Update - normals, heightmaps, etc.

Been a busy couple of weeks so slow updates.

Trying to improve the lighting.. doing the normals was a bit tricky but this was ultimately very helpful.  Now mountains look more realistic due to the lighting.

I'm technically not following the stanford curriculum anymore.. I just wanna make this one image as cool as I can so I wanna eventually add in water and fog in the background, after I get the normals working right for the mountains.

BOOM SON

My thing worked!

Perlin noise used here: I have an image of Perlin Noise and loaded that as a texture.  Then in the vertex shader I did the texture map thing, got the x value, and set the height to that.  So it's not terribly complicated but it look really cool, especially when it's rotated around.  I really wish I had screen capture software but I'm paranoid to download things off the internet now after what happened last time.

Contemplating whether I wanna add water or just leave it as is.
