Real-time LOD: Marching-cube-and- octree-based 3D Object Level-of-detail Modeling
نویسندگان
چکیده
This paper introduces the marching cube octree data structure, a new scheme for representing and generating the mesh of various level-of-details (LODs). The marching cube octree is based on the data structure of the Marching Cube algorithm [1 ], which is used to generate the mesh from the range data and the octree, this last widely used in computer graphics. Our LOD model can support adaptive simplification, compression, progressive transmission, view dependency rendering and collision detection. Our LOD mesh generation algorithm is faster than previous methods because it directly references the marching cube octree. We can construct the LOD model directly from the range data if the Marching Cube algorithm is used to generate the mesh.

3D reconstruction of real objects with high resolution shape and texture
We present a robust and accurate system for 3D reconstruction of real objects with high resolution shape and texture. Our reconstruction method is passive, the only information needed being 2D images obtained with a calibrated camera from different view angles as the object rotates on a turntable. The triangle surface model is obtained by a scheme combining octree construction and marching cube...

In this paper we present techniques for the efficient generation of a level-of-detail (LOD) data structure for large scale point-based surface representation and rendering. Our approach generates a spatial partitioning hierarchy of irregular point samples in 3D space, and we provide an efficient point-octree LOD generation algorithm. Using the concept of transformation-invariant homogeneous cov...

Volumetric sculpting has been developed for years, but real application still lacks of accuracy and suffers from tremendous space consumption. To avoid these drawbacks, a multiresolution volumetric sculpting system with feature preserving is proposed. Manipulating with extended Marching Cube algorithm (EMC), features of 3D mesh model are well preserved on multiresolution isosurface. To apply EM...

متن کاملAdaptive Multiresolution and Quality 3D Meshing from Imaging Data
This paper presents an algorithm to extract adaptive and quality 3D meshes directly from volumetric imaging data primarily Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). The extracted tetrahedral and hexahedral meshes are extensively used in the Finite Element Method (FEM). Our comprehensive approach combines bilateral and anisotropic (feature specific) diffusion filtering, with...
