示例1: Update

bool MorphController::Update (double applicationTime)

// interpolation, you need to provide a more sophisticated key (Bezier
// cubic or TCB spline, for example).
if (!Controller::Update(applicationTime))
{
return false;
}
// Get access to the vertex buffer to store the blended targets.
Visual* visual = StaticCast<Visual>(mObject);
