When the CVs are active, choose Transform > Move and use the to move these CVs down the Z-axis to elongate the bottom of the sphere into a pointed shape.

Select the last row of CVs along the bottom of the second sphere.

Choose Pick > Nothing to ensure that no geometry is active.

When the CVs are active, choose Transform > Move and use the to move these CVs upwards along the Z-axis to elongate the top of the sphere into a pointed shape.

Choose Pick > Nothing to ensure that no geometry is active, then choose Pick > Point Types > CV and using the bounding box technique, select only the first row of CVs along the top of the second sphere.

Choose ObjectDisplay > Control and make sure the CVs is toggled ON (indicated by a check mark).

With the second sphere active, choose Transform > Scale and type 4 to scale the sphere to a value of 4 units.

When satisfied with the animation, you can delete the intermediate objects as their shapes are now recorded as keyframes. If you typed a keyframe time for the original shape, this is easily done by choosing Animation > Show > View Frame and typing the time of that keyframe. However, before deleting the animation, you may want to restore the original shape of the transforming object. When you complete the key shape animation, you can delete the animation and start again if you are not satisfied with the results. You can adjust this interpolation by modifying the tangents of the animation curves of the CVs in the Action Window. The interpolation between the CVs (the process that transforms one key shape into another) is, by default, a smooth interpolation. The key shape animation is created by animating each of the CVs of the original objects. If you want to keep the original geometry shapes, copy the original objects before invoking the function, or set a keyframe time for the original shape of the objects, so you can return the objects to their original shapes by viewing that keyframe time. This lets you position the object anywhere that is convenient. The location, in world space, of the slider geometry can be set here. When checked ON, geometry is created (a slider bar with the control’s name) and is attached to the control object so that the control range can be more easily identified. When checked OFF, the control object becomes a NULL DAG node, which can be picked from the SBD window. When checked ON, geometry is created (a small triangle) and is attached to the control object so that it can be more easily manipulated. When checked OFF, only the CVs that need to be transformed are added to the clusters, reducing the number of CVs being affected by the cluster. When checked ON, all CVs are added in the original object as a cluster, whether or not the CV will ever be affected by the ShapeShifter interpolation. The default setting is OFF, which allows “undershooting” and “overshooting” of the interpolation. When checked ON, the control object cannot be moved outside of this Control Range and has no effect on the ShapeShifter interpolation.

When the control object is positioned at the end point, the ShapeShifter interpolation has a 100% effect (the original object assumes the same shape as the target object).

When the control object is positioned at the start point, the ShapeShifter interpolation has a 0% effect (the original object is not interpolated towards the target shape).

These settings also control the placement of translation of the control object on the axis. The Control range settings determine the range of translation of the control object that affects the ShapeShifter interpolation.

X,Y,Z Translate – Moving the control object in the X, Y, or Z direction determines the amount of interpolation applied to the original object. Moving the control object in either of the other two axes has no effect on the ShapeShifter interpolation. The Control parameter options determine which translation direction of the control object will affect the ShapeShifter interpolation. Prompt – A prompt is displayed asking for the name of the control object.įrom target – The name of the control object is derived from the name of the target object. The control object is the object which when transformed using Transform > Move will cause the original object to change shape. The Control name options determine how the name of the control object is displayed.

When ShapeShifter Interpolation is selected, several additional options are displayed in the Set Keyshape Options window.
