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()
Instead of letting OpenGL manage the memory mapping, allocate a temporary
block of memory upon VBO:map(). Upon VBO::unmap() the block is copied to
graphics memory using glBufferSubDataARB() and then released.
Hopefully this will fix some weird error with Windows XP + old drivers, where
VBOs can be created, but the mapped memory cannot be allocated resulting in
the sprite batch drawing nothing at all.
According to the interwebs this could actually faster than using OpenGL mapped
memory, because there is no unnecessary syncing involved.
Also improved memory usage in SpriteBatch. (No need to retain full copy of
sprites in memory. Can read that data back later to save data from OpenGL
context destruction).
