In this article You will find how to measure(properly) and control splines. And also how to connect splines to some reference that we may modify later.
Complex problems need really simple examples. Lets do… kitchen towel hook, something like below.
How to start? We have reference geometry to which we have to fit with our model.
Ok, lets stop for a moment. We should realize that the spline is nothing more than a few lines joined together. The only difference is that in straight line we need only two dimensions for each end to fully define position. In spline we need 4 for each point. And that’s all. Pretty easy, right? 😉 The only annoying thing is the number of dimensions. What we can do with that?
We need to check one important thing at the beginning – do we need all these points?
