An linear octree based model for visualization of mining processes

The complex field integrated model based on linear octree was established, which can improve data storage compression ratio. Then the property threshold function and spatial threshold function were defined and applied in the fields of mining process simulation, statistical indicators and scene visualization. Lastly, the model was applied in a mine, which shows the model can effectively deal with massive mining data, improve mapping accuracy, and realize dynamic visual simulation of the mining processes, by applications of instances.
