Close| positions | The array of positions to set. |
Set the positions of all vertices in the line.
This method is preferred to SetPosition when setting all positions, as it is more efficient to set all positions using a single command than to set each position individually. Note that positionCount must be called before SetPositions. Also SetPositions ignores points with indices beyond positionCount.
See Also: positionCount property, SetPosition function.
