WebIn computer graphics, a triangle mesh is a type of polygon mesh. It comprises a set of triangles (typically in three dimensions ) that are connected by their common edges or vertices . Many graphics software packages and hardware devices can operate more efficiently on triangles that are grouped into meshes than on a similar number of triangles … 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.

WebAn alternative system is the Hierarchical Triangular Mesh, or HTM for short. While (longitude, latitude) pairs are based on establishing a point in a two-dimensional coordinate system on the surface of the earth, HTM is based on dividing the surface into almost-equal sized triangles with a unique identifier to locate something by a containing polygon.
