triply periodic minimal surface

hey Grasshopper experts.

I'm trying to create a triply periodic minimal surface in Grasshopper but I have this message in milipede component index was out of range must be non-negative and less than the size of the collection. do YOU HAVE A solution for this problem ?.

Best.

The problem is that you have to fed Xres*Yres*Zres "v" values. You fed 13 values !!!!

here the solution but they are many many script already on the forum with Isosurface. Use google first and there is also a documentation for Millipede

Box [Bounding Box]: The bounding box of the geometry
V [List of Numbers]: This list must contain Xres x Yres x Zres numbers designating the field values at each point of the notional grid inside Box. The values should be ordered in such a way so that x direction is traversed first then y and then the z layers.
Xres, Yres, Zres [Integer]: The resolution of the three dimensional grid.
IsoValue [Number]: The threshold at which to cut an iso surface through the density field.
Merge [Boolean]: If true the resulting mesh will have its coinciding vertices fused and will look smoother [it does not alter the locations of vertices it just fuses coincident vertices so that normal and hence lighting calculations are continuous and not faceted]"
