Reconstruction of Polygonal Faces from Large-Scale Point-Clouds of Engineering Plants

Surface Reconstruction From Problem Point Clouds

We present an algorithm for creating a CAD model of an existing physical object from a scanned point cloud containing badly scanned regions. The algorithm has a linear complexity and can be applied to processing big clouds. For the triangulation of well-scanned regions, a method from the group of greedy triangulation algorithms is used. The possibility and efficiency of use of very simple and f...

Surface Reconstruction from Unorganized 3D Point Clouds

Computer-based surfacemodels are indispensable in several fields of science and engineering. For example, the design and manufacturing of vehicles, such as cars and aircrafts, would not be possible without sophisticated CAD and simulation tools predicting the behavior of the product. On the other hand, designers often do not like working on virtual models, though sophisticated tools, like immer...

Spectral Surface Reconstruction from Noisy Point Clouds

1. Briefly summarize the paper’s contributions. Does it address a new problem? Does it present a new approach? Does it show new types of results?  [AS] This method presents a new approach to the problem of surface reconstruction from a noisy point cloud without requiring normal information. They introduce spectral methods for partitioning graphs into the problem surface reconstruction. Their a...

Tree Branching Reconstruction from Unilateral Point Clouds

Trees are ubiquitous in natural environment and realistic models of tree are also indispensable in computer graphics and virtual reality domains. However, their complexity in geometry and topology make it a great challenge for photo-realistic tree reconstruction. Since tree trunk is the preliminary structure of trees, its modeling is a critical step which plays an important role in tree modelin...
