I suspect this might be your problem? (assuming you're seeing the same error)

yes I see the same, let me update this real quick

Now I’m stuck with this error though: I don’t really understand how the data in the tin.data array is arranged

Been looking at @fils implementation here, but still struggling to understand what’s going on <https://observablehq.com/@fil/hello-delatin>

The triangles are already being build by Delatin, so you shouldn’t need to worry with the `data` BufferArray, if I’m not mistaken… I _think_ the `triangles` Array is comprised of `vertex1,vertex2,vertex3,elevation`  quadruplets, so you may need to just build each triangle in three.js? I have not tried myself, so just speculating at first glance.

In further inspection of <@U048X1JDDHN>’s notebook, the `.triangles` contain `point1,point2,point3`` triplets, which can be looked up in `.coords` .and then the average elevation for the triangle is accessed via `.heightAt(μx,μy)` .
Seems like `THREE.PolyhedralGeometry` could be used to <https://observablehq.com/@sxywu/three-js-exploration-shapes#cell-31|build the triangles>.

Thanks Adam! Will look into this :slightly_smiling_face:

alright, update the code accordingly, but at least the indices need to fixed now
