Research on the Key Technology of the Visualization of Food Engineering Electromagnetic Signals

摘要

The related theory of GIS, scientific visualization and virtual reality based method used in this study cone approximation signal beam, isosurface and direct volume rendering visualization is realized food engineering electromagnetic signal shape and intensity of itself. In order to allow users to have a feel of the experience, this study also considered a key geographical visualization. With the technique and method of terrain data block scheduling to achieve a rapid indexing terrain blocks and realistic display; using massive image Pyramid block level model to realize the effective organization and management of image data. Finally, the visualization and geographic environment of the food engineering electromagnetic signal fusion, realize the food engineering electromagnetic signal display the result shows practical application value.
