The  geological  phenomenon  is  very  complicated  in natural. Existence  of  3D geology bodys  is  universal.  With continual  deepping  of  geoscience  developing, 3D geomodeling  has  been  though  highly  of  in  the  earth  science  world. At  present,  many  3D  geoscience  modeling  software  have  been  developed .They  have  been  applied  at many  geoscience  fields so as geology,mineral, geophysical  exploration,earthquke,enviroment and so on.This paper makes a systematical summary on 3d characteristics of composition, structure, shape, distribution of geological body. It gives a summary on developing status of 3D geomodeling software of geological structure, geological engineering,mine survey, geophyscal and so on in  internal  and  external  country. The problems of software  developing and the difficultys of 3D geomodeling in gathering, editing, explaining and using of geological data are pointed out.Advances of 3D geomodeling are set forth in 3D spatial data structure,technologys and methods,application resesrch and so on.Finally,meanings of 3D geomodeling are discussed.
