Sorry, can somebody explain real quick why this example is 3D? Or is the z component of every point just zero here?

I think the professor just wanted to show us that Catmull-Rom works for higher dimensional spaces as well

When you're interpolating points like this, what exactly defines the order of the interpolation? In addition, do you always grab the nearest two points near point P and calculate the tangent based off of that? Or is it generally determined by the order of when the points are placed in the application being used?

@sunsarah I was wondering the same thing and I think it would be based on explicit ordering. In this example, if you had drawn the curve differently, you might want it to loop back on itself by going through p2, p4, p3, then p0, which should be possible.
