GLSL2

Here are some results from this project.

Feature implemented:

• Bump mapped terrain
• Rim lighting to simulate atmosphere
• Nighttime lights on the dark side of the globe
• Specular mapping
• Moving clouds
• water animation
• Space Screen Ambient Occlusion
• Vertex Morphing(Morphing between a sphere and the cow)(Press M/m button, N/n for pass shader)
• Vertex Pulsing(Press P/p button, N/n for pass shader)

Something is not normal about the vertex pulsing, although I move vertices along normals. I believe the reason is that a single vertex have many normals in the buffer, so when I move vertices, it have many directions. As a result, the cow becomes explosive.
