Integration rendering expression in Taihu Lake pollution multi-source data

In recent years, the field from different three-dimensional geological data of the scalar field and vector data visualization is relatively mature, and it realized various visualization methods based on the different data sources and data formats. However, this form of visualization technology is monotonous. It can not reveal the process of development of things that under the influence of multi-source data. So this text presents a fusion of the integrated method of visualization to achieve a more realistic display which depended on the existing multi-source vector and scalar field data representation method. This paper practice the method used of Multi-source pollution data in Taihu Lake region. By combining the lake wind field, flow field, contaminant concentration and the underwater DEM, we establish a unified three-dimensional data field, and using dynamic three-dimensional view to expression of the Taihu Lake region the spatial distribution of pollutants parameters and internal attribute information. Test results show that the integration of data from multiple sources visualization can meet the needs of simulation and decision support.
