Visualization for the Coherent Set of 3D Property Units
Shen Ying, RenZhong Guo et al.
There are many 3D objects with denser aggregation that they are fully/partly coherent touched with each other through shared facets, which we called coherent set of 3D objects. Visualization for 3D property unit is an effective way to understand 3D spatial occupation, location and relationship in urban space, particularly in the coherent set of 3D property units. We present a novel method to visualize coherent set of 3D property units with application in 3D cadastre. We innovatively utilise deforming or distorting technique to visualize them, taking account of both the focused 3D objects and the coherent set. This visualization approach can illustrate not only the relative locations, spatial relationships of/between them, but also the highlighted shape, location of the focused/selected 3D object. Also we try to display spatial relationship explicitly between 3D objects to preserve our spatial cognition about the spatial layout and distribution.
