3D Level Test

@ Antony,

I am using mipmapping (I tried it without and it looks craptastic!). But the filter type is just normal point linear so maybe that's it?

glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR_MIPMAP_LINEAR);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
