X3D Example Archives: X3D for Web Authors, Chapter 11 - Lighting Environmental Effects

Lights illuminate geometry in a scene relative to the user's view. Lighting nodes include DirectionalLight, PointLight, SpotLight, and the active NavigationInfo headlight. Environmental effects include Background, TextureBackground, Fog and LocalFog. Lights, NavigationInfo, background nodes and fog nodes are each bound nodes, meaning that only one of each can be active at a time.

The supporting Chapter 11 slideset and course videos are available online via X3dGraphics.com.

X3D Scenes	Descriptions
Background Colors Only	Added a Background node to the KelpForest world.
Background Images Only	Simple Background node with images only.
Background Kelp Forest Main	Added a Background node to the KelpForest world.
Background Selector	Select one of four Background nodes to show a time-of-day effect.
Background Sequencer	Select one of four Background nodes to show a time-of-day effect.
Background Time Of Day	Interpolate between Background color arrays to show a gradually changing time-of-day effect.
Directional Light	An example of the DirectionalLight node showing no shadows on the lit geometry.
Fog - Kelp Forest Main	Added fog to the KelpForest world to simulate the typical weather pattern in June in Monterey, CA.
Point Light	Two examples of scoped PointLight nodes showing the effects of distance on lit geometry. Faceted IndexedFaceSet is on the left, simple Box on the right.
Point Light Color	Example of a PointLight node showing the effect of distance on lighting of geometry.
Spot Light	Example SpotLight node showing effects of beamWidth and cutOffAngle
Spot Light Color	Example of SpotLight showing effect of varying light colors on appearance
Spot Light Visualization	Create outline geometry to show SpotLight coverage. Author TODO: use the X3D-Edit SpotLight editor to modify and re-visualize the first SpotLight.
Texture Background - Kelp Forest Main	Added an image panorama with the Background node to the Kelp Forest world.
Texture Background	Simple TextureBackground node with images only.
