Reddit reviews Physics for Animators

C&C ahead, proceed if interested:


Nice start! But remember your physics. Unless there was a gust of wind mid shot, that marble would continue to bounce in place. "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. " The only force you (presumably) have in this scene is gravity, so once your marble drops, every bounce is based on that trajectory and the angle of the previous bounce. All the right ideas are here, you just need some physics to ground it. This is an awesome book that sums it up pretty neatly, as well as a lot of other stuff about physics and animation, if you're interested. Keep it up!
