示例1: reverse
CatmullRomBy* CatmullRomBy::reverse() const
{
PointArray *copyConfig = _points->clone();
//
// convert "absolutes" to "diffs"
//
Vector2 p = copyConfig->getControlPointAtIndex(0);
for (ssize_t i = 1; i < copyConfig->count(); ++i)
{
Vector2 current = copyConfig->getControlPointAtIndex(i);
Vector2 diff = current - p;
copyConfig->replaceControlPoint(diff, i);
p = current;
}
// convert to "diffs" to "reverse absolute"
PointArray *reverse = copyConfig->reverse();
// 1st element (which should be 0,0) should be here too
