Abstract

The technology problem need-resolved and application background of interactive 3D terrain building was discussed. The forces were analyzed that the terrain data point was picked up, and terrain elevation value was modified with the clicking of mouse in the 3D scene. Based on them, a system of interactive 3D terrain building was designed and implemented based on VRML. User can build 3D terrain quickly using the interactive tools provided by the system, under the circumstance of lacking true data. This technology has broad application value in real estate advertising, military sand table, showing tourist attractions, such as the bidding project.
