A geo/VolumeBuilder writes a gyroid clipped to a box into a WEIGHT attribute, and geo/VolumeTriangulate meshes it with the inside stated.

geo/VolumeBuilder
Runs the code nodes inside it once for every voxel of the volume on its first input.
Volume
Dive inside and read voxel attributes such as density with code/Attribute, work on them with any code node, and write the result back with a code/Attribute whose value input is wired. code/Globals gives the voxel's position.
The first input is the geometry it visits; the three after it are read only. To read one of them, set a code/Attribute's input index to 1, 2 or 3. An input holding points answers the point nearest to the position you give the read (or, under the same-index lookup, the point with the same index as the one being visited), and an input holding a volume is sampled smoothly at that position.
The backend picks where the code runs: on the CPU, or on the GPU as a compute shader. Both give the same result.
Parameters
| Name | Type | What it does |
|---|---|---|
| backend | UInt8 CPU · GPU | Where the code runs: CPU, or GPU as a compute shader. Both give the same result; the GPU wins on large grids. |
