    Inheritance diagram for CTrack:

    Detailed Description

    Represents an animation track.
    Contains curves holding keys.
    Example: Creating Align to Spline tag and adding track with 2 keys:

    // Add align to spline tag to object
    BaseTag* tag = op->MakeTag(Taligntospline);
    if (tag)
    {
    // Allocate track for align to spline tag
    if (track)
    {
    // Add track to align to spline tag
    tag->InsertTrackSorted(track);
    // Get track curve
    CCurve* curve = track->GetCurve();
    if (curve!=nullptr)
    {
    // Add first key
    CKey* key = curve->AddKey(BaseTime(0.0));
    key->SetValue(curve, 0.0);
    // Add second key
    key = curve->AddKey(BaseTime(1.0));
    key->SetValue(curve, 0.9);
    }
    }
    }
