fbLove

Love2d library for software rendering

Features

• Uses love.image like a framebuffer
• It fast.
• Can change resolution on the fly
• Provides classical ways to crash your program. buf[0][-1]=0xDEADBEEF
• Love-11.1.0

How it works

todo

Example

local wndW,wndH=love.window.getMode()
fb=require 'fblove_strip'(wndW,wndH)

function love.draw()
	for i=0,(wndW*wndH)-1 do color=fb.buf[0][i] fb.buf[0][i]=0xFF5F5F5F*i end
	fb.refresh()
	fb.draw(0,0,1)
end

Let's make this resizible

love.window.setMode(800, 600, {resizable=true, vsync=false, minwidth=320, minheight=200})
local wndW,wndH=love.window.getMode()
fb=require 'fblove_strip'(wndW,wndH)

function love.draw()
	for i=0,(wndW*wndH)-1 do color=fb.buf[0][i] fb.buf[0][i]=0xFF5F5F5F*i end
	fb.refresh()
	fb.draw(0,0,1)
end

function love.resize(w,h)
 wndW,wndH=w,h  
 fb.reinit(wndW,wndH)
end 

Let's parse triss.obj file and try rendered it ;)

function loadobj(file)
	obj.x={} obj.y={} obj.z={} obj.vnx={} obj.vny={} obj.vnz={} obj.vtu={} obj.vtv={} obj.vtw={}
	obj.fv1={} obj.fvt1={} obj.fvn1={} 
	obj.fv2={} obj.fvt2={} obj.fvn2={} 
	obj.fv3={} obj.fvt3={} obj.fvn3={} 
	obj.k={}
	obj2.vnx={} obj2.vny={} obj2.vnz={} obj2.x={} obj2.y={} obj2.z={}
	file:open('r')
	for str in file:lines() do
		
		if str:find('v ') then 
		local bb=str:gmatch('[-]?%g*%d+%g*') 
		obj.x[#obj.x+1]=tonumber(bb())
		obj.y[#obj.y+1]=tonumber(bb())
		obj.z[#obj.z+1]=tonumber(bb())
		end
...
