Dont know what the problem is but I have objects in my world that are all transformed correctly but when I come to adding a camera transform it doesnt seem to work. I have a matrix which should be the current camera transform but do I have to multiply that by each object? Or is there a function which sets the current view matrix? A little stuck.

In OpenGL, the world and view matrices are combined into the modelview matrix. Load your camera transform matrix into OpenGL's modelview matrix before you start rendering, push it on to the matrix stack when you're doing local object transformations, then pop it off to render the next object...
