FBlove - fast software rendering

I always liked simplicity of framebuffer , so i created small library for drawing directly on imagedata.
Code: Select all
fb=require 'fblove_strip'(w,h)
function love.draw()
fb.fill(0xFFaa00aa)
for y=0,h-1 do for x=0,w-1do
fb.buf[y][x]=0xFFFF0000+x*y
end end
fb.refresh()
fb.draw(0,0,1)
end
Because of ffi tricks and lack of safety, it works pretty fast

Wow, for drawing directly to memory, that's a pretty impressive speed!

It does seem to consume a lot of cpu though, but cool nevertheless!

It uses not so match CPU for drawing: on reasonable resolutions, performance limited by image:refresh() (~40% cpu)
