In Magnetic mode, all points within the area around the mouse pointer move when the mouse button is clicked. Choosing this option exposes Magnet Distance and Magnet Strength controls to determine the size and falloff of the area. New points that enter the region during the move are ignored. In Region mode, all points within the area around the mouse pointer move when the mouse button is clicked. This mode is identical to normal polyline operation. When in Selected mode, adjustments to the grid are applied only to the currently selected points.
These three buttons determine the selection types used for manipulating the points. The selected button is highlighted to indicate that it is the currently active grid.Īll other controls in this tab affect the grid selected by this control. Only one grid can be displayed or manipulated at a time. The Source and Destination buttons determine whether the source grid or destination grid is currently active. The Controls tab contains parameters that configure the onscreen grid as well the type of distortion applied when a control point on the grid is moved. Using the Copy Src to Dest button, only the area modified by Grid Warp 2 is pasted as the foreground in the Merge. This can be useful for chaining the framing in a shot or adding slight movement to a still. An effects mask is applied to the tool after the tool is processed.īelow, two Grid Warp nodes are used to warp different areas of a frame. Connecting a mask to this input limits the warping to only those pixels within the mask. Effect Mask: The blue input is for a mask shape created by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools.Input: The orange input is used for the primary 2D image that is warped.The two inputs on the Grid Warp node are used to connect a 2D image and an effect mask, which can be used to limit the warped area. The image is deformed so that the source grid matches the destination grid. The Grid Warp node is a 2D deformation grid with flexible vertices.
