There are many algorithms and methods to accomplish this but all have the same general purpose of 'roughing out the edges' or 'smoothing' some data. There is reason to smooth data if there is little to no small-scale structure in the data.

WebOct 10, 2024 · The algorithm also works in a recursive way. At each iteration, it constructs a convex hull for each polygon component, then extracts the subtraction/di erence between the polygon component and its convex counterpart and uses it in the next iteration until the polygon component is small enough or its convex degree is larger than a preset threshold. Web3-Dimensional Smoothing: Catmull-Clark Subdivision. Catmull-Clark subdivision is a method to smooth a 3-dimensional polygon mesh surface by dividing the surface's polygons into smaller polygons, repositioning the previous vertices based upon adjacent vertices. The method takes each primitive polygon contained in the mesh and divides the polygon ...

Laplacian smoothing is an algorithm to smooth a polygonal mesh. For each vertex in a mesh, a new position is chosen based on local information (such as the position of neighbours) and the vertex is moved there. In the case that a mesh is topologically a rectangular grid (that is, each internal vertex is connected to four neighbours) then this operation produces the Laplacian of the mesh. More formally, the smoothing operation may be described per-vertex as: WebPolygon to H3 conversion is based on the H3 polyfill function, ... For a cleaner look, the generated vector geometries can also be smoothed using a variation of Chaikins smoothing algorithm. This includes a non-destructive simplification where the number of …
