The radius indicates how far from each slat its effective |
| 49 |
|
cylindrical center resides. |

|
Each slat will be broken into as many polygons as is necessary to |
| 51 |
|
keep the delta changes in angle less than 10 degrees. |
| 52 |
|
(Note that this may result in a rather large number of polygons.)\0 |
