TGGeometry extension

TGGeometry.jl is a Julia wrapper around the C library libtg. which has an innovative acceleration scheme for 2-D spatial predicates (intersects, contains, etc.)

This extension provides a GeometryOps interface to that using GeometryOps' TG algorithm.

You can use any predicate like so:

import GeometryOps as GO
GO.intersects(GO.TG(), geom1, geom2)

or any other predicate in the list:

equals, intersects, disjoint, contains, within, covers, coveredby, touches

module GeometryOpsTGGeometryExt

using GeometryOps: TG
import GeometryOps as GO

using TGGeometry

Literally loop over every name in TG_PREDICATES and eval in a function implementation. This is short and sweet, and completely static, so it doesn't run at runtime but rather at compile time.

TODO: this could use some precompile statements, maybe.

for jl_fname in TGGeometry.TG_PREDICATES
    @eval GO.$jl_fname(::TG, geom1, geom2) = TGGeometry.$jl_fname(geom1, geom2)
end

end
