hello! im very new to grasshopper (and rhino) i’ve attached what my current model looks like and the gradient/shape im trying to achieve (im struggling to achieve this exact soft-edged triangle and how to spread it the way ive sketched) . ive followed multiple tutorials but none seem to work with my model and i often struggled with how to align the shape to the surface. if anyone can help it would be greatly appreciated! thank you. (i have highlighted the surfaces i want this pattern on in red)
I managed to map your example image onto proportional sized sections of three of your roof surfaces using PreviewMat(Custom Preview Materials) from the human plugin, as suggested in this thread:
That plugin is apparently not supported in R8 so had to save your Rhino model as R7 to do it.
I used Image Sampler to create a surface from points, then intersected a plane to get edge curves for the holes, mapped them to roof surfaces from your model in which I cut the holes.
Really? I thought you were trying to create a similar gradient mesh rather than just copy the image. I had to reduce unit tolerance on this R7 copy of the Rhino file to 0.01, though flaws remain. And it is very slow, requiring a full minute after opening the file to see anything.
Roof geometries are internalized so no need for the Rhino file, except perhaps for unit tolerance.
