Question: references and code style about cgmath HOT 5 CLOSED

Let me try. look_at doesn't really need the values directly, it just performs calculations based on the vectors you provide. Frustum::new on the other hand uses the given set of planes directly to store it. I do realize, however, that this is an implementation detail, so maybe we shouldn't reflect that in the interface.

Ok, so your general preference is to pass in stuff by reference to avoid copies then? I might be contributing with other minor pieces of code these days, so I'm trying to understand your coding guidelines. This is also my third day of Rust, so I am also using your library as a source of inspiration :)

Yes, that was my impression. I'm not the best person to answer that though, so please wait for @bjz to get here.

For constructors I normally go by value, but for methods by ref. This may or may not be the best way... I dunno.

We are now moving to a by-value style - see #247
