Blender 3D: Newtons Cradle tutorial, Part one


https://i.ytimg.com/vi/ozipVZ9MkZU/hqdefault.jpg



In part one of this two part tutorial we will take a look at modeling and animating the famous Newtons Cradle. As the newtons cradle is a demonstration of physics, so to is this tutorial. We’ll be using the physics engine to achieve the animation we are after. You’ll learn the basics of rigid body physics, the rigid body joint, and how to trouble shoot your way through problems that arise.

The physics engine is a very precise tool. As you will see in this this tutorial, tiny changes to the scene can have enormous effects on the physics.

In part two we will look at setting up the finished shot, adding HDR lighting, and rendering with motion blur.

  1. Your tutorial is pretty nice, yet I have trouble with completing it.
    Once I create the sphere with it's wires and try to "hang" those on the base, they will connect, but the Rigid Body Joint will only "lead" those wires as part of a very much longer pendulum, whiches origin I can't see or figure. It doesn't attach to the base pointwise. Any help?

  2. I was making this for an hour. I was making it as well as I could. Then, for some reason, the first ball and the ropes fell if it was even a little in an angle. Well, I was desperate `cause I didn`t know what to do. I searched for an answer and then. Blender crashed… Well, guess I`ll start over. And what did I learn? Save every 5 minutes…

  3. @IIxXGhostTrainXxII yeah thank you, i saw that too, just wasnt sure if it was the same thing, but my cradle seems to work fine, just has taken me 2 days to render the animation lol XD

  4. @Superboy00110011 Have you tried raising the mass on the spheres? Another problem might be that the last two balls are too close or far together, just like he said, it's all about the tweaking.
