Join Chris Reilly for an in-depth discussion in this video Analyzing surface data, part of Learning Grasshopper.
…Let's take a look at Grasshopper's tools for analyzing surface information.…These are located under the Surface, Analysis, and…Surface Util component panels.…In my example file, I've got a surface parameter and…I've referenced that from Rhino.…I've also internalized the data so that,…that surface saves along with my Grasshopper file.…And one more thing I've done here is to make sure that I've…selected this Reparameterize option in the contextual menu.…Now, when we make a surface in Rhino,…that surface has a local coordinate system in the U and V directions.…
And the bounds of those coordinates depend on the size of the surface.…So our surface, for example, might have a U domain of something like zero to seven.…But for our analysis operations,…I'd like something more predictable than the actual size of the surface.…So, by asking Grasshopper to Reparameterize my surface,…I'll remap the U and V domains to be bounded at zero and one.…It's a little bit like asking Grasshopper to treat the surface as percentage of…
