Stereo matching and visual hull are techniques that are often used in 3D reconstruction. This paper presents and evaluates implementations of these algorithms on the GPU using the CUDA architecture. Experimental results show that both, visual hull and stereo matching, have much to gain in terms of speed from the data parallel execution model.

Determinant computation is the core procedure in many important geometric algorithms, such as convex hull computations and point locations. As the dimension of the computation space grows, a higher percentage of the computation time is consumed by these predicates. In this paper we study the sequences of determinants that appear in geometric algorithms. We use dynamic determinant algorithms to ...

An experimental investigation into the performance of high speed hard chine planing hulls in irregular waves has been conducted. A new series of models representative of current design practice was developed and tested experimentally. Measurements of the rigid body motions and accelerations were made at three speeds in order to assess the influence of fundamental design parameters on the seakee...

Drag is one of the main factors in improving fuel efficiency. Various study regards to improve drag performance a planing hull amongst them stern flap. The parameters design flap are span length and angle works by changing pressure distribution over ship's bottom creating lift force on transom part. This aims analyze behavior variations towards Fridsma form. Finite Volume Method (FVM) Reynolds-...

This study examines the feasibility of designing high-speed ships with hull-form geometry suitable for planked construction, with the aim of reducing the hull construction cost. An algorithm is developed for placing prismatic planks on to a three-dimensional hull form to represent a planked construction. A number of well-known hull forms are examined using the algorithm developed in order to as...

Although catamaran configuration has been around for a longtime, it is only in the recent past that such hull forms have seen unprecedented growth in the high-speed ferry industry. One of the design challenges faced by naval architects is accurate prediction of the hydrodynamic characteristics of such vessels primarily in the areas of resistance, propulsion and seakeeping. Even though considera...
