The spirograph is a classic tool that consists of a ring and a wheel. The wheel in placed inside the ring. After the pen is placed inside one of the holes present on the wheel, it is made to rotate with the help of the ‘teeth’ present on the edges of the ring and a wheel – much like a gear. The wheel rotates on its own axis while revolving around the center of the ring. This motion generates radially symmetric patterns. One can create different patterns with different sizes of ring and wheels.
[SPIRO]rat is a free plugin for Grasshopper (plugin for McNeel Rhinoceros3D). It generates Epitrochoids and Hypotrochoids by representing the motion of the pen in a classic spirograph.
The challenge with [SPIRO]rat’s development was translating the natural physics and mathematics of the spirograph tool to a digital equivalent. This digital spirograph had to behave like it’s physical equivalent, allowing complete control to the user over it’s various parameters and even enabling animated sequences of the pattern being drawn.
01 The spirograph is a classic tool that consists of a ring and a wheel. The wheel is placed inside the ring.
02 After the pen is placed inside one of the holes present on the wheel, it is made to rotate with the help of the 'teeth' present on the edges of the ring and a wheel - much like a gear.
[SPIRO]rat plugin reflects and encourages this workflow of computational design processes. It takes the idea of a classic tool and digitalizes it for better understanding and control of the outcome.
The tool not only gives patterns as outputs but also possibilities of parameters to get desired patterns and data corresponding to generated pattern. This helps understand the mathematical relationship between parameters.
Once the basic relationships are understood one can explore with customized patterns and shapes. The workflow strongly encourages more control over the generated design
So what can you use spirorat for? The possibility of use cases is unlimited but here we provide a few use cases to stimulate your imagination!
