I would like to stay away from baking and going in to delete these faces and re entering into grasshopper. Ive attached an image describing the situation. I give up! Anyway that’s the old thread in the old Forum in the old days that I had in mind (but the solution is 1M miles away from some really effective one [A Jack for all trades, that is, for every case … etc etc] NOR is written having big N of breps in mind NOR … And I need to find out the similar objects. They fail often with meshes. By the way, it’s not ideal that the primary link to that page from here lands at the bottom (end) instead of the top (beginning) of the page. If the latter, it’s better to fix that problem instead of massaging erroneous results. Anyway that’s the old thread in the old Forum in the old days that I had in mind (but the solution is 1M miles away from some really effective one [A Jack for all trades, that is, for every case … etc etc] NOR is written having big N of breps in mind NOR …, Hello Grasshopper users,Can someone help me with the following problem.I have a large scale 3D model.
Use the criteria carefully.
And I doubt this would be helpfull if I join the .gh file or rhino because th .gh file is link to a shapefile from which I extract metadata (informations)3D_site_Halles_v2.3dm (16.6 MB)
Ive tried exploding, also solving for intersections. Is there any sort of limitation to consider when trying this process?
Explode a Grasshopper mesh into its faces And I doubt this would be helpfull.
If you are interested I’ll try to find my approach(?) This is my take to the problem of splitting multiple curves in their intersections. Yeah I was annoyed by that too, just realised I could delete those ‘closed’ auto responses and now the page opens properly I think. Make the geometry in a better way that doesn’t create that condition, like a mesh growth algorithm. … geez… calm down here. First time I’m posting in a forum don’t even know how its working and what to read…. These are accessible through a double-click on the component, disallowing any kind of parametric adjustments (as with the […], All content © Copyright 2020 by Pedro de Azambuja Varela. To ease this understanding and everyday calculations, I created this simple spreadsheet in Google Docs accessible to anyone. Use the criteria carefully. Im not a programmer so i dont think i could build an algorithm that would work this out. Hey @billytalent.exe, it’s really bad form (and annoying) to always expect a personal invitation to post your model/code please!
Booleans are a combination of processes (intersect, split, delete, join). The bit mask is repeated until all elements in the data list have been evaluated. However I cannot seem to find a workflow that will delete internal ‘non-duplicate’ faces for either meshes or breps. There’s (was) a similar thread in the old GH Forum. This looks like a trick that could be useful for a grouping challenge I am working on. Where I lose it is when the new person tries to argue that posting the GH model and/or geometry isn’t relevant, when in fact, they have no idea what is relevant! Also meshes should fully intersect, should be closed, and shouldn’t have self intersecting faces, among other things. Wonder if there is option/component in gh. Some are very patient at re-explaining the same few things over and over. Sorry about that, like I said I’m new here. My only concern is that I understand how to make this work inside rhino. The Solid union command isnt processing. 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. To access this information you need to have the morphocode plugin for L-systems. However I cannot seem to find a workflow that will delete internal ‘non-duplicate’ faces for either meshes or breps. Yeah, yeah, yeah.
The Point Thank you for the insight. Can’t explain it over and over every day to people who don’t bother to read the forum a little bit before their first post, and who believe they know better about what is relevant to finding solutions. Does anybody have any idea what direction i should take for this task? Use the criteria carefully. Save the .gha file and all other included .dll files there. Ive been trying to wrap my head around this concept for quite some time now. Trying to group lines based on a shared endpoint (rather than bbox center). While using Grasshopper, I’ve … The image on the left shows the original 7 […], You can reach here for the interactive chart. Cull duplicates of any type. We’ve had the missing-referenced-data problem since forever and actually when you think about it it’s more of a bug in the *.gh file format than the fault of new users. Any suggestions? Drop the .rvb file on an open Rhino window to test. line group question_2.gh (11.6 KB). Sometimes these PDF’s are exported without much control and become several MB large, which is inconvenient to send out to some else (e-mail) or even to the cloud or a printer. In this little algorithm I build a single mesh for each face of the parent mesh.
Free for anyone to use! The COVID-19 outbreak has been the subject of various studies and infographics. If it's useful you can assign it to a button or give it a command alias. Thank you, Laurent. Remove Duplicate Points. Everyone is allowed to not know something and make at least one mistake before being judged, the problem is the small number of judges vs. the large number of ‘first offenders’. Coudnt you use a geometrywrapper like cocoon? Powered by Discourse, best viewed with JavaScript enabled, Deleting internal faces of surfaces or meshes that are not duplicates, Wrap the geometry with a mesher (cocoon, zbrush, meshlab, ect.). however i frequently am using Weaverbird so i will attach the link as well. Photoshop has a dithering filter called “Spatter”, while Gimp offers precise options for dithering purposes.
