Abstract

An algorithm to implement surface subdivision based on texture feature curves and elevation data was put forward to build multi-resolution geometric objects. The elevation information and its feature curves in the surfaces of the geometric objects were mapped to the texture of a triangle mesh. The algorithm provided a method of triangle splitting depending on the intersection of the triangle sides and the texture feature curves to create the adaptive subdivided triangle mesh. Through designing the data structure of binary-tree about the adaptive subdivided triangle mesh and developing test program, the testing indicates that the algorithm has the traits of creating model fast and maintaining better geometric feature and can meet the requirements of massive modeling of geometric objects and its real-time rendering on PC.
