Heightfield Resolution Issues in GH (File Attached)

Grasshopper
1

Hello!

I’m trying to create high quality mesh heightfield data using GH. The unusual thing is that I get a noticeable grid imposed on the heightfield result.

If you adjust mesh density, the grid adjusts too, so it’s not based on the image data.

I actually get similar problems with Rhino’s native heightfield command.

Does anyone know if there is a way to solve this issue?

Thanks for your time!

the image you are sampling has size 1080 px by 1080 px, so I guess setting the mesh size to 1079 will produce a grid with 1080 samples per side, which means each pixel color will be sampled once? I don’t see issues in that case
