Compression and Streaming of Polygon Meshes
Compression and Streaming of Polygon Meshes by Martin Isenburg A dissertation submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Computer Science. Chapel Hill 2005 Approved by: Jack Snoeyink, Advisor Craig Gotsman, Reader Peter Lindstrom, Reader Dinesh Manocha, Committee Member Ming Lin, Committee Member ii iii ABSTRACT MARTIN ISENBURG: Compression and Streaming of Polygon Meshes (Under the direction of Jack Snoeyink) Polygon meshes provide a simple way to represent three-dimensional surfaces and are the de-facto standard for interactive visualization of geometric models. Storing large polygon meshes in standard indexed formats results in files of substantial size. Such formats allow listing vertices and polygons in any order so that not only the mesh is stored but also the particular ordering of its elements. Mesh compression rearranges vertices and polygons into an order that allows more compact coding of the incidence between vertices and predictive compression of their positions. Previous schemes were designed for triangle meshes and polygonal faces were triangulated prior to compression. I show that polygon models can be encoded more compactly by avoiding the initial triangulation step. I describe two compression schemes that achieve better compression by encoding meshes directly in their polygonal representation. I demonstrate that the same holds true for volume meshes by extending one scheme to hexahedral meshes. Nowadays scientists create polygonal meshes of incredible size. Ironically, com- pression schemes are not capable|at least not on common desktop PCs|to deal with giga-byte size meshes that need compression the most. -

Notes on Polygon Meshes 1 Basic Definitions
CMSC 23700 Introduction to Computer Graphics Handout 2 Autumn 2015 November 12 Notes on polygon meshes 1 Basic definitions Definition 1 A polygon mesh (or polymesh) is a triple (V; E; F ), where V a set of vertices (points in space) E ⊂ (V × V ) a set of edges (line segments) F ⊂ E∗ a set of faces (convex polygons) with the following properties: 1. for any v 2 V , there exists (v1; v2) 2 E such that v = v1 or v = v2. 2. for and e 2 E, there exists a face f 2 F such that e is in f. 3. if two faces intersect in space, then the vertex or edge of intersection is in the mesh. If all of the faces of a polygon mesh are triangles, then we call it a triangle mesh (trimesh). Polygons can be tessellated to form triangle meshes. Definition 2 We classify edges in a mesh based on the number of faces they are part of: • A boundary edge is part of exactly one face. • An interior edge is part of two or more faces. • A manifold edge is part of exactly two faces. • A junction edge is part of three or more faces. Junction edges are to be avoided; they can cause cracks when rendering the mesh. Definition 3 A polymesh is connected if the undirected graph G = (VF ;EE), called the dual graph, is connected, where • VF is a set of graph vertices corresponding to the faces of the mesh and • EE is a set of graph edges connecting adjacent faces. -

United States of America: The Institute of Electrical and Electronics Engineers, Inc.. Research Online is the open access institutional repository for the University of Wollongong. For further information contact the UOW Library: [email protected] Creating Simplified 3D oM dels with High Quality Textures Abstract This paper presents an extension to the KinectFusion algorithm which allows creating simplified 3D models with high quality RGB textures. This is achieved through (i) creating model textures using images from an HD RGB camera that is calibrated with Kinect depth camera, (ii) using a modified scheme to update model textures in an asymmetrical colour volume that contains a higher number of voxels than that of the geometry volume, (iii) simplifying dense polygon mesh model using quadric-based mesh decimation algorithm, and (iv) creating and mapping 2D textures to every polygon in the output 3D model. The proposed method is implemented in real-Time by means of GPU parallel processing. Visualization via ray casting of both geometry and colour volumes provides users with a real-Time feedback of the currently scanned 3D model. -

Data Sharing Implementation Based on the Information Modelfor Apparel Pattern Making Y. Tina Lee Manufacturing Systems Integration Division National Institute of Standards and Technology Gaithersburg, MD 20899-0001 ABSTRACT A standard neutral file format for facilitating apparel pattern data sharing among dissimilar CAD/ CAM systems has been long awaited by the apparel industry. The National Institute of Standards and Technology (NIST) has taken the approach to use the Standard for the Exchange of Product Model Data (STEP) methodology to develop an information model for the exchange of two- dimensional flat patterns. STEP, being developed in the International Organization for Standardization (ISO), provides a representation of product information along with the necessary mechanisms and definitions to enable product data to be exchanged amongst different computer systems and environments. -
