Research topics studied in the 3D Digital Engineering Laboratory are related to the algorithms and applications that deal with three dimensional shapes and CAD data on computers and mobile devices. The focus of our research is towards the engineering applications with the fundamental knowledge of three-dimensional geometry, related computational algorithms, and mechanical engineering background. Recent research projects include the topics of haptic rendering of deformable bodies for the simulation of assembly/disassembly operations, assembly/disassembly sequence generation from 3D assembly models, triangulation algorithms for surfaces, and integrated data representation framework for CAD/CAE/CAI data. Modular design methodology for mass customization of products is under study as well with the focus on human-oriented customization.
