| Abstract: | Three-dimensional terrain visualization has been paid more and more attentions these years.This thesis mainly generalizes the techniques of three-dimensional terrain visualization,which include acquiring data,transforming projection,simplifying mes,illumination,applying textures to terrain and level of detail.Based on terrain module in MultiGenCreator2.4,terrain is newly generated by posts,then this thesis analyzes four conversion algorithms of three-dimensional terrain visualization in detail.In view of their advantages and disadvantages,this thesis chooses polymesh algorithm and generates a three-dimensional terrain of FuQing area with perfect visual effect. |
