Tetrahedron mask helpers for recursive gasket families — tetrahedron_mask_helpers • grip

Convenience constructors for the four-corner tetrahedron masks used by edges.recursive.tetrahedron.mask() and recursive.tetrahedron.mask.surface.graph(). The slots correspond to the four corner subtetrahedra created by one barycentric refinement of a tetrahedron.

Usage

mask.tetrahedron.classic()

mask.tetrahedron.corner.missing(
  omit = c("apex", "base_left", "base_right", "base_back")
)

Arguments

omit: Which tetrahedron corner is omitted in mask.tetrahedron.corner.missing().

Value

A named logical vector of length 4.

Details

The returned mask entries are ordered and named as base_left, base_right, base_back, and apex.
