Join Chris Reilly for an in-depth discussion in this video Working with surface spheres, part of Learning Grasshopper.
…In this example we'll explore a relatively simple algorithm that takes advantage of…Grasshopper's surface analysis components to produce some pretty interesting forms.…Our algorithm essentially has three steps, first acquire a surface and…make a grid of points on it.…Then, create a sphere around each one of those points.…And finally, set the size of the sphere,…based on the surface curvature at it's center point.…So the higher the curvature, the larger the sphere.…So let's walk through building this Grasshopper definition from scratch.…First, I'll open up surface geometry.3dm from the exercise files.…This will give us a surface to work with.…Then in Grasshopper I'll create a new document.…
And I'll start by grabbing a surface parameter…from the Params geometry component panel.…And I'll right click to select set one Surface from the contextual menu.…And select my surface in Rhino.…So let's tackle the first step of our algorithm, and…that's making a grid of points over the surface.…We'll do that with the Divide Surface component,…
