for loop concatenation for 300 billboarding trees

[farshizzo]

Hi Eugene,

I tried your file and billboarding worked automatically. Which version of Vizard are you running? The latest version is 2.15b, you might want to upgrade if you have an older version. Our vrml loader doesn't support sound, but I will go ahead and try to include that. In the meantime you could use the following code to play 3d sounds in your world:

#Create an invisible object that will play the sound
obj = viz.add(viz.GROUP)

#Place the object where we want the sound to come from
obj.translate(5,0,7)

#Loop a sound eminating from the objects location
obj.playsound('sound.wav',viz.LOOP)

Also, use the following code to add fog to your world:

#Set the fog color to white
viz.fogcolor(1,1,1)

#This will create exponential fog
viz.fog(0.1)

#This will create linear fog
viz.fog(5,20)

Good luck!
