Socoder -> C/C++/C#/Other -> VBO/IBO Terrain Rendering Problem

 		Hello, I am having a heck of a time getting my head around vbo/ibo fully.
Right now my terrain is rendering wrong..it is rendering with two layers..when it should only have one.



The diagonal solid strips aren't supposed to be there...only the triangles. This is causing me problems because it makes it so that the terrain appears to have two layers in some parts.

For example here is two screenshots of me inside of the terrain.

Here is a pastebin of how I create and draw my terrain.

Normally, I render my terrain with GL_TRIANGLE_STRIP. I am only using GL_TRIANGLES at the moment so that I can see what is going on easier.

Any help would be hugely appreciated..this has been bugging me for a while.

Thanks.

 		From the second screenshot, it looks like the last row of triangles is connected to the first row, so they span the entire terrain. Maybe they are connected to (0,0,0), caused by references to empty vertices in the triangles?
