EarthScape is an experiment with shader effects by Tyler Wood and me.

We were tasked with applying multiple shader effects to a scene of a sphere(earth) with a smaller sphere(moon) orbiting around it. We used shaders to apply post processing effects, textures and normal maps to the spheres, make a billboard sun, and animate the oceans, clouds, and stars. 

The post processing effects we implemented were God rays, lighting, texture blending, shadows, and blur. All of the effects have values that can be changed while the scene is running in order to emphasize a certain effect. A few of the effects can be seen in the gifs above.
