Visualization for structures of architectural significance and objects of importance to the World’s cultural heritage has recently been receiv ing more attention. Generally, TIN and Marching Cube algorithm are used as popular modelling method for these objects. When TIN is used, to connect all the measured points, there is a problem of connecting the object which must originally deviate and mus...

3D city modelling from airborne imagery includes mainly two parts: (1) image processing procedures and (2) 3D modelling for manmade objects such as buildings, roads and other objects. Line extraction and stereo matching are usually utilized as an image processing procedures. However, there are some issues for automatic man-made object modelling. In particular, spatial data acquisition of buildi...

Traditional virtual reality environments are based on rendering all the surroundings using 3D models of objects. This requires graphically modelling the whole environment, which is usually a long and tedious task. 360-degree cameras that have recently become commercially available might be able to change that situation, as image-based virtual reality requires no graphical modelling and therefor...

We propose a sweep-based approach to the freeform deformation of three-dimensional objects. Instead of using a volume enclosing the whole object, we approximate only its deformable parts using sweep surfaces. The vertices on the object boundary are bound to the sweep surfaces and follow their deformation. Several sweep surfaces can be organized into a hierarchy so that they interact with each o...

With the emergence in 3D sensors such as laser scanners and 3D reconstruction from cameras, large 3D point clouds can now be sampled from physical objects within a scene. The raw 3D samples delivered by these sensors however, contain only a limite d degree of information about the environment the objects exist in, which means that further geometrical high-level modelling is essential. In additi...
