Perhaps is it a good idea to declare, Ship dimensions for various ship types.
External slots should be dimensioned to.
I know, thats in this phase on 3D battle developing isn't possible, to declare triangles and textures limits for each model type.
With 5000-10000 triangles and normal maps is it possible to make impressive looking 3D models.
It's not clear what you are asking -- for the theoretical physical dimensions of the ships? I don't see how it matters, they are unlikely to be set next to anything of know size.
