cgf the choices of smooth3Dtype and smooth3Dsize need comments... |
| 15 |
|
|
cgf |
| 16 |
|
|
cgf smooth3DtypeH= 1) HORIZONTAL ALONG GRID AXIS |
| 17 |
|
|
cgf 2-3) GMREDI TYPES |
| 18 |
|
|
cgf 4) HORIZONTAL BUT WITH ROTATED AXIS |
| 19 |
|
|
cgf for now I focus on the simpler smooth3DtypeH=1 case |
