The greedy algorithm exploits the property of meshes where vertices forming small features contain less number of edges. Although, we do not aim to approximate the optimal solution in minimum vertex cover problem, the idea is to select the vertices with a large number of edges. The main purpose is to preserve the salient features in the shapes, both geometrically and visually. K, Yang., D.

Makarov,Gregory M. Each Chapter concludes with a summary of the corresponding MATLAB® modules. Therefore, the need arises to reduce the complexity of these meshes and at the same time preserving the salient features of the shape. DeCoro, N.

The technique is adopted by [8] and [9]. Z. Hence, a suitable choice for meshes with small level of details (LODs). Lin.: A Fuzzy Based Approach to Mesh Simplification.

In Edge Collapse Process, an edge is identified and collapsed to form a new vertex. Only existing edges are collapsed in this program. Includes a full-body computational human phantom with over 120 triangular surface meshes extracted from the Visible Human Project® Female dataset of the National library of Medicine and fully compatible with MATLAB® Also, no steps are taken to prevent mesh inversion after an edge collapse, which may result in the mesh folding over itself after a collapse.

It's just here for comparison's sake. This is not a particularly good algorithm. Rodriguez.: Attention Based Mesh Simplification using Distance Transforms. These PLY models and many others can be found here: http://www.melax.com/polychop/lod_demo.zip This program implements four different mesh simplification algorithms.

Varshney., D. The major challenge is preserve features while reducing the amount of data to a minimum. The technique selects vertices connected with large number of edges and makes them potential candidates for contraction according to a given cost function. The process is quite fast and the quality of the output mesh depends on the size of the grid.

Computer Graphics (SIGGRAPH’97 Proceedings), 209–216, (1997) [2].H. The performance of such techniques relies on two aspects: one is how to choose an edge for contraction, the other is where to locate the new position of the contracted edge. Therefore, it is often desirable to use simplified models and at the same time preserves the general features of the shape. Computer Graphics (SIGGRAPH’96 Proceedings), 119–128, (1996) [7].J.

After about 50% reduction, our algorithm still preserves them as compared to the other two algorithms. Mesh Simplification Viewer Download program with PLY meshes and source code here. Some of the OpenGL code is based on Jeff Molofee's OpenGL tutorials. Figure 1(d) presents the idea visually.

He has slides on his site from his talk on Subdivision surfaces, bumpmaps, displacement maps, and VIPM. His article on Extreme Detail Graphics describes how progressive meshes and other level of detail techniques can be used in a game engine. The goal is to simplify regions that are relatively flat while preserving salient features of the shape. Some common techniques are Edge Collapse (Vertex Contraction), Vertex Decimation, Vertex Clustering and Face Constriction Process.

Wu, Y. The algorithm focuses on selection of vertices with maximum number of edges and determines the contraction pair which minimizes a cost function. Towards implementation side, the future work is to implement the algorithm in C++ and reduce the execution time. Figure 1.
