Specifying a Fixed Camera (existing 2.2 API)

 // Create a camera and add it to the Scene
Camera camera = new PerspectiveCamera();
scene.setCamera(camera);

Specifying a Movable Camera

 // Create a camera and add it to the Scene
Camera camera = new PerspectiveCamera();
scene.setCamera(camera);

// Add camera to scene graph (so it can move)
Group cameraGroup = new Group();
cameraGroup.getChildren().add(camera);
root.getChildren().add(cameraGroup);

// Rotate the camera
camera.rotate(45);

// Move the cameraGroup (camera moves with it)
cameraGroup.setTranslateZ(-75);

3D primitives

• Added two type of 3D shapes, extending from an abstract Shape3D base class:
  • User-defined shapes (MeshView)
  • Predefined shapes

User-defined shapes

•  User defined mesh (geometry) of a shape by specifying a set of points, texture coordinates, and faces (triangles that describe the topology)
•  User defined smoothing group to specify group of faces that are part of the same curved surface
•  A mesh is sharable among mutiple user-defined shapes

Predefined shapes

•  Three commonly used predefined 3D shapes are introduced: Box, Cylinder and Sphere
