[Papervision3D] 3D Sound Experiment

[De'Angelo Richardson]

Thanks. Yea, I was wondering where to put it. So far it's 2 separate functions add3DSound( URL, Obj); added to init3D(); and updateSound(Obj); added to the loop3D section.
   
  here's the code.
   
  function add3DSound (soundObj, Obj){
   sound = Obj.sound
   sound = new Sound();
   sound.loadSound(soundObj,true);
   updateSound3D(Obj);
  }
function updateSound3D (Obj){
   newX = int(Obj.x-camera.x);
   newY = int(Obj.y-camera.y);
   newZ = int(Obj.z-camera.z);
   maxSdist = 1050
   Sdist = Math.sqrt(newX*newX+newY*newY+newZ*newZ);
   SndAngle = int(Math.atan(newX/newZ)*180/Math.PI) - camera.rotationY;
  
  
   Sound3D = SndAngle;
   if (Sound3D>359){
    Sound3D = (Sound3D%360);
    
   } else if(Sound3D<=0){
    Sound3D = 360+(Sound3D%360);
   }
   if (newZ<0){
    Sound3D = ((Sound3D)+180)%360;
   } else if(newZ>0){
    Sound3D = Sound3D;
   }//*/
   if(Sdist<=maxSdist){
    Sound3Ddist = Math.abs((Sdist/maxSdist)-1)*100;
   } else {
    Sound3Ddist = 0;
   }
   S3Dang = (Sound3D - 180);
   Panner = (S3Dang - 180)/180;
   if(S3Dang>=-180 and S3Dang<=0){
    S3Dang += 180;
    Panner = int(S3Dang/90*100);
   } else if (S3Dang<179 and S3Dang>0){
    S3Dang -= 179;
    Panner = int(S3Dang/90*100);
   }
   if(Panner<-100){
    Panner = -(Panner%100 + 99)
   }else if(Panner>100){
    Panner = 99 - (Panner%100)
   }else if(Panner == 200 or Panner == -200){
    Panner = 0
   }
   sound.setVolume(int(Sound3Ddist));
   sound.setPan(Panner);
  }

  This is so cool. Can't stop playing with it!

I haven't thought of 3d sound before, but it's such a nice touch. It makes the whole thing much more immersive.

Maybe we could have a sound:Sound property on each DisplayObject3D so the volume/balance would be adjusted on every render. 

Most per object calculations are affordable performance wise, so there shouldn't be any speed penalty.

It'll be brilliant for PaperWorld.

Excellent work De'Angelo.
