3D visualization of landslide deformation

Abstract

The deformation of landslide is usually expressed in horizontal and vertical direction separately. Based on the X, Y, Z coordinates from a real monitoring project, a method to build three-dimensional(3D) model of landslide by constructing triangulated irregular network (TIN) and extruding contour lines is proposed. The almost imperceptible displacements of monitoring points are zoomed by two kind of exaggerating methods. The deformation process is replayed using 3D animation technique.
