Make love.math a singleton. Remove code duplication. Add love.math.triangulate.

Wed, 13 Mar 2013 20:48:39 +0100

Make love.math a singleton. Remove code duplication. Add love.math.triangulate.

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)

Fix issue #437: Area-based particle spawn.

Mon, 10 Sep 2012 19:58:44 +0200

Fix issue #437: Area-based particle spawn.

New particles are spawned around the particle emitter position according to a
configurabe distribution.

New functionality:

particlesystem:setAreaSpread(distributon, x, y)
distribution, x, y = particlesystem:getAreaSpread()

Where `distribution' is one of "none", "uniform", "normal".
`x' and `y' take different meaning based on the distribution:

* none: no area spread - particles spawned at emitter position.
* uniform: particle spawned at px,py in the rectangle around emitter
position ex,ey, i.e.:
ex - x < px < ex + x, ey - y < py < ey + y,
* normal: particle position drawn from a normal/gaussian distribution
with mean ex,ey and standard deviation x,y, i.e.:
px \in N(ex, x²), py \in N(ey, y²).
