Plant growth modeling is one of the key issues in virtual plant research. In this paper, we mainly focus on the morphogenetic models of virtual plant. The procedures for simulation and visualization of plant morphological structure during the period of plant growth are summarized first. The techniques for data acquisition of plant morphological structure are introduced since it is the initial work...
This paper presents our ongoing work in the area of using virtual reality (VR) environments for the Integrated Systems Health Management (ISHM) of rocket engine test stands. Specifically, this paper focuses on the development of an intelligent valve model that integrates into the control center at NASA Stennis Space Center. The intelligent valve model integrates diagnostic algorithms and 3D visualizations...
The reconstruction of accurate freeform surface models of 3D scanned objects is a common task encountered in creating virtual reality environments for anatomical reconstruction, cartography, cultural artifact modeling, digital archaeology, infrastructure renewal, and computer-aided design. Difficulties occur in reconstructing smooth surfaces from these scanned data sets because the acquired data is...
As the related theory and technology of digital earth has been evolved since the concept of "digital earth" put forward by U.S. Vice President Al Gore, and more and more attention has been paid to ocean exploration and usage around the world in recent years, China ocean administration, together with oceanographers, proposes the "Digital Ocean" program from the state ocean development...
The modeling and rendering of real material properties highly rely on precise data acquisition. However, it is fairly hard to gather and model the bidirectional reflectance distribution function (BRDF), which indicates the properties of real material properties. This report presents the gathering data by BRDF on the basis of linear-light source reflector. By optimizing the table of linear-light source...
