# `Cauldron3D.Net.Channel`
[🔗](https://github.com/jaman/cauldron/blob/v0.3.3/cauldron_3d_net/lib/cauldron_3d/net/channel.ex#L1)

The Phoenix channel a browser joins to watch a `Cauldron3D.Net.Scene`.

    defmodule MyGame.Web.SceneChannel do
      use Cauldron3D.Net.Channel
    end

The topic is `"scene:<id>"` (`:topic` names another prefix), `id` a scene started with
`Cauldron3D.Net.Scene.start_link/1`. On joining, the browser is pushed the whole scene
as one binary `"changes"` message, then each batch the scene broadcasts; its `"event"`
messages reach the scene's `:events` pid (`Cauldron3D.Net.Events`), with `:joined` when
it arrives and `:left` when it goes.
