whats this

QuickAnimation is a wrapped lookup-table, that returns Values from Positions between 0.0 and 1.0

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.

Acctually it is like a curve from 0.0 to 1.0.

usage

  QuickAnimation test;

  test.addKey(.5, 10.0);
  test.addKey(.6, 3);
  test.addKey(.6, 3);
  test.changeValue(.6, 4);
  test.addKey(.0, 1);

  test.debug();

  for (float f = 0.0; f < 1.0; f+= .1)
    printf("%f  -  %f\n", f, test.getValue(f));

outputs:

QuickAnimation:: key at position 0.600000 already added. Use changeValue instead
QuickAnim(KeyFrames:3, Resolution:100)::(position, value) (0.000000, 1.000000)->(0.500000, 10.000000)->(0.600000, 4.000000)->

0.100000  -  2.800000
0.200000  -  4.600000
0.300000  -  6.400000
