Abstract: As a platform of 3D interactive technology based on DirectX, Quest3D has very good
application space. By taking a project as an example and structuring with VC++, Quest3D and
MySQL, a visual management system based on studying the process, method and related technology
of constructing 3D interactive virtual scene with Quest3D is developed, which achieves data
synchronization and updates through service monitoring mechanism. In the virtual engineering
projection scene, users can interactively manipulate and freely walk with mouse or keyboard, search
projection message, visually warn existed problems and the preplan of emergency event handling and
so on, provideing visual solution for the engineering construction and project management.

Key words: visual management system, Quest3D, VC++, MySQL
