love::math::Math is now a singleton, so other modules can use it via
love::math::Math::instance.
Removed duplicate implementations of various rng helper functions.
ParticleSystem now uses love::math::Math's RNG.
New function: love.math.triangulate(vertices)
Accepts a table or list of x/y coordinate pairs and returns a table of tables.
The inner tables are the triangles the polygon is composed of.
Works on all *simple* polygons, i.e. a closed chain of vertices that does not
intersect itself. Attempting to triangulate non-simple polygons is undefined
behavior - in the best case it throws an error, in the worst case it returns
an invalid triangulation.
Polygons must be ordered in *clockwise order* with respect to the love
coordinate system. Attempting to triangulate a ccw polygon will throw an
error.
Examples:
triangles = love.math.triangulate(0,0, 1,1, 2,0, 2,2, 0,2)
triangles == {
{1,1, 2,0, 2,2},
{1,1, 2,2, 0,2},
{1,1, 0,2, 0,0},
}
triangles = love.math.triangulate({0,0, 1,1, 2,0, 2,2, 0,2})
-- same as above
triangles = love.math.triangulate(0,2, 2,2, 2,0, 1,1, 0,0)
-- error - polygons is in counterclockwise order
triangles = love.math.triangulate(0,0, 1,3, 2,0, 2,2, 0,2)
-- undefined behavior - polygon intersects itself (because of edge 1,3)
Contains just a RNG for now, but may include other functionality (e.g.
transforms) later on.
New Functions:
-- as in the lua math library:
love.math.randomseed(number) -- set random seed
love.math.random() -- get random number in [0:1) (uniformly distributed)
love.math.random(high) -- get integer random number in [1:high]
love.math.random(low, high) -- get integer random number in [low:high]
-- additional functions
love.math.randnormal() -- get normally distributed number with zero mean
-- and unit variance
love.math.randnormal(o) -- get normally distributed number with zero mean
-- and standard deviation `o`
love.math.randnormal(m, o) -- get normally distributed number with mean `m`
-- and standard deviation `o`
