PPT causing height problem

[just alex]

For some reason, whenever I have my PPT computer connected and active with my rendering computer, the default viewpoint becomes 2 or 3 times higher than a person should be. When I run the program without PPT going, the point of view spawns at a normal height. I'm wondering if it's a problem with my code (I got thrown headfirst into this level of programming)

#adds the ppt

ppt = viz.add('vizppt.dls')

ppt.command(3,"",1,1,5) #scales ppt tracking on xyz axis


#collisions on
viz.collision(viz.ON)
view = viz.get(viz.MAIN_VIEWPOINT)
view.rotate(0,1,0,90)

#gonna comment out the collision for now, it's registering when the avatar touches
#ground as a collision

#This function is called when a collision occurs
def mycollision(info):
print 'Collided'


#Create a callback for a collision event
viz.callback(viz.COLLISION_EVENT, mycollision)

As an aside, there's an extra female model spawning across the "street" from the spawn point and I can't figure out where the heck she's coming from. If anyone notices before I can find it, I'd appreciate it

Try adding the following line to your script:viz.eyeheight(0)The default eye height is 1.8 meters, and it will be added to the Y position of your tracker. Setting it to 0 will simply apply the raw tracking data to the viewpoint height.

Thanks, that fixed everything up for me.
And I found where the random extra avatar was coming from.
