Detailed Description

An IFF chunk of a native animation storing an array of cubic bezier curve parameter sets.

If the lower 8 bits of a key's mInterpolation field represent the IEnums::INTERPOLATION_CUBIC_BEZIER enumeration value, the upper 24 bits have the following meaning:

  • Bits 8 to 27 (including) specify the zero-based index into this array
  • Bit 30 defines whether the start delta represents an absolute value (bit cleared) or a normalized value to be multiplied by the value difference between this key and the next one (bit set)
  • Bit 31 defines the same behavior with respect to the end delta
  • Bits 28 and 29 are unused.
