Interface ImplicitGrid3D

Interface for an implicite grid in 3D. Given (i,j,k) as integers, return the position (x,y,z)

Example

class Grid implements ImplicitGrid3D {
  spacing: number[]

  constructor(
    public readonly sizes: number[],
    dimension: number[],
    public readonly origin: number[])
  {
    this.spacing = [
      dimension[0]/sizes[0],
      dimension[1]/sizes[1],
      dimension[2]/sizes[2]
    ]
  }

  pos(i: number, j: number, k: number) {
    return [
      this.origin[0] + i*this.spacing[0],
      this.origin[1] + j*this.spacing[1],
      this.origin[2] + k*this.spacing[2]]
  }
}

const grid = new Grid()
const isos = createIsoSurfaces({
  positions: grid,
  sizes: [10,20,30],
  attribute: [.....]
})
