Creating and Modifying Shapes
Many of the shape controls of the Warper and Morpher nodes are identical to those of
the RotoShape node, and all share the same methods for creating tangents, closing
shapes, inserting and deleting points, and so on. If necessary, you can refer to the
RotoShape documentation for more information on creating and modifying shapes.
Warper and Morpher Viewer Shelf Controls
When a Warper or Morpher node is selected, the following buttons appear in the
Viewer shelf.
.
Button Description
Add Shapes Creates new shapes. Closed shapes are created by
clicking the first shape point you created. Open
shapes and single-point shapes are created by
double-clicking when creating the last point, or by
right-clicking in the Viewer, then choosing Finish
Shape from the shortcut menu.
Edit Shapes Allows you to edit shapes.
Connect Shapes Clicking this button allows you to create a source/
target shape pair by first clicking the shape you
want to be the source, and then clicking a second
time the target shape you want to link it to.
To define a boundary shape, click this button, then
click twice a shape you want to turn into a boundary
shape. This effectively makes a single shape into
both a source and target shape.
Edit Connections Once two shapes have been joined with the
Connect Shapes button, the location and angle of
each connection line that links source to target
shapes may be edited by clicking this button. With
this control turned on, select the source or
destination point of a connection line.
Show/Hide Tangents Toggles the Viewer among showing All shape
tangents (the handles that allow you to manipulate
Bezier curves), None, or Pick, which only shows the
shape tangents of individually selected points.
Lock/Unlock Tangents Locks or unlocks all shape tangents in the Viewer. If
locked, shape points may still be moved, but the
tangents defining the angle of curvature remain
locked.
