TRI {silicate}

TRI model, triangulations

Description

TRI creates a constrained triangulation using 'ear-cutting', or 'ear-clipping' of polygons. The model is a 'relational' form in that the underlying tables are linked implicitly by unique identifiers. Ear-cutting is inherently path-based, so this model is only available for path-based structures, like simple features, PATH(), PATH0() and ARC().

Usage

TRI(x, ...)

## S3 method for class 'sfc_GEOMETRYCOLLECTION'
TRI(x, ...)

## S3 method for class 'TRI'
plot(x, ..., add = FALSE)

Arguments

x

object understood by silicate (sf, sp, a silicate model, etc.)

...

current unused

add

logical create new plot (default), or add to existing

Value

TRI model with tables 'object', 'triangle', 'vertex'

Examples

tri <- TRI(minimal_mesh)
plot(tri)
