NOTE (very important) : there isn't a4988 driver in proteus 8 so i replaced it with l298 in simulation .

Processing
first , all distance measures will be saved in an array list then processing will use it to draw many points that will form our objects 3d model
/*
i have plenty of ideas to make this code better and easier to use but unfortunately i can't find enough time for that because of study but it's functional so i will be glad to see what is the changes you made
