An Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \alpha} shape of a set of points is given by the subset of points that are reached when "scooping out" portions of space with a certain spoon whose radius is given by the parameter Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \alpha} (depending on the convention, can be the squared radius of the scoop, or its inverse). These shapes are closely related to Delaunay simplexes.
