quadmesh

A quadmesh is a dense mesh describing a topologically continuous surface of 4-corner primitives. This is also known as a cell-based raster but in those contexts the corner coordinates and the continuous nature of the mesh is completely implicit. By making the dense mesh explicit we have access to every corner coordinate (not just the centres) which allows for some extra facilities over raster grids.

This package provides helpers for working with this mesh interpretation of gridded data to enable

• arbitrary reprojection of raster cells without information loss (mesh_plot).
• the corner-based interpretation of a grid (quadmesh()).
• easy plotting of grids in 3D visualization tools (quad primitives in rgl mesh3d).
• fast polygonization of individual cells, in spex::polygonize.

You can install:

• the latest released version from CRAN with

install.packages("quadmesh")

• the latest development version from Github with

devtools::install_github("mdsumner/quadmesh")
