Sculpting: An Improved Inside-Out Scheme for All-Hexahedral Meshing

Inside-out algorithms provide the ability to generate all hexahedral meshes by first introducing a structured mesh that bounds the complete body modeled, then secondly by manipulating the exterior of this structured mesh to fit the specific boundary of the body. Such algorithms generally provide high quality meshes on the interior of the body but suffer with lower quality elements on the bounda...

Manipulation of Volumetric Solids with Applications to Sculpting

The topic of this thesis is volume graphics, and in particular techniques which are applicable to volume sculpting. A volume sculpting system is an interactive computer program for shape modelling where the shape is represented volumetrically in a 3D lattice of so–called voxels. It is argued that it is reasonable to classify the tools in a sculpting system according to whether the tools tend to...

Innovative analysis and use of high-resolution DTMs for quantitative interrogation of Earth-surface processes

This is the era of digital landscapes; the widespread availability of powerful sensing technologies has revolutionized the way it is possible to interrogate landscapes in order to understand the processes sculpting them. Vastly greater areas have now been acquired at ‘high resolution’: currently 10s of m globally to millimetric precision and accuracy locally. This permits geomorphic features to...

Classification of Scouring Form of Homogeneous and Sticky Earth Dams in Overtopping

The objective of this study was to investigate how the earth dam is destroyed due to the effect of upstream and downstream slope of the body in overflow conditions. Therefore, eight models were provided that each model is constructed from the embankment dam with different upstream and downstream slopes (1:1, 2:1) and the soil properties (Sc) on breach formation. The time and method of dam break...
