AWESOME! Going to use this when sampling an image into a perforated facade in my B.Arch. project. Thanks!!!

Hi Ole, Right click the circle component in the GH definition and bake the circles out into regular Rhino curves. I think this is what you're looking for. The Space bar also brings up a Bake option in the form of a baked egg icon.

Thank you for your tutorial.

Hi Rodolfo, Yes, you can use other curve shapes from either referenced geometry or other GH components. Then adjust the scale or size of these using the image values.

Hi Ryan, Yes, use a Graph Mapper component between the Image Sampler and the Multiply or Divide. Set the Graph to Linear in the graph types for the component and reverse the direction.

Yes, but the second image is not square, so, before that, you need to do one other slider in the scale port.(other side, you have an undesire deformation there).what i dont know: how do you need to work with high resolution images and great dimensions....and in this point i see the problems in grasshopper, ...machine freeze, etc. Thanks!

it is possible to make those illusion sculptures that only appear if you stay in the right place in grasshopper???

@RhinoGuide Жыл бұрын

If I'm understanding correctly, yes... those types of illusions are based on the angle of view and in GH language that would be a vector that you could use to align objects to. I'd suggest posting to the user forum with a sample file to ask for advice if you're working on a project like this. discourse.mcneel.com/c/grasshopper/2

How do I make it so that it doesn't show the grid when I bake it?

@Socratesarchitects 11 жыл бұрын

hi, is there any way to turn an abstract image into randomly generated 3d rhino models ? what do you recommend I do to do this ?

Hello, How would I clean up my file to remove the very small holes in the totally white areas? For example, set a parameter for it to ignore areas entirely that are purely white?

@RhinoGuide 4 жыл бұрын

Hi Katie, You could test your radius values with a Smaller Than component and then use a Cull Pattern component to remove the tiny ones before making the circles. Post a GH file to the forum if that doesn't help discourse.mcneel.com/

Now how to do I apply this pattern to a surface on grasshopper?

@RhinoGuide 5 жыл бұрын

Hi Roy, The easiest approach would be to use FlowAlongSrf after baking out the pattern created in GH. If you wanted to have the surface as part of the definition, you'll need to reference the point locations on the target surface to get the UV and the normal. Then use those in place of the flat grid of points. The PanelingTools plugin could also help here. Search discourse.mcneel.com/c/grasshopper for more.

Awesome tutorial! Can you tell me how can I apply this image sampling to a cilinder plane? Thanks! :)

@RhinoGuide 10 жыл бұрын

Thanks Nina, I would use FlowAlongSrf in Rhino after baking out the pattern. You could do something similar in the GH def using surface frames probably but the FlowAlongSrf command will be easier. You could ask on the Rhino user forum too for other ideas... discourse.mcneel.com/

How can we export the result as dxf to use it in other programme?

@RhinoGuide 5 жыл бұрын

'Bake' out the result from the right click menu of the last component and then select the curves in the Rhino viewport. Use Save As or Export from the File menu in Rhino after that and choose dxf format.

@olwthomas 11 жыл бұрын

hi, I'm new to GH but I did manage to do this script. However, when I want to export the sampeld image, I can't select them in Rhino, and therefor not export them out as vectors... I bet thereis a simple command, I just don't know it... Help would be much appreciated:)

You need to bake (the circles, not your brain)
