable a virtual community. Within the community, users seated in their native environment, appear to walk when navigating due to the unique teaching of the present invention by which a series of stored extracted images of the user walking are transplanted into the environment and replayed for so long as the user is navigating. A separate series is displayed to each person within a predetermined range of the walker that has the walker in his field of view depending on the viewing angle of the observer. A master copy of the environment is stored on a server and downloaded to each client on the network as part of a setup process. Thereafter, local changes in the environment are uploaded to the server and subsequently downloaded to selected clients as updates. The environment will support private areas and the system is adapted to allow extracted video streams within private environments to be sent to each person in the private environment directly, bypassing the server.

Computer Method and Apparatus for Providing Model to Model Transformation Using an MDA Approach

A Model Transformation Authoring Framework (MTAF)method and apparatus for authoring and providing model-to-model transformations from one domain to another domain is disclosed. Given a domain and a target domain, at least the given domain having a respective structured hierarchy, the invention system enables a user to specify a declarative mapping (transformation declarative) between a domain specific language modeling the given domain and a modeling language modeling the target domain. The declarative mapping models how the domain specific language modeling the given domain relates to the modeling language of the target domain. The system generates a transformation code implementation of a transformation from the given domain to the target domain. The MTAF provides to the user design decisions with respect to Specification, Transformation Rules, Rule Organization, Rule Application Control, Source-Target Relationship, Incrementality, and Directionality and Tracing. The generated transformation code is executed at runtime to perform the transformation of the domain specific language of the given domain to the modeling language of the target domain. Instances of models of the target domain resulting from the performed transformation at runtime may be output to other model transformations, to JET templates, or may be persisted, merged or chained among other post processing.

Method for constructing surgical virtual operation teaching and training system

The invention provides a method for constructing a surgical virtual operation teaching and training system. The method comprises the following concrete steps: (1) acquiring various inspection data classified according to normal people and patients, intensively storing the acquired data, and constructing an integrated male virtual human model and an integrated female virtual human model; (2) carrying out geometric modeling, computational modeling and deformation computation on medical data, and carrying out modeling on bones and soft tissues by adopting a multi-outline three-dimensional reconstruction algorithm; (3) reconstructing by adopting a three-dimensional model of 3DMAX10, mapping and giving physiological characteristics to organic tissues; (4) compiling related objects and simulated scenes of a virtual operation by virtual reality modeling language (VRML); (5) carrying out preoperative preparation in the virtual operation scenes, and checking and confirming patient information; (6) carrying out complete operational details of the actual method of the virtual operation again; (7) establishing a simulated operation teaching evaluation system; and (8) carrying out comprehensive evaluation and examination on a teacher and each trainee. In the method, the simulated operation teaching system is constructed by utilizing the virtual reality technology, thereby providing a wide and transparent simulated teaching and research platform for hospitals and medical schools.
