With the development of virtual reality technology, the visualization of electromagnetic environment has become a hot research topic. However, the research on the electromagnetic environment of the polar environment is relatively rare. This paper focuses on 3D visualization of electromagnetic environment in snow and ice environment. Geographical environment is created from DEM data, and Longley-Rice...
The radio wave propagation model is one of the emphases in the teaching practice of Information and Communication Engineering teaching discipline. In addition to teaching the theoretical knowledge of propagation models, we also tried to apply virtual reality technology to realize electromagnetic visualization of typical propagation models in the teaching process, so that students grasp in-depth the...
We aimed to evaluate whether using sodium hyaluronate carboxymethylcellulose membrane (Seprafilm™) can facilitate assessment of hepatic microcirculation via orthogonal polarization spectroscopy (OPS) by preventing intra-abdominal adhesions and whether Seprafilm™ as a foreign material can evoke local or systemic inflammatory reactions. After the right median hepatic vein was ligated, rats received...
This paper discusses the necessity and main methods of developing the three-dimensional visual and interactive system. Then the method of combining OpenGL and 3DS MAX is chosen to build the system. System structure, data transmission and interaction were presented with UML. The realization of dynamic model, viewpoint control, real-time display and vanish and other techniques are studied to ensure...
