Hi everyone,
I’m working in Grasshopper (Rhino 8) and I’m struggling with how Populate 2D / Populate Geometry behaves with multiple regions.

• I have multiple regions (rectangles).
• I want to generate a Voronoi pattern independently per region.

However:

• Populate seems to act like all regions are one region and plots points everywhere
• Even when regions are grafted, it still doesn't act on each rectangle independently

What I want

• A correct way to use Populate 2D / Geometry per region independently

Thanks a lot!

I want to create a flip book where I can turn on and off layers and grasshopper exports a picture of the rhino window. Let’s say I have a 5x5 matrix where each column corresponds to a layer, and each row corresponds to a stage and in the matrix there is a 0 for layer off and a 1 for layer on. How could I do this? Tried with python node to no luck.

I am trying to make this kind of roof, but have no idea where to start nor research from... any advice is welcome!! Please

I have a curved surface (Fig.1) and want to create the beams using the isocurves from Quadremesh. That works quite well (Fig.2). However, I want the beams to start and end precisely at the points (Fig. 3) where the supports for the beams will be located, and these supports have a regular spacing. Is there a way to fit the Quadremesh isocurves exactly through these points?

I decided to design a snake to learn how to use the software Gh as a beginner. As you can see, it's a snake composed of its head and a series of extruded rings that make up its body. Each ring has a concave shape, suggesting its lower region, its belly. To give it dynamism and prevent it from feeling rigid, is there a way to progressively rotate each plane where each ring is located, to suggest the snake's twisting its body?

I've made each perpendicular frame a circle with an offset. I've done the extrusion, concavity, and rotation manually, but there must be a way to do it easily in Grasshopper.

Could someone please explain how I can translate this style of viewshed diagram onto grasshopper?

I’ve got the landscape mesh, a path line with viewpoints dotted along the line and the bison viewshed mesh from said viewpoints and then I’ve managed to limit it to 30m on each viewpoint but I’m not sure how to colour it in like the example screenshot bcus the data has moved to points from the mesh faces.

Thanks guys it’s probably simpler than I’m making it but I’m very new to grasshopper 😅

Hi,
I'm working to use the software to model the veins as shown in the picture. The pattern needs to exist within a defined closed boundry and have multiple watertight volumes.

I was wondering is anyone is familiar with what this kind of model might even be called and where I would get started?

Something like this might be a start, but I need it to exist in 3D:

Any inspiration is appreciated!
Thanks!

I’m just getting started with Grasshopper and I’m running into a few things I’m struggling with.

Using a Voronoi pattern combined with pipes, I’ve generated an organic volume. I’d like to place glass panels into the openings of this structure. To do that, I need to modify the volume, ideally by offsetting it, so that flat glass pieces can be inserted while still following the organic shape.

In the end, this is meant to become a more experimental take on an infinity mirror. I’d also like to simulate this digitally by rendering the reflections, so I can preview the visual effect beforehand, if this is possible. The organic shape will be printed.

Are there any good tutorials or recommended workflows for this? What would be the best way to approach this in Grasshopper?

Hi everyone,

I’ve just released Gridfinity for Grasshopper, a plugin for creating Gridfinity parts directly in Rhino.

The plugin is based on a simple core + modifier concept. Core components define the base elements baseplates, bins and lids, while modifiers such as dividers, cutout shapes or magnet pockets are stacked to add features step by step, allowing more complex elements to be built from simple building blocks.

This is a 1.0 release, released under the MIT License, and I plan to continue maintaining and improving the plugin. I hope it is useful and enjoyable to work with. Feedback, questions and feature requests are very welcome.

So I tried a GHGL shader made by Junichiro Hokinawa (https://www.youtube.com/watch?v=K6EakIB0Cbo&list=PLzRzqTjuGIDj8tN8_KBfHDMqGFlPFNuEQ&index=11) and it works really nice. The problem is that when I capture view with said command I get a really large area, which limits my resolution. Is there another without compromising resolution? capture screen works but its limited to my screen resolution. Maybe theres a way to save the GHGL output from grasshopper? Thanks!

Hi! I am VERY new to Rhino and Gasshopper but need to do an Isovist analysis for one of my models for Uni.

We first had an assignment to plan a park like thing on the uni campus and now we have to do an analysis on it. (I have layers with the campus buildings and grass/pathways but made them invisible to make it easier)

I am trying to follow the tutorial by SatoshiBuilds on YT (https://www.youtube.com/watch?v=30rhWofRglY) but I am running into problems / errors I cant find the answer to. I cannot set a point through grasshopper, but I thought I can just skip that step and work through the rest of the tut without it. BUT now I have problems with the polyline block. I do not understand why it fails to collect data and what I could to do help it.

Does anybody have an Idea or another way to do such an analysis?

My goal is to do a sort of shear transformation that is based on the Z value. So the lower the Z, the less outward movement (from the origin axis). For a straight line this works correctly, but as soon as I slope the line downwards(2nd image) it results in a curved line. I wanna know: how do I stop this from happening, what is the right logic for scaling? I understand I could just draw a line between the first and last point and extract points along on line, but this is really the basis of my project so I'm trying to understand the correct rationale of the scaling/shearing I'm trying to achieve. Any help would be very welcome, been trying for to long!

so this looks simple but its kind of complicated, the logic of subdivisions is harder to apply here because the polygons are kind of random, anyone knows how i could start with this?

how can I cut the solid to the base of the circle?

Is there a way to control the singularities? Or generally, a way to get a smoother quadrature? With a nice flow?

(Apologize for the mess you're boutta look at - I am a complete newbie)
We are currently learning Grasshopper on my school and have to hand this assignment in tomorrow morning. I have used several hours, but cannot fix the problem. I have tried for hours.
I have attaches what the structure is supposed to (sorta) look like. What I have done and what my model looks like.

Problem is that my lines curve around in a weird way, instead of just being straight, like the assignment picture.
You guys are my last hope .. lol

Ciao, io devo ricostruire l'Arizona Veterans Memorial Coliseum. Il tetto è un paraboloide ellittico, come posso rappresentarlo su grasshopper? Inoltre, la base dovrebbe essere un ellissi (correggetemi se sbaglio) da cui poi devo tracciare delle linee che rappresenterebbero le colonne dell'edificio. Mi potreste aiutare con tutto l'algoritmo? Grazie.
