What is it about?
In order to display massive data accurately and in real-time, a visualization algorithm based on the viewpoint motion model is proposed. Experimental results show that under the premise of ensuring the quality of rendering, massive data can be displayed interactively, and the speed of displaying increases by 36~78%.

Why is it important?
In the field of medicine, remote sensing, and geological exploration, data acquired tends to be beyond current memory capacities. Thus, collected data cannot be loaded into the memory owing to lack of availability. For massive data, usually only 5-40% of the data is meaningful or visible. Because we can only display the visible area, there is potential for fast visualization of massive data.
Perspectives
A Hilbert-R tree is constructed to index massive data. And Further, the massive data is divided into a visible area, a potential area and an unloading area using the viewpoint motion model.
