I had issues with small pieces and cutting what I wanted. I wish there was a line cut tool instead of using a lasso type of tool I understand that would of been hard to implement. Creative use of the them and good job with implementation!
Actually that's a good idea and it's not hard to implement. Right now i'm recording a point whenever the mouse moves and create a polygon when click is released. I could switch it so a point is created on every click and the cut is completed when you click on or close to the starting point. Thanks!
