I believe the following will do what you want, though banister's suggestion to use coerce instead of monkey-patching Numeric is a preferred method. Use this method only if necessary (for example if you only want some binary operands to be transitive).

Fixnum.class_eval do
  original_times = instance_method(:*)
  define_method(:*) do |other|
    if other.kind_of?(Vec3)
      return other * self
    else
      return original_times.bind(self).call(other)
    end
  end
end
