Research of red tide visualization system based on OpenGL

Red tide harms the ecological environment. In order to reduce the occurrence of red tide phenomenon, it is necessary to study and analyze the reasons for the formation of red tides. The establishment of a set of red tide phenomenon visualization system has important significance. The paper improved inverse distance weighted interpolation algorithm based on the research on the spatial interpolation algorithm and used pseudo-color map generation technology to design and implement the red tide phenomenon visualization monitoring system. Through the visualization of marine red tide phenomenon, it can intuitively reflect the relationship between the red tide factor and the red tide occurrence, which facilitates the researchers to study the formation of red tide, and provides a theoretical basis to the red tide phenomenon prediction and management.
