From procedural texture to image texture (How To)

If someone need to output a “classic” bitmap file for the output of Isopod, here is a way with Nautilus,

Isopod - implicit surface tools

Hi @moby-dk Sorry for the delayed reply, I was away for a few days. Yes, I think volumetric texture generation can be an interesting application of fields, here’s a quick go at this: woodgrain.gh (19.0 KB) It does a smooth union of a bunch of capsules then maps this 1d texture(you’ll need to download it and set the file path for the image) to the scalar value: [woodline]

It will work just with 1.9.7 as my tool didn’t like 1 pixel wide image (Grasshopper tool Import Image has the same problem as mine as it puts pixel on mesh vertex)
The idea is the same as what was proposed before, I use ValueAt to measure the field on pixels.Then I tried to find the same function as Daniel to convert the image

The main problem with the texture is the transition of gradient from 1 to 0 as there is no interpolation there it leads to some problems.

I added this little tool that allows to copy on temporary folder a file from internet. Here the 1 pixel x 200 pixels wood grain texture.

And if instead of Gradient from object you feed you own gradient
