@@LineweightsAcademy Mmmm, it'd be nice if you could teach us all how to create one of the triangles, with a lattice, that makes an Hexagon/pentagon which create a sphere. Regards
@@LineweightsAcademy Another good one would be to make a tutorial showing how to replace the image parametrically, without having to adjust the pixel size, box size, just replacing the image. Regards
Thanks for this, I browsed through about a dozen or so forum posts and tutorials on the image sampler and this was by far the easiest to wrap my head around how the domain is functioning and how to size the results. Thank you!
Michael, thanks so much for your feedback. Glad to hear the tutorial was useful. Image sampler is definitely confusing and not always intuitive. If you have any other topics in mind and let me know, happy to make more tutorials
This is the best explanation of the image sampler I’ve seen. I didn’t know the rectangle mapping component even existed. Have you ever had issues with vertical banding errors in the image sampler? Specifically with solid black and white images? (Vertical columns of points with smaller perforations compared to the rest of the points)
HI Angus, strange how I missed your comment. Thanks for the feedback! I'm glad the tutorial helped. As for your banding, I believe that is a list management issue, somehow the values from the Image Sampler are not mapping properly to the geometry (your point grid), my gut is telling me it has something to do with how the lists are structured. I hope that helps.
Thank You for the video & thank You very much for very good sound quality & dynamics of the explanation - even at the beginning of channel career (1.68k subs) for sure it will be more soon!
Kirill! Thanks so much for the support. Yes I am hoping that these videos will be able to help a lot of people out there. If you have any requests please let me know. Best, Azhar
Once you have your image sampler, is there a way to create measurements for the blocks if I wanted to build a parametric skyline diffuser? Also, can I create some type of blueprint to see block placements and colors? Thanks!
Hi Morgan, yes of course! It's hard to answer a complex question in a RUclips comment but what I can say is that the tutorial shows you how to set up a basic image sampler, from here you can code anything you like... You can always Remap the extrusion values to any measured range and can subdivide the 'target' rectangle however you like. As with any project, you'd have to figure out how to adapt the code for your specific use.
Thank you for the video! I have a map as an image, and it has areas with distinctive colors (orange), I was wondering if image sampler component could help with extracting the position of each highlighted area from the image map?
Do you mean if you want to highlight just the areas that are Orange on the map, for example? If so, yes, although that requires more scripting. An easier workaround would be to isolate the Orange pixels in Photoshop first, and then bring that image into Grasshopper, that would be way easier. If not, see if wither the R G or B channels can help isolate the area you want in the Image Sampler component. If not, then you have to extract all RGB and compare against an Orange color's RGB and filter out the values you need.
Hello sir , first i want to say thank you for the Video... it really helps me alot... but can i ask... if i want to import these image sampler to Sketchup.. what step should i do sir? because save as doesnt reveal the grasshopper model .. thank you
Hi Petra, you would have to 'bake' the Grasshopper geometry into Rhino and export that as a compatible format for SketchUp. Sketchup by default will not open Grasshopper files. If you really need to use the Image Sampler functionality then I would work exclusively in Rhino
Great question, Mauro. You'd have to use a plugin such as Human and use their custom baking components, "Bake Geometry" and "Create Attributes" to bake geometry in color. www.food4rhino.com/en/app/human
hmm interesting. it depends, are they overlapping each other? or in separate areas of the wall? If they are in separate areas then it's best to stitch the images together in Photoshop first. if they are overlapping, it's possible to have multiple image samplers (one per image) and then adjust how each one affects the wall.
@@LineweightsAcademy They are overlapping each other. In this case I have some thermographic images and I need put all in the images on the one single wall. So, later I intend to make a simulation of the temperature during the all day in the navisworks software. Could you help me to make the multiple samplers on the same wall?
@@brunakevellyn4020 I see. So just to be clear, I understand that the multiple images are shown one at a time? in the same spot on the wall? almost like a timelapse, I guess. In this case, the answer is yes, you are switching out one image file for another. The only problem is that you have to manually select the image from the Image Sampler component. In this case, you may want to try the ShapeDiver plugin, they have an Image Sampler component as well where you can directly input the file path; this way your script can just run through a list containing all the filepaths. Send me an email at info@lineweights.coffee so i know exactly what you are talking about.
Though I'm thankful to other tutorial providers, you make by far the best, most understandable and educational videos. For my brain, at least:) Tnx
mTc thanks so much!
You are my go-to grasshopper man now! Hnads down the best tutorial on image sampler. Looking forward to checking out your other tutorials.

Is there a way to make the grid less rigid (horizontal and vertical) and more random point places?

Sir very good explanation.. but i have some problem based on the circle bz i need to control my circle dia ?
Hi Daniel, currently the Diameter of the Circles is controlled via the Domain, are you looking for another way to control it?
How would it be to map it on a not flat mesh?
