Threex reorga

[jeromeetienne]

• what needs to be done
• how to document the project
• which code needs to be written
  • write minigame and put repetitive code in threex module
• support modern web practices
  • support for bower, require.js, yeoman
  • support them but don't depends on them
  • all optional
• all independant modules not a big framework

[jeromeetienne]

@erichlof im starting here :)

[jeromeetienne]

modules category

• in order to easily retrieve modules they will be tagged
• if possible similar modules should have similar api
• content, posteffect, inputs, tools

[jeromeetienne]

possible minigame

• pong3d as you did a pong too
  • http://jeromeetienne.github.io/pongGL/
• mmo3d
  • http://mmo3d.jit.su
• marbletable
  • http://jeromeetienne.github.io/marbletable2/
• @erichlof comes plug yours here :)

[jeromeetienne]

particles

• good stuff in threex.particles
• yet to be documented
• how to expose that at the package level

[jeromeetienne]

what to do for collision physics

• full blast one? Cannon.js ? Ammo.js ?
  • maturity of those library ?
  • hpw maintained they are?
• something simple ala babylon.js?
• something based on old collision.js from r40
• when to do that ?
  • can we wait? Is that the most urgent now

[jeromeetienne]

sound

• web audio api seems the way to go as it is availble where webgl is available
• webaudio.js? For the lib ala tquery
• webaudiox? For the lib ala threex
• howler.js?

Likely webaudiox as it provide sound localisation so important in 3d. It is already documented, which cant hurt

[jeromeetienne]

menu and ui with normal DOM

• like in marbleTable

[jeromeetienne]

documentation

• written in markdown for simplicty and portability
  • they can be seen directly in github, or in blogs,
  • using http://strapdownjs.com/ for now. it is simple and works now. thus we can focus on content
  • see http://jeromeetienne.github.io/threex/www/how-to-write-a-threex-module.html
• http://passportjs.org/guide/ is great! clear and simple. copy it ?
  • find it here https://github.com/jaredhanson/www.passportjs.org/tree/master/content/guide
• like "how to write a threex module"
• some describe "how to do that" like how read keyboard, or how to get device orientation
• some describe study case,
  • like to do this mingame,
  • take thoses modules and add this gameplay on top,
  • where to get the assets

[jeromeetienne]

inspiration

• be the unity of the Web?
• babylon js is young but got nice game orientation and nice tutorials
• recognize what they do well and improve yourself

[jeromeetienne]

user identification

• passport.js to link with social network identity

[erichlof]

possible minigames

• pong3d as you did a pong too
  • http://jeromeetienne.github.io/pongGL/
• mmo3d
  • http://mmo3d.jit.su
• marbletable
  • http://jeromeetienne.github.io/marbletable2/
• SpacePong3D
  • Would show how to get a simple game up and running with some ThreeX helpers

• WebAsteroids
  • Would demonstrate third-person camera above the ship, as well as 2D sprite explosions/threex laser effects
    
• 3DLightCycles
  • Tron Lightcycle clone that could demonstrate Jerome's threex.geometricglow effect, like in the Tron movies

• 3DArtilleryWars
  • Would be the most advanced tutorial game showing Cannon ballistic physics engine (if terrain is one day supported)

All of these games I wrote back in 1998-2000 and I still have the C code for! :) Some may be a bit too ambitious but all of them would show something different about ThreeX. For instance all of them will require:

• threex transparency (on most games)
• threex geometric glow (for tron game)
• threex glow keycolor (possibly for tron game)
• threex window-resize (all games)
• threex virtual joystick (all games)
• threex keyboard state (all games)
• threex laser (for the space games)
• threex dynamic texture (for 'scores' and 'lives left' text)
• threex grass ground (for artillery game)
• threex cannonjs (for artillery game)
• threex mountains arena (possibly for artillery game's terrain)
• threex skymap (for pong game and artillery game)
• threex depth of field (possibly)
• threex volumetric spotlight (I have another idea for a game that needs this but is not pictured here)

Hi Jerome,
Sorry I have been absent for a while. I have been in deep working on integrating JigLibjs2 (a light but robust javascript physics engine) with three.min.js . JigLibjs2 supports terrain (or heightfield mesh) collision detection out of the box. I am happy to report that everything seems to work so far, and I have a simple working demo (with a car and some shapes)! I will open up a new repo for this effort. Maybe a future 'THREEx.Physics' plugin could wrap up some of the set-up code?

I also have a mini-game idea to use threex.poolball and threex.laser! :)
Stay tuned!

-Erich

[jeromeetienne]

seems greats! i cant wait to hear about your laser pool :)

Sure we should provide extensions of realistic physics. i already started
with threex.cannonjs http://jeromeetienne.github.io/threex/#threex.cannonjs

url on the demo ? i tried jiglib2 a while back and i found it buggy.. for
sure unable to do car kind of stuff, but i would be delighted to be wrong :)

Hi, here's the idea for laser-pool, using your THREEx.poolball:
First, a little backstory...
I am a billiards fan - both American pool, and 3-cushion carom billiards (without pockets). There are already many games such as the Celeris Virtual Pool series, VRCarom, Carom3D and even a recent Google Chrome demo using the webaudio API: http://chromium.googlecode.com/svn/trunk/samples/audio/o3d-webgl-samples/pool.html

Since the classic games and realistic physics have already been done many times (and there is no way to compete with these great implementations), I thought why not do something different with the basic game setting and mechanics? How about we stretch the 2D flat pool-table to a 3D cube?! Of course, with gravity, the balls would all fall down to the bottom of the cube, but...

Setting is in outer-space, maybe aboard a spaceship ( a gameroom, like in StarWars chess ) with 0-gravity, or just floating in outer-space - either way, no gravity! The pool-table is now a 3D cube, and your camera is positioned behind the white cueball. But, with the help of three.js Orbit controls, you can now move your aim anywhere around you! The pockets are still in the corners, although now there are 8 or more pockets, to ease the shot-making in 3D.

Ball collisions and impulse responses are handled through whatever physics engine we can get working. It is already possible with threex.cannonjs sphere objects, but I will see if it's also possible in JigLibJS2 that I have been working on.

Next problem would be friction. In real world mechanics, friction of the table-cloth slows the balls down so you can make the next shot. But in space they just keep bouncing forever, right? Well, here comes THREEx.laser! I was thinking we emit a pulse laser, red or blue, and quickly pulse the ball from the opposite direction that it is traveling. The pulses get faster and faster and slow the ball down to 0. Essentially, friction in Space! Thus, at the end of each shot, the balls just hang there, motionless - kind of cool.

Also, we could use THREEx.laser to aim your cueball, kind of like a laser-sight on a sniper rifle. The laser aim-helper could also bounce off the walls of the cube, showing a possible bank shot opportunity. For easing the math, Three.js added a vector.reflect function to their Vector3 class, at my request almost a year ago.

So far as ball rotational forces go, the space environment pretty much eliminates the need for this functionality, which eases our project somewhat. I guess they could keep spinning in mid-air, but they should eventually stop also, so you can see the great number-texture that Jerome has applied to each poolball. :)

Background can be a skybox of space, or a ship with a 0-G room, and maybe a window out into space. This is sort of the StarWars or StarTrek version of billiards in the future (or in the past with StarWars - haha). :)

Let me know what you think.

i love the idea!

i would love to have a reliable physics layer. i watched the demo with the
car :)
