Internet-based 3d Visualization Technology Research

Following the technology developn1ent of intemet and wwW infOrmation epoch is comenow Traditional techno1ogy of Virtual Reality could be achieved on internet. The expressionof plane of geography information has been broken tLhrough to Web 3D that makes geographyinformation exPand in visual expression on internet.In accordance with the limitation of performance of traditionaI Wrtual ReaIity,thispaper analyZed the present research condition of WrtUal Reality in the home and abroad. Themajor prob1ems about the technoIogy of Mrtual Reality have been put forward. The system'sbocture and the newest technology of Web has been introduced. In al1usion to the featUreand requires of WrtUal Reality the resolved program about distribution has been put forward.This paPer has discussed the development course. present condition. princip1e. major ideas.smictUre and the aPp1ication of itS explorer plug in in Vrmal Reality of VRML, and theobject oriented programming based on ng has been realized. In accordance with thespecia1 requires of urban 1andscaPe based on na, the modeling method Web 3d and p1anabout 3D plug in have been put forward.Finally, the imitating eXPerimentS on landscaPe with VRML urban have been put upunder this guidance of method. 3D explore p1ug in have been established, and its majorfunction and featue has been introduced. This paPer has reached the conclusion about thetechnology of Wha Reality based on internet, and has put forward itS research aim andconteni from now on.
