This definition is the interior of a cluster I created that allows for the culling of duplicate items of any type based on a criteria. In this case, we are culling lines based on their mid point. Use the criteria carefully.

This is my take to the problem of splitting multiple curves in their intersections. There may be other approaches, and there are even components inside plugins that do this, but I wanted to have my own in-house solution so I could understand what is going on. The image on the left shows the original 7 […]
If you use MacOS like me, and seem to depend on Quick Look for every file related task, you would feel GPX files could get a little love. And that is just what Vidar Bronken Gundersen did, he created a GPX Quick Look plugin which you can download from his GitHub page. If you install […]
It is quite common to find people confused by the notion of DPI and its influence in media size. DPI is nothing else than the relation between virtual dimension (pixels) and real dimension (inches/centimeters). To ease this understanding and everyday calculations, I created this simple spreadsheet in Google Docs accessible to anyone. You just need […]
Dithering is a technique to avoid banding or moire patterns. This technique consists in a probabilistic choice of values instead of a deterministic one. Photoshop has a dithering filter called “Spatter”, while Gimp offers precise options for dithering purposes. However, using an external image editor to reduce the range of a number of values is […]
In this little algorithm I build a single mesh for each face of the parent mesh. One of the great challenges is the duplication of data (Vertices) as to feed the Faces component.
A common question I get is: how to replicate a “if then else” statement in Grasshopper. Here is my take. Explanation: if “First Number” is larger than “Second Number”, then output A, else output B. Or: if (FirstNumber>SecondNumber) {A} else {B}
A friend of mine who has been a long time SketchUp user has recently asked me how to do push pull in Rhino. Here is my take: Execute the command SplitFace If you want to split by a line, simply draw it (activate Near or other OSnap recommended) You have the option to split by an existing (previously drawn) […]
Contrary to most people I meet, I am a Magic Mouse fan. I never had any wrist pain, and I love the 2D touch scroll. Having said that, the mouse comes with some incompatibilities with graphical software packages, namely Blender and Rhino Grasshopper. This post is about the latter. To make the Grasshopper canvas Zoom […]
Grasshopper does not seem to have the “pick region” feature from the Rhino Hatch command. I have created such an algorithm, taking advantage of recursive computing provided by the Hoopsnake plugin. You can download the .gh file here: FindRegion.gh The overall idea of the algorithm is to find the curve that has the shortest angle relative […]
While using Grasshopper, I’ve been many times confronted with the task of smoothly varying a list of number to achieve some formal effect through number control. Be it a curvature or height control, the problem here deals with easily transforming a list of numbers into another with some of the values smoothly changed. I decided […]
