LOD Generation with Discrete Curvature Error Metric
نویسندگان
چکیده
This paper proposes a new error metric: discrete curvature error metric to generate the LOD meshes. Discrete curvature is a new formalized curvature as simplification criterion. It can represent surface shape well and be computed with geometric attributes, not any smooth approximation. Our new error metric is based on the discrete curvature so that LOD can be generated precisely, and controlled efficiently. Also it can be used a global error metric, and increase the accuracy of each level’s simplified model. We suggest that LOD should be generated not by a simplification ratio but by an error metric, because level of detail means the degree of closeness between original and simplified models. Error metric based on discrete curvature can generate the LOD meshes which are recognizable explicitly with each level and preserve overall appearance of its original model.

Surface simplification using a discrete curvature norm
This paper proposes a mesh simplification algorithm using a discrete curvature norm. Most of the simplification algorithms are using a distance metric to date. The distance metric is very efficient to measure geometric error, but it is difficult to distinguish important shape features such as a high-curvature region even though it has a small distance metric. We suggest a discrete curvature nor...
متن کاملUniform Sampling in Geodesic Metric for LOD Generation
-This paper describes a level-of-detail generation approach for large scale models. To make LODs preserve the overall appearance of original data, the presented approach is to perform uniform sampling in geodesic metric, resulting in adaptive meshes or points in Euclidean metric. Geometric attribute such as curvature help to establish geodesic metric and therefore control the sampling ratios in...
متن کاملMesh Adaptation Based on Discrete Data
This paper examines the procedure of mesh adaptation on plane using the concept of an anisotropic metric. The metric is coupled with the curvature of the solution surface and it governs the process of mesh generation. The metric values are determined from the discrete data from the current simulation step and are stored in the background mesh with the appropriate interpolation procedure. If the...
متن کاملAn Adaptive Parametric Surface Mesh Generation Method Guided by Curvatures
This work presents an adaptive mesh generation strategy for parametric surfaces. The proposed strategy is controlled by curvatures and the error measured between the analytical and discrete curvatures guides the adaptive process. The analytical curvature is a mathematical representation that models the domain, whereas the discrete curvature is an approximation of that curvature and depends dire...
متن کاملDiscrete Curvature Flow for Hyperbolic 3-Manifolds with Complete Geodesic Boundaries
Every surface in the three dimensional Euclidean space have a canonical Riemannian metric, which induces constant Gaussian curvature and is conformal to the original metric. Discrete curvature flow is a feasible way to compute such canonical metrics. Similarly, three dimensional manifolds also admit canonical metrics, which induce constant sectional curvature. Canonical metrics on 3manifolds ar...
