12. If you wish, you can set additional key frames to refine the camera path. Hold down
Ctrl+Alt or Command+Option and click on the z-axis curve in the Curve Editor, to add
new points to the curve, and then adjust their positions.
13. Before you continue, click the Node Graph tab to hide the Curve Editor and return to the
node trees.
14. Close all the control panels that are currently open.
Working with Geometry
In the previous example, you worked with the card object. Nuke also includes primitive geometry, which can be used as set-extension geometry or placeholders for other elements you
plan to add to scene.
To add primitive objects to the scene:
1. In the “3Dinteg_tutor.nk” project file, locate the node tree labelled “Working with Geometry.”
We’ve already supplied the 3D node tree with a camera for you, so you need to add the
geometry objects, and also create a “scene” where they can coexist.
2. Right-click over the node graph and choose 3D > Scene. Connect the Scene2 node to the
ScanlineRenderG node.
3. Connect a Viewer to the ScanlineRenderG node and switch to the 3D perspective view.
4. Right-click and choose 3D > Geometry > Cube.
The default cube primitive appears at the centre of the 3D workspace. Let’s reduce the
number of subdivisions on the cube.
