You won't be able to create an embedded 3D scene with a Torus using JavaFX 2.x without a lot of custom coding on your part. However this becomes easy if you use JavaFX 8 and the third party 3D library F(X)yz: http://birdasaur.github.io/FXyz/

F(X)yz has a Torus object:

/src/org/fxyz/shapes/Torus.java

You can see how to use it with the provided test code:

/src/org/fxyz/tests/TorusTest.java

Part of your question was how to place the 3D object into your existing JavaFX scene using the Split Pane. The Split Pane doesn't care if its content is 3D but you should use a SubScene to embed the 3D content into the 3D scene.

Example:

SubScene subScene = subScene = new SubScene(sceneRoot, sceneWidth, sceneHeight, true, SceneAntialiasing.BALANCED);
subScene.setFill(Color.STEELBLUE);
Camera 3DCamera = new PerspectiveCamera(true); 
3Dcamera.setNearClip(0.1);
3Dcamera.setFarClip(100000.0);
3Dcamera.setFieldOfView(35);
3Dcamera.setTranslateZ(cameraDistance);
subScene.setCamera(3Dcamera);
//Add the subscene to the SplitPane
mySplitPane.getChildren().add(subScene);

Good luck.
