| 5 | == whats this == |
| 6 | !QuickAnimation is a wrapped lookup-table, that returns Values from Positions between 0.0 and 1.0 |
| 7 | |
| 8 | The Joke is, that one can add Key-Frames (with any values, and position between 0.0 and 1.0) and then retrieve a Value between those !KeyFrames. |
| 9 | |
| 10 | Acctually it is like a curve from 0.0 to 1.0. |

| 13 | == usage == |
| 14 | {{{ |
| 15 | #!cpp |
| 16 | QuickAnimation test; |
| 17 | |
| 18 | test.addKey(.5, 10.0); |
| 19 | test.addKey(.6, 3); |
| 20 | test.addKey(.6, 3); |
| 21 | test.changeValue(.6, 4); |
| 22 | test.addKey(.0, 1); |

| 24 | test.debug(); |
| 25 | |
| 26 | for (float f = 0.0; f < 1.0; f+= .1) |
| 27 | printf("%f - %f\n", f, test.getValue(f)); |
