Code Assist, OpenGL VAO/VBO Classes not drawing?

Vertex is a vector. Taking its address will not give you a pointer to the data.

That iBound member of VBO looks suspicious. The OpenGL binding state may change, for example after switching the bound VAO, but the VBO class instance still thinks it's active. Just drop iBound altogether and re-bind every time you need the object.

With modern drivers rebinding an already bound object is almost for free.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
