Examples
Polar Sorting
The 'To Polar' component analyzes the polar position of points relative to a base plane. When working with a set of disordered points that you want to organize in polar order, you can use the Phi output from this component to sort them.
Note that the sorting starts from the X-direction of the base plane, so ensure the plane is correctly oriented for your needs.
Picking Components
You have surely tried picking GH components from the component's bar above the canvas. Did you know that Grasshopper has a feature for picking multiple components? By holding the "Shift" key on your keyboard and clicking on component icons, you can see a list of picked items. After that, click on the canvas multiple times to place the selected components in order. Alternatively, you can hold the Shift key while clicking on the canvas to place all selected components at once.
Midpoint
Want to find the true middle of a curve? Here’s the catch: when you reparameterize a curve, the midpoint you get is not based on the actual length – it’s just the middle of the normalized parameter range (0 to 1)! If you want the real halfway point, you need to use the Evaluate Length component and input Length / 2 to get the precise location based on the actual geometry.
Interpolate Data
The Interpolate Data component is a powerful yet often overlooked tool among computational designers. It allows you to interpolate through a list of input data and supports various data types, including numbers, points, vectors, and colors. Additionally, you can select from four interpolation modes—Block, Linear, Cubic, and Catmull—via the component's menu.
