List of Out of Range Types.
Out of Range Types provide several methods of extrapolating the pattern of key dots in a track. These patterns are applied to the animation outside the range of all keys in the track. The list of options is below:
One of the following values:
ORT_CONSTANT
The tracks values before or after the range of keys remains constant.
ORT_CYCLE
This causes the key pattern to repeat cyclically.
ORT_LOOP
This is the same as ORT_CYCLE with continuity.
ORT_OSCILLATE
This is referred to as "Ping-Pong" in the 3ds max user interface. This reverses the range of keys values to cause the pattern to oscillate.
ORT_LINEAR
This takes the slope at the end key in the range and extrapolate with that slope.
ORT_IDENTITY
3ds max will only set this ORT for Ease Curves. This only is used when mapping time to time. The slope will be set to one (a 45 degree diagonal starting at the end of the key range).
ORT_RELATIVE_REPEAT
This causes the key pattern to repeat with the first key taking off where the last key left off.
