1、Meanwhile, the criteria of re triangulation during the simplification of triangulation net are put forward, and the re...

2、Genesis of isoline based on triangulation net and implement of ActiveX

3、Abstract: Establishing DTM, triangulation net is made of some rules, but some mistakes can take place in the part of the net.

4、In the adjustment program of triangulation net by directional condition observation, to apply the formulas of polar coordinate condition is a new way.

5、Based on ideas of triangulation network growth algorithm and partition algorithm, a triangular mesh reconstruction algorithm in dishevelled points of planar domain is presented and realized.