Also, in item #3 of that list ( 3. You just need […], Another take on the problem of shaping a list of numbers according to a graph visual definition. However, using an external image editor to reduce the range of a number of values is […], Researching implies producing lots of PDF’s. provided at the time (but in fact there’s no 100% working solution for any case). and splitting. The more faces you have the longer the operation. and splitting. http://www.giuliopiacentino.com/weaverbird/, Hello, just trying to respark this conversation… Has anyone tried this before? Colibri 2.0 Excel Platypus Spectacles TT Tools Video Tutorials Download. This technique consists in a probabilistic choice of values instead of a deterministic one. 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. lands at the bottom (end) instead of the top (beginning) of the page. In this case, we are culling lines based on their mid point. Remove Duplicate Points based on a tolerance; Remove Duplicate Lines based on a tolerance; Sort Curves by Direction; Group all lines that share a common node; To install: In Grasshopper, choose File > Special Folders > Components folder. Better upload your file for good answers. Groups gives the right groups, but I am unsure how to then use that list to select the groups of lines. Ive tried exploding, also solving for intersections. 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. hmmm I must say I’m new to grasshopper, and I’m not sure to understand everything. There has been alot of conversation about culling duplicate faces on surfaces and meshes. Or a result of using (or misusing) plugins?
The reason for not applying a Graph Mapper component directly deals with the way Graph Mapper has its settings adjusted.
Dithering is a technique to avoid banding or moire patterns. All to no avail. i have included a link here. Maybe there should be some kind of required test to prove that new people have read the page about How to ask effective questions before being allowed to post on the forum? S.S.Cull: Cull Pattern Cull (remove) elements in a list using a repeating bit mask. In this case, we are culling lines based on their mid point. Eventually, I want to pipe and boolean the groups of lines. Thank you, All to no avail. Hi Laurent (or anyone else on this string),
Google Sheet – Process time calculator, It is quite common to find people confused by the notion of DPI and its influence in media size.
Very challenging issue (in general) since breps are not points or lines for testing for “equality”. 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) […], Grasshopper does not seem to have the “pick region” feature from the Rhino Hatch command. The bit mask is defined as a list of Boolean values. One of the great challenges is the duplication of data (Vertices) as to feed the Faces component. That looks like just what I need. I know David, and I’m sorry for being so touchy and impatient about this. The darker red areas are the spaces i wish to delete. For some reason the Shapefile I’m using in the Meerkat plugin, have some duplicate informations.
There has been alot of conversation about culling duplicate faces on surfaces and meshes. Many of the volunteer old-timers handle it more gracefully than I do by just ignoring these threads completely. I've called it a 'sub curve on a curve' but I don't know if that's the correct way to reference it. If one 3d geo…, I found Seldup command in rhino… works fine.
Duplicated buildings shared the same verticies coordinates (see image), Is there a way to call out similar virticies, find their path (or index) and remove them from the list ? But you have something intersting here, and its maybe a part of the solution. Cull duplicates of any type. 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 […]. Maybe could you post just the mesh, so we dont have to install rabbit to look into? I created this tool because I wanted to be able to compare statistics between two countries, and I haven’t found any tool […], I created a quick Google Sheet to calculate the end time of a process based in the percentage done and time elapsed. im not sure if im using any other tools currently in this script.
180611_cull internal mesh or surface.3dm (2.9 MB). Powered by Discourse, best viewed with JavaScript enabled. I didn’t keep it, on the right it is just line coloring with Human plugin and a color wheel.
S.S.Dup: Duplicate Data Duplicate data a predefined number of times. Which result in overlapping geometries when baked. Are the duplicates in the original Rhino model? Im really interested in keeping this process inside grasshopper. McNeel employees are paid to grin and bear it while the rest of us are here for fun. Personally, I resort to booleans if there is no other options.
Seems quite impossible to clean the data list, so the only option I see is to use a component/plugin which removes overlapping geomteries… anyone know ? Subscribe to RSS Feed, Rhino modelling using SketchUp push pull technique, Explode a Grasshopper mesh into its faces. I have created such an algorithm, taking advantage of recursive computing provided by the Hoopsnake plugin. Ciao. Well … hope dies last for sure. Tip: learn how to internalize data. Cull (remove) indexed elements from a list. Not everyone has Kangaroo or Hoopsnake or Geco installed so if your file relies on those components, it might not open correctly elsewhere. True about the plug-ins, I left it out because I was hopeful that we’d have the most common plug-ins available via Yak soon, but the testing phase has lasted longer than I thought. 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. Hello
