Towards a High Quality Shrink Wrap Mesh Generation Algorithm Using Mathematical Morphology

Various computational fluid dynamic simulations in engineering, such as external aerodynamics, only need the silhouette of an input geometry. Often, it is a laborious process that can take up many human hours. In addition, the CAD geometries are too complex and contain intricate features and topological holes. We showcase an effortless way to...

A Simple and Fast Hole Detection Algorithm for Triangulated Surfaces

We present a simple and fast algorithm for computing the exact holes in discrete two-dimensional manifolds embedded in a threedimensional Euclidean space. We deal with the intentionally created "through holes" or "tunnel holes" in the geometry as opposed to missing triangles. The algorithm detects the holes in the geometry directly without...

Distance field driven mean camber line extraction algorithm

</p><p class="MsoNormal">Distance fields finds a lot of applications recently in computational geometry. We propose an algorithm to extract the mean camber line of an airfoil using distance fields. This method does not require computing any geometric approximations in- side the airfoil geometry. It also does not need the airfoil coordinates...
