    • Abstract
  • To improve the common representation method of scree areas by pasting texture in 3D topographic map,we present an automatic modeling method of scree based on fully considering many impact factors such as visual effect of illumination,gravity effect,etc.The method accords with the people's spatial cognition custom.The results show that it could be better to simulate the distributive characteristics and the individual appearance of scree under the different illumination conditions and elevation conditions in scree ares.This study will be helpful to build the modeling of other similar relief symbols automatically.
