Mesh Models

Abstract An interactive mesh manipulation method is presented. Utilizing a Direct Surface Manipulation technique, the tool allows the user to define a specific region on an existing mesh model and modify the vertices within this region. Specific mathematical functions are applied to allow direct, precise, and coordinated modification of the vertices. The method was implemented on a prototype interactive graphics system and has demonstrated the capability to allow quick modification of large-scale automotive CAE models. One important benefit of the tool is to significantly shorten the time needed to perform CAE-based Design of Experiments (DoE), where a series of slightly different CAE mesh models must be generated in search for optimum design parameters.

Terrain Visualization

One of the main challenges encountered by interactive graphics programmers involves presenting high-quality scenes while retaining real-time frame rates on the hardware. To achieve this, level-of-detail techniques can be employed to provide a form of control over scene quality versus performance. Several algorithms exist that allow such control, including the real-time optimally adapting mesh (ROAM) algorithm specifically aimed at terrain systems. Although ROAM provides an excellent approach to terrain visualization, it contains elements that can be difficult to implement within a game system. This paper hopes to discuss these factors and provide a more game-orientated implementation of the algorithm.

This chapter presents the motivation, background, and implementation of “Living Mandala: The Cosmic of Being 1,” an interactive graphics installation that combines real-time data, multi-cultural mandalas, scientific imagery, and cosmological symbols. Built with an open source programming language and environment, this living contemporary symbol is an exploration into uncharted territories of the human soul sculpted by our present time. Its interactive revolving graphical system visualizes our perceptions of life (microcosm) and the universe (macrocosm); our connections to ancient mythology, cosmology, and cultural heritage; and the relationships among humankind, science, technology, and nature in a globalized society. Merging rich historical, cultural, scientific imagery and symbols with real-time data and relaxing sound, this living organism alters every moment responding to the movement, color, light, sound, and temperature of its surroundings.

Quiescent Prominence

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.

Capture Techniques

We have employed cryoelectron microscopy to visualize events that occur during the freeze-drying of artificial membranes by employing real time video capture techniques. Artificial membranes or liposomes which are spherical structures within internal aqueous space are stabilized by water which provides the driving force for spontaneous self-assembly of these structures. Previous assays of damage to these structures which are induced by freeze drying reveal that the two principal deleterious events that occur are 1) fusion of liposomes and 2) leakage of contents trapped within the liposome [1]. In the past the only way to access these events was to examine the liposomes following the dehydration event. This technique allows the event to be monitored in real time as the liposomes destabilize and as water is sublimed at cryo temperatures in the vacuum of the microscope. The method by which liposomes are compromised by freeze-drying are largely unknown. This technique has shown that cryo-protectants such as glycerol and carbohydrates are able to maintain liposomal structure throughout the drying process.
