Trouble translating colors from Image to Hexagrid

Grasshopper
1

Hi guys,

I ran into some problems trying to color my hex meshes with image sampler, as the image proportions seem to get distorted. I tried using various bounding boxes into the image sampler domain with no luck.My image is a square but I can edit it to be whatever I need to be really, I just thought making it a square would make things easier… which might no be the case so far.

The correct image being the one on the left, and the result on the right.

Hello
you still make newbie error, if you input bad coordinate in image sampler you can’t have a precise mapping

Here I use a 0 to 1 mapping.

You can check the position using that import image

Thanks guys, image sample has always been rather cryptic to me, didn’t realize the domains ends were actual coordinates on the Rhino workspace!

Thanks @laurent_delrieu for the 0 to 1 mapping method, its nice to avoid editing the domain of the image sampler all the time!
