WebGL Lighting

Earth and Projector Light

Swipe to Spin Earth

Your browser doesn't support WebGL.

Display projector lighting with a light map and WebGL. Load two maps. One map textures the earth. The other map projects the image of an eye on the earth. Swipe to rotate the earth. The eye light map 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 a Photoshop wing ding and some 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.

Inspiration for the eye light map over the earth came from the following Scripture.

For the eyes of the LORD range throughout the earth to strengthen those whose hearts are fully committed to him...(2 Chronicles 16:9 NUV)
