“…Sample applications for model transformations using TGGs are a conversion between the two different computer graphics file formats [2], and an approach for view consistency management in the context of multi-view visual languages [4], where views are related to an integrated model by correspondence graphs. Tools developed for typed attributed graph transformation have been used frequently to implement model transformations based on TGGs (such as Fujaba [18], AToM 3 [5], and AGG [1]).…”

Triple graph grammars have been applied and implemented as a formal basis for model transformations in a variety of application areas. They convince by special abilities in automatic derivation of forward, backward and several other transformations out of just one specified set of rules for the integrated model defined by a triple of graphs. While many case studies and all implementations, which state that they are using triple graph grammars, do not use triples of graphs, this paper presents the justification for many of them. It shows a one to one correspondence between triple graph grammars and suitable plain graph grammars, thus results and benefits of the triple case can be transferred to the plain case.Main results show the relationship between both graph transformation approaches, syntactical correctness of model transformations based on triple graph grammars and a sound and complete condition for functional behaviour. Theoretical results are elaborated on an intuitive case study for a model transformation from class diagrams to database models.

“…They consider a modified TGG version (VTGG) to keep the model and its logical views consistent [31]. Aschenbrenner and Geiger [32] developed TGG rules to convert Filmbox (FBX, a proprietary Autodesk format for 3D animation software) files to OpenSceneGraph (OSG).…”

The Singapore Government has embarked on a project to establish a three-dimensional city model and collaborative data platform for Singapore. The research herein contributes to this endeavour by developing a methodology and algorithms to automate the conversion of Building Information Models (BIM), in the Industry Foundation Classes (IFC) data format, into CityGML building models, capturing both geometric and semantic information as available in the BIM models, and including exterior as well as interior structures. We adopt a Triple Graph Grammar (TGG) to formally relate IFC and CityGML, both semantically and geometrically, and to transform a building information model, expressed as an IFC object graph, into a city model expressed as a CityGML object graph. The work pipeline includes extending the CityGML data model with an Application Domain Extension (ADE), which allows capturing information from IFC that is relevant in the geospatial context but at the same time not supported by CityGML in its standard form. In this paper, we elaborate on the triple graph grammar approach and the motivation and roadmap for the development of the ADE. While a fully complete and lossless conversion may never be achieved, this paper suggests that both a TGG and an ADE are natural choices for supporting the conversion between IFC and CityGML.

“…Use of virtual reality (VR) has been developing rapidly in the education field. The efficacy and efficiency of VR application in either an immersive or a non-immersive type, has been demonstrated for different client groups during the last few decades [1]. One reason behind why virtual reality is compelling is because it exploits our inherent capacity to experience and use three-dimensional spaces without being limited to the physical world.…”

Abstract-The project of Nansha islands digital science education software promotes the dissemination of marine culture and awareness of the oceans and provides better marine cultural services to the public. We constructed the system frame of Nansha islands digital science education software (NIDSES). NIDSES designed the function including sea culture popular science with virtual reality technology, ocean geography science somatosensory interaction, and humanistic science with game. We also elaborated the key technology and application scenarios in the NIDSES. Using NIDSES we can know the history, geography and the humanities the Nansha islands and it will be of great importance.
