The Planning Department and a private consultant developed a digital model of Hong Kong, which allows efficient data management as well as effective visual assessment of proposed developments.
“By using the techniques of real-time visualization, flythrough and walkthrough in association with the traditional presentation materials such as sketches, diagrams, illustrations and photomontages, a more realistic and conceivable experience can be conveyed to the participants.”
The model uses raster and vector based formats. The raster based format is useful for rough outline of buildings and their surrounding landscape. The vector based format helps with a more detailed study involving building facades and 3D profiles.
规划署和私人顾问公司开发香港，允许高效的数据管理，以及拟议的发展有效地视觉评估数字的模型。"素描、
关系图、 插图和 photomontages 等传统演示材料结合使用的实时可视化、 flythrough 和演练的技巧，通过更加现实和想象的经验能传送到参与者。"该模型使用栅格和矢量的格式。光栅格式用于粗略大纲的建筑物和其周围的景观。基于矢量格式可帮助更详细的研究，涉及建筑幕墙和三维轮廓。
