Sneak Peek: Curve

Jeff's question was about spline usage for procedural content. My reply is that it turns out the tutorial will be all about the basics of curves and splines. I thought I'd put meshes in it as well, but it's getting too large so that'll have to wait for later. It's always fun to see tutorials change shape while you craft them. I chose Beziér curves, because once you grok those you should have no trouble grasping any other curve type. Beziér is nice to work with manually. For procedural generation, Centripetal Catmull–Rom splines are probably more convenient, because they produce paths that go through all of their control points.
