    This:

    struct Vec3* v = malloc(sizeof(struct Vec3));

    is better written as:

    struct Vec3 * const v = malloc(sizeof *v);

I don't love this. Other people are going to think you're only allocating a pointer. It's potentially confusing.

I also personally find totally confusing leaving the * in the middle of nowhere, like flapping in the breeze.

Uh, okay, but if you need to constantly write code as if people reading it don't understand the language, then ... I don't know how to do that. :)

It's not possible to know C code and think that

    sizeof *v

and

    sizeof v

somehow mean the same thing, at least not to me.
