Detailed Description

The HKeyframeChannelFollowPath class is used for interpolators that change orientation in relation to position.

By specifying a set of positional control points, this interpolator can adjust the orientation of the target according to the path curvature like a car following the road.


Constructor & Destructor Documentation

HKeyframeChannelFollowPath::HKeyframeChannelFollowPath (  )  [inline]

Constructs a HKeyframeChannelFollowPath object.

Member Function Documentation

virtual HKeyframe* HKeyframeChannelFollowPath::Clone (  )  [inline, virtual]

This method makes an exact copy of the current HKeyframeChannelFollowPath and returns a pointer to the newly created HKeyframeChannelFollowPath object.

Returns:
A pointer to newly created HKeyframeChannelFollowPath object.

Reimplemented from HKeyframeChannelCurve.

virtual void HKeyframeChannelFollowPath::Interpolate ( HKeyframeChannel **  posarray,
int  keyframe,
float  fraction,
int  length,
HPoint res 
) [virtual]

Calculates the interpolation between this keyframe and the next keyframe.

Parameters:
posarray The array of HKeyframeChannel objects.
keyframe They current keyframe number.
fraction The fraction from this keyframe to next.
length The number of entries in the keyframe array.
res Returns the interpolation result.

Reimplemented from HKeyframeChannelCurve.

virtual void HKeyframeChannelFollowPath::Serialize ( HUtilityXMLTag *  xmlgen  )  [virtual]

Writes XML data to a buffer.

Reimplemented from HKeyframeChannelCurve.
