void BKE_fcurve_correct_bezpart	(	const float	v1[2],

	)

The length of each handle is not allowed to be more than the horizontal distance between (v1-v4). This is to prevent curve loops.

This function is very similar to BKE_curve_correct_bezpart(), but allows a steeper tangent for more snappy animations. This is not desired for other areas in which curves are used, though.

interval

Set to 1.0 to round to whole keyframes, 0.5 for in-between key-frames, etc.

Note

An interval of zero could be supported (this implies no rounding at all), however this risks very small differences in float values being treated as separate keyframes.

float evaluate_time_fmodifiers	(	FModifiersStackStorage *	storage,

	)

Evaluate time modifications imposed by some F-Curve Modifiers.

• This step acts as an optimization to prevent the F-Curve stack being evaluated several times by modifiers requesting the time be modified, as the final result would have required using the modified time
• Modifiers only ever receive the unmodified time, as subsequent modifiers should be working on the 'global' result of the modified curve, not some localized segment, so evaltime gets set to whatever the last time-modifying modifier likes.
• We start from the end of the stack, as only the last one matters for now.

Parameters

fcu	Can be NULL.
