The triangulation code in\n'RTriangle' uses the method of Cheng, Dey and Shewchuk (2012,\nISBN:9781584887300). For a low-dependency alternative with\nlow-quality path-based constrained triangulation see\n and for\nhigh-quality configurable triangulation see\n. Also consider comparison\nwith the 'GEOS' lib which since version 3.10.0 includes a low\nquality polygon triangulation method that starts with ear\nclipping and refines to Delaunay.", "License": "CC BY-NC-SA 4.0", "License_restricts_use": "yes", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.2.3", "VignetteBuilder": "knitr", "Roxygen": "list(markdown = TRUE)", "URL": "https://github.com/hypertidy/sfdct,\nhttps://hypertidy.github.io/sfdct/", "BugReports": "https://github.com/hypertidy/sfdct/issues", "Config/pak/sysreqs": "libabsl-dev cmake libgdal-dev gdal-bin libgeos-dev\nlibssl-dev libproj-dev libsqlite3-dev libudunits2-dev", "Repository": "https://hypertidy.r-universe.dev", "Date/Publication": "2024-01-09 19:53:24 UTC", "RemoteUrl": "https://github.com/hypertidy/sfdct", "RemoteRef": "HEAD", "RemoteSha": "f0ec2e96442ba2438c79b85cc98b372d68b1507f", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-31 06:52:36 UTC", "User": "root" }, "Author": "Michael D.
