- 3. JavaFX JavaFX is a graphical user interface (GUI) from Oracle. It provides lightweight , hardware-accelerated platform. As of version JDK 7 , it comes included with the Java install. 3

- 5. Overview JavaFX 3D graphics features currently available through the Java 8 APIs for JavaFX. The JavaFX 3D graphics APIs provide a general purpose three- dimensional graphics library for the JavaFX platform. We can use 3D geometry, cameras, and lights to create, display, and manipulate objects in 3D space. Some Samples of JavaFX 3D Graphics Use Case: 3D Charting Mechanical CAD Entertainment 5
- 6. 3D Shapes A point in 3D space is represented as (x,y,z). The dimensions identify the width , height and depth. X Z Y To check to see if your computer supports 3D graphics, you can use this statement in Java : System.out.println(Platform.isSupported(C onditionalFeature.SCENE3D)); 6
- 7. nodes are rendered in the order that they're added to the scene graph. For the correct order, we can specify that the scene needs a depth buffer. For example : boolean depthBuffer = true; Scene scene = new Scene(root,300,300, depthBuffer); To view shapes with a Z value, a camera must be added. 3D Shapes 7
- 8. All shapes have a material, draw mode, and cull face. Material gives shapes color. Draw mode indicates how the shape is rendered. face culling is a technique used to only render the visible portions of your 3D image. 3D Shapes 8
- 9. All shapes are made up of triangles. A box has 12 triangles. Shapes are nodes ,so we can apply transformations. They can be positioned at any point using the translateX, translateY,and translateZ transformations. 3D Shapes 9

- 11. To create 3D shapes, we use a triangle mesh. JavaFX has a MeshView class to represents user-defined 3D shapes. A triangle mesh needs data for three aspects of a 3D object : texture coordinates, points and faces. User-Defined Shapes 11
- 12. The texture is an image is of a 2D object mapped to the vertices of the triangles. Points are the vertices of the triangles in the mesh. faces are the planes created by joining these vertices. User-Defined Shapes PyramidExample.java 12
- 13. By default, the scene is a 2D image. To view third dimension, you add a camera. the camera coordinate system is as follows: x-axis is pointing to the right. y-axis is pointing down. z-axis points away from the viewer Add Camera 13
- 14. The camera sets the viewing perspective of having a third dimension. A camera is a node in JavaFX. When adding a camera, we can specify clipping panes. Add Camera Shapes3D_with_camera.java CameraExample.java 14
- 15. Add Lighting Light is also a node in Java FX. Ambient and point light represent light from external source. Each light node can a different color. Ambient Light is a non-directional light. Point Light represents appoint light source. This is a fixed point in space and radiates light equally in all direction. The intensity decreases as the distance increases. Shapes3D_with_light.java 15
- 16. Shape materials Shading material mixes light, color, and shade . This gives the illusion of a 3D effect. A special type of shading material called Phong. Phong shading is a technique used to render 3D objects. MaterialDemo.java 16
