Decomposes a simple convex or concave polygon into triangles.
Contents
Function
Synopsis
triangles = love.math.triangulate( polygon )
Arguments
table polygon- Polygon to triangulate. Must not intersect itself.
Returns
table triangles- List of triangles the polygon is composed of, in the form of
{{x1, y1, x2, y2, x3, y3}, {x1, y1, x2, y2, x3, y3}, ...}.
Function
Synopsis
triangles = love.math.triangulate( x1, y1, x2, y2, x3, y3, ... )
Arguments
number x1- The position of the first vertex of the polygon on the x-axis.
number y1- The position of the first vertex of the polygon on the y-axis.
number x2- The position of the second vertex of the polygon on the x-axis.
number y2- The position of the second vertex of the polygon on the y-axis.
number x3- The position of the third vertex of the polygon on the x-axis.
number y3- The position of the third vertex of the polygon on the y-axis.
Returns
table triangles- List of triangles the polygon is composed of, in the form of
{{x1, y1, x2, y2, x3, y3}, {x1, y1, x2, y2, x3, y3}, ...}.
