vrld 1a407a6af3 Make non-gcc compilers happy... 2013-03-13 23:09:25 +01:00
vrld ece4ff6472 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)

Alex Szpakowski d383434edf ParticleSystem:setColors now accepts multiple color arrays (issue #440) 2013-03-13 14:38:58 -03:00
Alex Szpakowski b8ec6633ab Fixed love.graphics.printf wrapping when the wrap limit is the same as the text width (issue #558) 2013-03-13 00:08:09 -03:00
Alex Szpakowski 1172d5b836 love.graphics.newScreenshot now uses the size of the current canvas (if applicable), instead of adding transparency or clipping to match the screen size 2013-03-12 20:52:24 -03:00
Alex Szpakowski d39bb315af love.graphics.newScreenshot replaces alpha with full opacity by default (issue #374, thanks Boolsheet)
Some additional overhead was added to newScreenshot because it doesn't use glPixelTransfer (not supported in ES2 / core GL3+, and like all GL functions has the slight potential to be buggy on some drivers). This choice might be revisited in the future.

Alex Szpakowski 65a3206ae4 Fixed another case of issue #538 (check for non power of two support does not cover all possibilities) 2013-03-04 14:02:35 -04:00
Alex Szpakowski 2d7dd87eb5 Removed PixelEffect compatibility functions (love.graphics.newPixelEffect is now love.graphics.newShader, etc)
Also removed love.graphics.isSupported("pixeleffect") in favor of love.graphics.isSupported("shader")
2013-03-04 14:01:04 -04:00
Alex Szpakowski 524368331d Removed love.graphics.setColorMode
- The "replace" color mode can easily be duplicated with love.graphics.setColor(255, 255, 255)
- The current color mode has no effect when a shader is active
- Color mode functionality can easily be replicated with shaders
- OpenGL ES 2 (iOS, Android, etc) does not have the functions used by love.graphics.setColorMode

Alex Szpakowski e5670e69b3 Added love.graphics.setColorMask(r, g, b, a) and love.graphics.getColorMask()
setColorMask enables or disables specific color components when rendering and clearing the screen.
For example, setColorMask(true, false, true, true) will prevent the green component of the color of all rendered objects from being written to the current frame buffer.
setColorMask is a wrapper for http://www.opengl.org/sdk/docs/man2/xhtml/glColorMask.xml
