Draw graphics on the terminal with Braille charakters. Implements a small graphics kernel with a handfull of useful routines, like Line Bresenham and Ellipse, light 3D support and Turtle Graphics.
Additionally the PGL "Primitive Graphics Language", that will plot a graph from a string and that is supported by the implementation of a Lindenmayer algorithm to create fractals. Implementing a nice little Conway's Game of Life as an example.
Lua implementation of drawille Version 2.0 of drawille
Canvas = require "drawille"
local c = Canvas.new()
for i=0,360*4 do
if (i % 15) == 0 then
c:set(i/15, math.floor(math.sin(i*(math.pi/180))*4))
end
end
print(c:frame())
Note: Color Resolution is peer Character, not per Subpixel of the [Braille][] characters. [Braille]: http://en.wikipedia.org/wiki/Braille For usage with Curses see Examples.
Canvas = require "drawille"
local c = Canvas.new()
c.esccodes = true
for i=0,360*4 do
if (i % 15) == 0 then
local r = math.random(0,255)
local g = math.random(0,255)
local b = math.random(0,255)
c:set(i/15, math.floor(math.sin(i*(math.pi/180))*4),r,g,b)
end
