Perforations based on a jpg image


#1

Hello,
I’m attempting to generate surface perforations with varying diameters based on a jpg image input. So far this is what I have:

Any suggestions would be greatly appreciated. I’ve been trying to combine a tutorial for making a curtain wall composition based on a jpg input and a tutorial making perforations with varying diameters by specifying attractors attractors.


Combining 2 arcs into a single geometry for input into Geometry.DistanceTo node

Please start a new topic for the new task. This way the community will benefit from having a record of both solutions.

Sure thing Jacob. though it looks like that has already been administered. is that right?

Yes it has :slight_smile:

Thank you Vikram,
This has me off to a good start. I’ll post my final graph once I finish.

Hi Vikram,

I tried to modify your graph to use a diagrid instead of a square grid but I can’t get it to finish rendering. I must be missing something somewhere. Could you please take a look and let me know what you think?

Thanks!

Here we have points corresponding to pixels in the image.
Hence the regular/square grid that is proportionate to the image dimensions

Not clear as to what yo’re trying to achieve. You’ll need to elaborate.
There may be a simpler approach than complicating the grid :expressionless:

Thanks for getting back to me Vikram.
I’m trying to achieve a transition from the perforation grid pattern in the image on the right (which you were kind enough to share) to the perforation grid pattern on the left as is encouraged by the manufacturer I’m working with. I tried to achieve this by modifying your graph with the nodes in the “Generate diagrid” group (shown in the previous comment above.)
When I run the graph, there are no errors but it will never finish. I don’t believe it’s a hardware issue. Do you think it is a proportion issue? Please let me know if I can elaborate further.

Thanks again!
