JavaFX: Lighting

The lighting effect simulates a light source shining on the given content, which can be used to give flat objects a more realistic three-dimensional appearance.

 

Why lighting?

Makes scenes look like 3D.

 

Light class

Light class is an abstract base class for all light implementations.

 

Different types of Light implementations

JavaFX support 3 different types of lights.

a.   Distant light (Light.Distant)

b.   Point light (Light.Point) 

c. Spot light (Light.Spot)

 

Lighting class

Lighting an effect that simulates a light source shining on the given content, which can be used to give flat objects a more realistic, three-dimensional appearance.

 

You need to create a Lighting instance with specific Light instance and apply Lighting effect a node.

 

Example

Light.Distant distantLight = new Light.Distant();

distantLight.setAzimuth(160);

 

Lighting lighting = new Lighting(distantLight);

lighting.setSurfaceScale(10);

 

text1.setEffect(lighting);
