I'm using this algorithim to move the camera fowards:

switch(event.key.keysym.sym)
	{
	case SDLK_w:
	 Vector tmp;
	 tmp.x = view.x - main.x;
	 tmp.y = view.y - main.y;
	 tmp.z = view.z - main.z;
	 view.x = tmp.x + view.x;
	 view.z = tmp.z + view.z;
	 main.x = tmp.x + main.x;
	 main.z = tmp.z + main.z;
	 break;

I tried adding * -1 to the end of Lines 8-11, but I didn't work, how can I get the camera to move backwards?

You just have to multiply the amount that you're moving by -1. It looks like your tmp vector is the amount of the movement? Multiply tmp by -1. You may even want to normalize it first, so the camera always moves by 1 unit, making it a smooth movement. You can then scale the vector to move the camera faster or slower.

Hope this helps.
