Join Chris Reilly for an in-depth discussion in this video Analyzing curve data, part of Learning Grasshopper.
…Grasshopper has many tools for analyzing curve data.…You'll find these under the Curve Analysis Component panel.…And in this video, we'll take a look at a few of the components used for…analyzing planar curves, that is curves whose points lie all in the same plane.…We'll start with the Evaluate Curve component,…which gives us properties of a curve at a given point.…So I've already set that up here.…So, Evaluate Curve takes two inputs.…A curve to evaluate which right now flows from this curve parameter where I've…set one curve and imported from Rhino.…
So I've already done that here and…I've also internalized that curve so that it saves along with my Grasshopper file.…So Evaluate Curve also takes a second component, which is a parameter t.…This determines the point on the curve to evaluate.…So, NURBS curves have a local domain.…This is sort of like a locally defined length.…Now sometimes a curves domain will be zero to one,…other times it will be something like zero to seven.…So to make sure that we get a consistent local domain,…
