3D World Modelling
3D world modelling (also known as "fly-throughs") allows the physical environment to be represented in the form of a spatially accurate 3D computer simulation model that allows users to move anywhere in space in real time.
Real-time visualisation systems remove the uncertainty of interpretation of two-dimensional drawings and offer increased functionality compared to solid scale models. 3D models are beneficial for analysing development potential assessment, community consultation, and visualisation of existing and proposed built environments.
3D models are built firstly by utilizing an orthophoto and digital terrain model. Buildings and other important features are captured using photogrammetric mapping to maintain the real-world coordinates of the spatial data and this data is used to build structures in a CAD environment. These structures are exported into the simulation environment along with significant vegetation and building facades.
