Detailed DescriptionThe Q3CanvasSpline class provides multi-bezier splines on a Q3Canvas. A Q3CanvasSpline is a sequence of 4-point bezier curves joined together to make a curved shape. You set the control points of the spline with setControlPoints(). If the bezier is closed(), then the first control point will be re-used as the last control point. Therefore, a closed bezier must have a multiple of 3 control points and an open bezier must have one extra point. The beziers are not necessarily joined "smoothly". To ensure this, set control points appropriately (general reference texts about beziers will explain this in detail). Like any other canvas item splines can be moved with Q3CanvasItem::move() and Q3CanvasItem::moveBy(), or by setting coordinates with Q3CanvasItem::setX(), Q3CanvasItem::setY() and Q3CanvasItem::setZ().
