First try the Dilate slider to get a simple visual idea that dilating is about growing in scale (doubling, tripling, quadrupling, etc). [br]To shrink, go less than 1. Half size would be 0.5. Watch what happens when you go into a negative dilation.[br]Just for reference, to create a dilation like this, you would want to place the centerpoint of your dilation at the midpoint of the base of the object.[br][br]To better understand how to solve typical math problems which will have you dilate with the centerpoint at the origin (0,0), you should use the other slider DilateAboutOrigin.
