## Discussion

Discussion Creating a warp geometry grid without explicit source and destination positions automatically generates the required position arrays. For example, a 2 column by 2 row grid would create two arrays containing nine positions each, beginning at [0,0] - for the bottom left position - and ending at [1,1] - for the top left position.  |  |   |  |   |  |
