Idea cheap cloud gaming for webgl:

on server side you got a browser web running the game

On this server you take regular screenshot .toDataUrl

You send them to the player device... mobile phone, tablette whatever.

Thus the player can see webgl rendering on any device.

The player use touch screen as inputs

They are then sent to the server which send them back to the browser.

So we got the whole loop. The browser receives inputs from the player.

And the player sees what is displayed in the browser.

this is actual cloud gaming! All that with a simple node.js server to write and some js code. Maybe a few days. Surely less than a week.

Performances are left as an exercice to the reader :)

sounds - raw via webaudio api

• taken with web audio api
• sent to server which echo it to player's device
• they are reassembled and played

sounds - webrtc

• use webrtc to send the sound from the browser
• likely much more efficient than websocket version
• require player's device to support webrtc

remote controler capability

• it all depends on the capability of the remote controler
• there is the screen, the speakers, and the inputs, such as keyboard, mouse, touch screen
• webgl canvas are sent as image. This one seems obvious.
• the remote player inputs is less obvious.
  • it depends on the input of the game itself
  • this page is not in three.xcloudgaming

software architechture

• a controls for three.js something generic for people to try
• joystick + fire on remote controllers
• simple node.js in between. Just echo the message from one to the other
• inputs are just echoed
• images are just echoed

improvements

• if all position are precomputed, webgl isnt required on server
  • may go up to fully running in node.js
• depending on remote controller capability, some parts may be displayed dynamically
• it is all a balance
