3D Earth with Light Map

Swipe to Spin Earth

Your browser doesn't support WebGL.

Display lighting with a light map and WebGL. Load two maps. One map textures the earth. The other map provides lighting. Swipe to rotate the earth. Cloudy lighting doesn't move as the earth rotates.

Light maps provide a quick and uncomplicated method to display lighting. Simply load a different light map to change the lighting.

The image for the light map was generated with Photoshop gradations, blur, and filters.

The image for the texture map was applied to a sphere. NASA generated the original earth map. Seven Thunder Software modified the texture map with Photoshop.

See other WebGL lighting examples for the e-book WebGL Lighting. See free WebGL light techniques.
