We have built a framework for using 3D modelling applications in an immersive virtual environment. In this paper we compare our immersive user interface made for an existing application to its original 2D desktop counterpart. The immersive 3D user interface was built on top of a generic distributed rendering framework on a cave–like virtual reality system. A test scenario was designed for compa...

Computer generated 3D models of buildings are an important component of many computer graphics applications. Rapid and easy-to-use modelling techniques are often more important than the ability to create precise and detailed geometry. We present a sketch-based modelling tool for the rapid creation of rough 3D building models. The algorithm analyses the sketch input, extracts shape and detail in...

Modelling of a complex carving surface is the most important process for digitization of art carving such as Chinese classical furniture carving, and it is difficult to be fulfilled. However, a complex 2D curve flower pattern can be easily acquired or drawn by handcraft or a drawing software. This paper presents a quick integrative 3D modeling method of complex carving surface based on a 2D cur...

Nowadays, there are rapid developments in the fields of photogrammetry, laser scanning, computer vision and robotics, together aiming to provide highly accurate 3D data that is useful for various applications. In recent years, various LiDAR and image-based techniques have been investigated for 3D modelling because of their opportunities for fast and accurate model generation. For cultural herit...

A three-dimensional (3-D) geological model has been established for Hong Kong using existing borehole data in order to facilitate detailed site investigations future engineering projects. This study aims digitalise ground investigation Kong, develop easy-to-use tools 3-D management and visualisation, eventually establish models Kong. The modelling capabilities include retrieval processing, cros...

This project presents a digitizing process of 3D laser scanner for culture heritage. The experimental records are mainly for systematic 3D model reconstruction and digital archiving of historical scenes. The procedures of digital heritage are 3D data acquisition, 3D modelling and web-based representation which demonstrate the reconstructed results and the application of virtual scene.
