Graphmapper in Grasshopper: Control Gradients
The Graphmapper allows us to interactively control parametric gradients. Any design that includes gradual and smooth geometric transitions is built around this powerful component. In
Founder, Architect & Authorized Rhino Trainer®
Thomas Jeremy Tait is the Founder and Lead Instructor at Hopific, where he provides strategic leadership for the platform’s computational design curriculum. With over a decade of hands-on experience as a Lead Design Architect and Project Manager at internationally recognized architecture practices such as Snøhetta and NADAAA, Thomas brings a strong technical background, production-driven habits, and forward-thinking creativity to all the tutorials and programs he oversees.
Thomas began his computational design career solving practical design challenges on high-profile projects, moving quickly into training his peers at Snøhetta. Over his career, he has contributed to award-winning buildings like the Beijing Public Library and the Budapest South Gate Masterplan, logging over 5,000 professional hours in Grasshopper and successfully training more than 300 architects. As a McNeel-endorsed Authorized Rhino Trainer® (ART), Thomas specializes in teaching a streamlined, design-first approach. He loves diving into complex data trees, optimizing algorithmic workflows, and solving technical design mysteries so architects can focus on creativity instead of wrestling with the software.

To extend a curve in Grasshopper, we can use the Extend Curve (Ext) component. The component allows us to take an input curve and extend

The key to understanding Grasshopper is to understand how data trees work. To have control over the output we need to know how the objects

The Stream Filter component allows us to filter one of multiple input streams using a number, acting like a railway switch that determines which connected

One key tool for managing data flows in Grasshopper is the Stream Gate component. It works like a railway switch that controls whether the input

Dealing with duplicate points in Grasshopper can be frustrating. They are hard to spot and can disrupt lists, leading to unexpected outcomes. In Grasshopper, we

Grasshopper is a Visual Programming Interface within Rhino that allows you to create fully parametric models using Rhino’s native commands. To open Grasshopper, click the

Grasshopper has three ways to fillet a curve: Fillet at a parameter, Fillet for all sharp corners with a radius, and Fillet Distance, which fillets

Reparametrizing a curve or surface in Grasshopper, means resetting their parameters to a range of 0.00 to 1.00. If you are just starting out with
