Plugin Elefront - Filter by color

Hey,

I downloaded the plugin Elefront to separate all green areas from an image.
I found the component “Filter by color” but I cannot figure out how to use it.

Can anyone help or suggest another way to do it?

Thank you!

Hi Franziska,
Elefront is an amazing plugin, but “Filter by Color” works with object color in Rhino, not pixel color in the image.

I would use the Image Sampler and evaluate the image at points. It might look somehow like this:

Hey Jonish,

Thank you for your quick reply!
What did you write into the expression at the point component at the end?

I think I just multiplied the numbers by 1000 so it shows up nicer in the model.
