Abstract:Cosmological simulation is an important research method that can help scientists understand the universe’s evolution process and verify the theoretical model. Visualization is one of the most effective ways of analyzing simulation data. Scientists can improve analysis efficiency through visualization and interactive exploration of the simulation data. With the development of supercomputers and cosmology theory, numerical simulation achieves a larger scale and higher accuracy, which brings a variety of requirements and challenges for scientific visualization. In this study, we summarize the main algorithms of visualization in cosmological simulation and demonstrate the role of visualization in analyzing the simulation data through multiple research cases. In addition, we also point out the current research hotspots and challenges.
