openingTurnfunction
A view of the solid to begin with: the cell faces the viewer, then the solid is tipped a little so that its depth shows and its neighbours on the near side can be seen. A shape with a way up (a heart, a star) is turned about its vertical axis only, so that it is seen upright, with the cell on the near side; and a solid with parts that hide parts is given a view in which the cell is not hidden, the first of a few tried.
Import it

function openingTurn(grid: SolidGrid, cell: number): QuatParameters
| Name | Type | Description |

grid | SolidGrid | The valid native flat or surface cell graph. |
cell | number | A zero-based native cell index. |
