ABSTRACT
ABSTRACT: It is very difficult to build a 3D complex geological model using conventional modeling software. Based on geometric theories, the paper puts forward a new method to compute point cloud of a complex 3D geological model for a hillside landscape design. First according to the model pattern, the model is decomposed into several parts, and the point set of each part is calculated with the model paramaters. Then all the point sets are gathered to form the point cloud of the designed model, and a surface is generated with the point cloud using 3D modeling software. Finally the surface is used to incised the hillbody to obtain 3D landscape effect. By changing the pattern of the design and calculating of excavated and filled volume, the landscape engineering can be optimized.
