Static 3D Triangle Mesh Compression Overview [PDF]
, 2008 3D triangle meshes are extremely used to model discrete surfaces, and almost always represented with two tables: one for geometry and another for connectivity.

Vector field processing on triangle meshes [PDF]
ACM SIGGRAPH 2016 Courses, 2015 While scalar fields on surfaces have been staples of geometry processing, the use of tangent vector fields has steadily grown in geometry processing over the last two decades: they are crucial to encoding directions and sizing on surfaces as commonly ...

Repairing triangle meshes built from scanned point cloud [PDF]
, 2007 The Reverse Engineering process consists of a succession of operations that aim at creating a digital representation of a physical model. The reconstructed geometric model is often a triangle mesh built from a point cloud acquired with a scanner ...

Decimation of triangle meshes [PDF]
ACM SIGGRAPH Computer Graphics, 1992 The polygon remains a popular graphics primitive for computer graphics application. Besides having a simple representation, computer rendering of polygons is widely supported by commercial graphics hardware and software. However, because the polygon is linear, often thousands or millions of primitives are required to capture the details of complex ...

Constructing hierarchies for triangle meshes [PDF]
IEEE Transactions on Visualization and Computer Graphics, 1998 We present a method to produce a hierarchy of triangle meshes that can be used to blend different levels of detail in a smooth fashion. The algorithm produces a sequence of meshes M/sub 0/, M/sub 1/, M/sub 2/..., M/sub n/, where each mesh M/sub i/ can be transformed to mesh M/sub i+1/ through a set of triangle-collapse operations.

Developability of triangle meshes [PDF]
ACM Transactions on Graphics, 2018 Developable surfaces are those that can be made by smoothly bending flat pieces without stretching or shearing. We introduce a definition of developability for triangle meshes which exactly captures two key properties of smooth developable surfaces, namely flattenability and presence of straight ruling lines.

On the interpolation of normal vectors for triangle meshes [PDF]
International Journal for Numerical Methods in Engineering, 2013 SUMMARYThis paper analyzes the problem arising from the need to assign information about the normal vectors to the surface at the nodes of a mesh of triangles. Meshes of triangles do not have normals uniquely defined at the nodes. A widely used technique to compute the normal direction at any given node is to compute the weighted average of the normals

Random-Accessible Compressed Triangle Meshes [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2007 With the exponential growth in size of geometric data, it is becoming increasingly important to make effective use of multilevel caches, limited disk storage, and bandwidth. As a result, recent work in the visualization community has focused either on designing sequential access compression schemes or on producing cache-coherent layouts of ...

Conformal equivalence of triangle meshes
ACM Transactions on Graphics, 2008 We present a new algorithm for conformal mesh parameterization. It is based on a precise notion of discrete conformal equivalence for triangle meshes which mimics the notion of conformal equivalence for smooth surfaces.

There are simple and robust refinements (almost) as good as Delaunay [PDF]
, 2014 A new edge-based partition for triangle meshes is presented, the Seven Triangle Quasi-Delaunay partition (7T-QD). The proposed partition joins together ideas of the Seven Triangle Longest-Edge partition (7T-LE), and the classical criteria for ...
