Interactive demo of JavaFX Lighting effect of Light.Distant

• javafx.scene.effect.Lighting is 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.
• javafx.scene.effect.Light.Distant represents a distant light source
