Alex Szpakowski 90e86c329d Add love.data module. 
- Moved love.math.compress / decompress / decode / encode / hash to love.data.
- Changed love.data.compress/decompress to take the format argument first instead of second.
- Added love.data.newDataView. Returns a read-only subsection of an existing Data object.
- Added love.data.newByteData. Mostly useful in combination with LuaJIT's FFI as it has no extra methods currently.
- Added implementations of Lua 5.3's data packing APIs: love.data.packString / packData / unpack / getPackedSize.

Resolves issue #1336.
Resolves issue #1331.

Alex Szpakowski ac697ddb0f Clean up love’s internal Vector code a bit, and rename it to Vector2 so it’s more obvious what it is.

Alex Szpakowski 14aa6965b3 Added Transform objects to love.math (resolves issue #1228). 
- Added love.math.newTransform.
- Added love.graphics.applyTransform and love.graphics.replaceTransform.
- love.graphics.draw/print/printf, Text:add/addf, and SpriteBatch:add can accept a Transform argument.
- love.graphics.push can accept an optional Transform as a second argument, which will apply the Transform after pushing the matrix stack,
- Shader:send can accept Transform objects when sending to a mat4 uniform variable.

Alex Szpakowski cc1b9bc619 Moved most love.math functions out of the Math class, since they're pure functions.

Alex Szpakowski 734789eb93 Added love.math.encode(format, data | string [, linelength]) and love.math.decode(format, data | string). Current formats are "base64" and "hex". The optional line length only applies to base64 and specifies the maximum number of characters per line in the encoded string. 
Removed the variant of love.filesystem.newFileData which decoded a base64-encoded string since it's redundant.

Alex Szpakowski 2e9154283c Added gzip support to love.math.compress and love.math.decompress. 2015-10-02 03:18:11 -03:00
Alex Szpakowski c3fd7a25a3 Fixed some misc. compiler warnings. 2015-05-23 12:45:58 -03:00
Alex Szpakowski 97806f87c0 Replaced Simplex noise with Perlin noise for the 3D and 4D variants of love.math.noise, to avoid patent-infringement issues (resolves issue #997.) 2015-04-17 17:01:41 -03:00
Alex Szpakowski a29b349014 Added love.math.compress(data, format [, level]) and love.math.decompress(compresseddata) / love.math.decompress(compressedstring, format). 
Renamed the love.image CompressedData type to CompressedImageData.

love.math.compress returns a love.math CompressedData object which holds the newly compressed data. Currently supported formats are "lz4" and "zlib". Note that the formats are not file formats and don't compress filesystem hierarchies.

Alex Szpakowski c7b45b3505 Updated copyright for the new year 2014-12-31 19:32:43 -04:00
Alex Szpakowski d52bab4221 Updated the new module changes to use more compile/link-time checking rather than runtime checking. 2014-07-21 15:12:01 -03:00
Alex Szpakowski d07e31370d Added RandomGenerator:getState and RandomGenerator:setState (resolves issue #831.) 
getState returns an implementation-dependent string representing the current state of the RandomGenerator's PRNG. setState sets the PRNG's state to an implementation-dependent string.

Alex Szpakowski e54d771be4 Added love.math.gammaToLinear and love.math.linearToGamma for converting RGB color values from the sRGB color-space to linear and vice-versa. 2014-02-04 19:45:50 -04:00
Alex Szpakowski 3120a0e650 Goodbye 2013, hello 2014! 2014-01-03 17:28:58 -04:00
Alex Szpakowski 1c8abc74aa Renamed love.math.g/setRandomState and rng:g/setState to love.math.g/setRandomSeed and rng:g/setSeed. 
getRandomSeed now always returns the previously set random seed instead of the current (implementation-dependent) random state.
 2013-12-01 21:25:27 -04:00
Alex Szpakowski 5de43a7207 The Vertex struct is now recognized as POD by C++, also fixed the name to be consistent with other love structs 2013-09-24 11:09:18 -03:00
Alex Szpakowski 5c0066332f love.math.noise now returns values in the range of [0, 1] instead of [-1, 1] 2013-08-19 19:57:55 -03:00
Alex Szpakowski 0447d1e7c5 Changed love.math.randomnormal([mean], stddev) to love.math.randomNormal(stddev, [mean]); 
Changed love.math.randomseed(seed) to love.math.setRandomState(state) and love.math.setRandomState(low, high). Added low, high = love.math.getRandomState().

love.math.setRandomState(state) can set the random state to an integer of up to 53 bits, love.math.setRandomState(low, high) can set the random state to a 64 bit integer by using the first argument as the lower 32 bits and the second argument as the higher 32 bits.
This allows for reliable setting and saving of the state of a RNG.

vrld 19eade843c Add support for Bezier curves of arbitrary degree. 
New functions:

bezier = love.math.newBezierCurve(control-points)
degree = bezier:getDegree() -- degree = #control-points - 1
x,y = bezier:getControlPoint(pos) -- pos < 0 => string.sub semantics
bezier:setControlPoint(pos, x, y) -- pos < 0 => string.sub semantics
bezier:insertControlPoint(x,y, [pos = -1])
x,y = bezier:eval(t) -- 0 <= t <= 1
polyline = bezier:render([accuracy = 5]) -- returns a table of points

Example:

function love.load()
	b = love.math.newBezierCurve(10,10, 80,400, 380,400, 470,10)
end

function love.draw()
	if not curve then -- curve rendering is expensive-ish
		curve = b:render()
	end
	love.graphics.line(curve)
end

vrld d454be7025 Add love.math.isConvex() 
Checks whether a given polygon is convex or not.

Alex Szpakowski 63404f7097 Added love.graphics.getRendererInfo(infotype). Useful for creating more informative error reports and advanced debugging. 
Returned string can be highly system-dependent, so don't rely on its output!

infotype can be "name", "version", "vendor", or "device"
