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()
