Web7 de dez. de 2016 · 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. Web1 de dez. de 2024 · We split the 3D mesh model into shape patches, which we call shape tokens, and provide polynomial fitting representations of these patches as input to the shape Transformer. The shape token encodes local geometric information and resembles the token (word) status in NLP. The simplification of the mesh model provides a hierarchical ...

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 … WebThe Hierarchical Triangular Mesh is a multi level, recursive decomposition of the sphere. It start with an octahedron, let this be level 0. As you project the edges of the octahedron onto the (unit) spehere creates 8 spherical triangles, 4 on the Northern and 4 on the Southern hemispheres. Four of these triangles share a vertex at the pole.
