| Collection Description: | As one of the largest sponsors of research and development for the Nation, DOE supports thousands of research projects annually. OSTI's mission is to collect, preserve, and disseminate the scientific and technical information (STI) of the Department of Energy for use by DOE, the scientific research community, academia, U.S. industry, and the public to expand the knowledge base of science and technology. Through our collections and services, we make the results of the Department's research available to scientists, researchers, and engineers in the DOE community and beyond; as well as academia, the international science community, and science-attentive citizens. |

| Resource Title: | Development of an Immersive Environment to Aid in Automatic Mesh Generation LDRD Final Report
|
|---|
| Description: | The purpose of this work was to explore the use of immersive technologies, such as those used in synthetic environments (commordy referred to as virtual realily, or VR), in enhancing the mesh- generation process for 3-dimensional (3D) engineering models. This work was motivated by the fact that automatic mesh generation systems are still imperfect - meshing algorithms, particularly in 3D, are sometimes unable to construct a mesh to completion, or they may produce anomalies or undesirable complexities in the resulting mesh. It is important that analysts and meshing code developers be able to study their meshes effectively in order to understand the topology and qualily of their meshes. We have implemented prototype capabilities that enable such exploration of meshes in a highly visual and intuitive manner. Since many applications are making use of increasingly large meshes, we have also investigated approaches to handle large meshes while maintaining interactive response. Ideally, it would also be possible to interact with the meshing process, allowing interactive feedback which corrects problems and/or somehow enables proper completion of the meshing process. We have implemented some functionality towards this end -- in doing so, we have explored software architectures that support such an interactive meshing process. This work has incorporated existing technologies developed at SandiaNational Laboratories, including the CUBIT mesh generation system, and the EIGEN/VR (previously known as MUSE) and FLIGHT systems, which allow applications to make use of immersive technologies and advanced human computer interfaces. 1 |
