polygonVertices :: PolygonOpts > [P2]Source
Generate the vertices of a regular polygon from the given options.
data PolygonOpts Source
PolygonOpts  

data PolygonOrientation Source
Determine how a polygon should be oriented.
Special polygons
unitSquare :: (Transformable p, PathLike p, V p ~ R2) => pSource
A sqaure with its center at the origin and sides of length 1, oriented parallel to the axes.
square :: (PathLike p, Transformable p, V p ~ R2) => Double > pSource
A sqaure with its center at the origin and sides of the given length, oriented parallel to the axes.
rect :: (PathLike p, Transformable p, V p ~ R2) => Double > Double > pSource
rect w h
is an axisaligned rectangle of width w
and height
h
, centered at the origin.
starPolygon :: (PathLike p, Transformable p, V p ~ R2) => Int > Int > pSource
starPolygon p q
creates a star polygon, where p
indicates the
number of vertices, and an edge connects every q
th vertex.
eqTriangle :: (PathLike p, Transformable p, V p ~ R2) => pSource
An equilateral triangle, with radius 1 and base parallel to the xaxis.
Other shapes
roundedRect :: (PathLike p, V p ~ R2) => R2 > Double > pSource
roundedRect v r
generates a closed trail, or closed path
centered at the origin, of an axisaligned rectangle with diagonal
v
and circular rounded corners of radius r
. r
must be
between 0
and half the smaller dimension of v
, inclusive; smaller or
larger values of r
will be treated as 0
or half the smaller
dimension of v
, respectively. The trail or path begins with the
right edge and proceeds counterclockwise.
