In PotterDraw all phase-related properties are expressed as normalized angles. A normalized angle maps the full range of angles (360 degrees) to the range zero to one. The following table shows the relationship between normalized angles and degrees:
| Normalized | Degrees |
|---|---|
| 0 | 0 |
| 0.25 | 90 |
| 0.5 | 180 |
| 0.75 | 270 |
| 1 | 360 |
Values outside the range [0..1] wrap around, e.g. 1.25 wraps to 90° and −0.25 wraps to 270°.
