Web11 de abr. de 2024 · Then, the triangular meshes are constructed from L2, and the minimum matching unit (MMU) in the triangular mesh is used instead of the traditional “node-arc” unit to measure the similarity for ... WebAbstract: We have implemented an updated Hierarchical Triangular Mesh (HTM) as the basis for a unified data model and an indexing scheme for geoscience data to address the variety challenge of Big Earth Data. In the absence of variety, the volume challenge of Big Data is relatively easily addressable with parallel processing. The more important …
Hierarchical Blind Watermarking of 3D Triangular Meshes
WebThe Hierarchical Triangular Mesh (HTM) is a method to subdivide the spherical surface into triangles of nearly equal shape and size. The HTM gives us a very efficient indexing method for objects localized on the sphere. We also developed a simple geometrical method to define an arbitrary area on the sphere which can be intersected by the HTM, returning … Web13 de fev. de 2006 · Abstract.

Web9 de abr. de 2024 · compute point normals for triangle mesh. vtkTriangleMeshPointNormals is a filter that computes point normals for a triangle mesh to enable high-performance rendering. It is a fast-path version of the vtkPolyDataNormals filter in order to be able to compute normals for triangle meshes deforming rapidly. The … WebAbstract: We present a method which is able to determine the occlusion areas appearing in a mesh-based motion estimation. The use of the motion estimation scheme based on a non-uniform hierarchical triangular mesh and the optimization of the nodal motion vectors by means of a multi-resolution differential method leads to efficient and fast motion … WebIn order for computers to display this mesh of hexagons, it must be triangulated. This thesis describes an algorithm to triangulate the multi-resolution, hierarchical hexagon mesh. The triangulation provides good triangle strips, which result in efficient rendering of the hexagon mesh, and well-proportioned triangles, which avoid rendering artifacts. floor to ceiling folding doors
