This will simplify the code and make it more maintainable when OpenGL ES 2+ support is added, compared to using the deprecated VA functions on desktop GL and the generic VA functions on GLES.
--HG--
branch : minor
drawcalls: The number of internal draw calls made so far in the current frame.
canvasswitches: The number of times the active Canvas has been changed so far in the current frame.
texturememory: The approximate amount of video memory (in bytes) used by OpenGL textures created by Images, Canvases, and Fonts.
images: The number of active Image objects.
canvases: The number of active Canvas objects.
fonts: The number of active Font objects.
Canvases and Images are now subclasses of the new Texture class.
Added setTexture and getTexture methods for Meshes, ParticleSystems, and SpriteBatches (the old set/getImage methods are deprecated but not removed.)
Canvas texture coordinates are no longer flipped.
This allows for more diverse and complex Geometries, provided the lover understands how to use each mode. See http://escience.anu.edu.au/lecture/cg/surfaceModeling/image/surfaceModeling015.png
Changed love.graphics.newGeometry to optionally accept vertices as individual arguments instead of just a table of vertices (resolves issue #651).
Changed Geometry:setVertex to optionally accept a table containing x,y,u,v,r,g,b,a instead of just individual arguments.
Added Geometry:set/getDrawMode.
Removed the convex-check in love.graphics.newGeometry (all geometry modes have at least some form of concavity support, lovers can do their own check if needed with love.math.isConvex.)
Added an optional "vertex map" table argument to love.graphics.newGeometry (AKA a vertex index array / element array in graphics programming lingo.)
This allows lovers to change the order in which the vertices are used when drawing, or re-use a single vertex multiple times for different parts of the Geometry.
This is especially useful in the "triangles" Geometry draw mode. The vertex map lets you draw very complex (and concave) shapes / meshes without duplicating vertex data.
Added Geometry:set/getVertexMap.
A Geometry is a collection of vertices describing a non self-intersecting
(simple) polygon. In addition to screen coordinates, the vertices have
attributes for texture coordinates (s,t) and color (r,g,b,a).
It can be used as a quad, to display distorted images, or anything in between.
Added:
^^^^^^
-- geometry from table, where table has the format:
-- info = {
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- ...
-- }
geom = love.graphics.newGeometry(info)
-- convenience wrapper for quads (same as before)
geom = love.graphics.newQuad(x,y, w,h, sw,sh)
-- retrieve vertex i (1-indexed)
x,y,s,t,r,g,b,a = geom:getVertex(i)
-- set vertex i (1-indexed)
geom:setVertex(i, x,y, s,t, [r,g,b,a])
-- flip geometry
geom:flip(x, y)
Renamed:
^^^^^^^^
love.graphics.drawq() -> love.graphics.drawg()
Removed:
^^^^^^^^
quad:setViewport()
quad:getViewport()
