A method of shape2d.

the outline of a set of segments laid end to end by direction, the characteristic shape; MATLAB’s shape2d.byFV

Syntax

cShape = shape2d.byFV(gB.F, gB.V)

In the xy plane.

cShape = shape2d.byFV(gB.F, gB.V, plane=gB.plane, frame=gB.frame)

In the plane of a map.

Description

Every segment and its antipode, sorted by the angle of its direction and summed up, give a closed, convex and centrally symmetric outline centred at the origin. An outline of more than nmax vertices is sampled down to nmax. The plane and frame keywords go to shape2d.

Input

F (n, 2) int array, the vertex indices of every segment
V (m, 2) or (m, 3) array of the vertices

Keywords

keyword default description
nmax 1024 the largest number of vertices of the outline

Output

cShape shape2d
