3 Adjust the manipulators to modify the surface.
TIP You can also select a bilinear surface by opening the Group Schematic.
Using Parenting Axes
You can add axes to a 3D scene and parent them to cameras, lights, layers,
and other axes in the Group Schematic. This lets you control the movement
of one or more child objects by transforming the parent axis.
You can transform axes interactively using the transformation buttons in the
Axes tab, where you can also set values for the axis position, rotation, scale,
and pivot. You can animate and set expressions for all transformation values,
as well as assign them to a tracker. The axis is represented by a white cross in
the Player, which you can select and interactively move with the manipulator.
NOTE The axis icon is visible only if you have selected Icons in the Render tab of
Reaction.
To add an axis from the Axes tab:
1 In the Schematic view, select the Reaction node and then select the Axes
tab.
2 From the Axes list, click Add.
An axis is added to the Axes list.
3 In the Schematic view, double-click the Reaction node to display the
Group Schematic.
4 Parent the axis to a layer, camera, or light.
