Head Height

[Gladsomebeast]

Here is the proper way to setup PPT and Intersense head tracking in Vizard 3.0. If you are not using Vizard 3.0, download it.

import viz
viz.go()

PORT_PPT = 0 #Com port number. Zero to search through COM1 to COM4
headPosSensor = viz.add('vizppt.dls')
PORT_INTERSENSE = 0 #Com port number. Zero to search through COM1 to COM4
headOriSensor = viz.add('intersense.dls')
headCombined = viz.mergeLinkable( headPosSensor, headOriSensor )

# Link hybrid head sensor to view and don't offset by eyeheight
headLink = viz.link(headCombined, viz.MainView, dstFlag = viz.LINK_POS_RAW)

#add world
viz.add('court.ive')

Simplicity is a virtue. This works for me.

from viz import *

go()

room = add('gallery.ive')

pos = add('vizppt.dls')
ori = add('intersense.dls')
tracker()

def onKeyDown(key):
	
	if key == 'r':
		pos.reset()
		ori.reset()
		
	if key == '1':
		eyeheight(1.8)
	if key == '2':
		eyeheight(0)
	if key == '3':
		eyeheight(4)
		
callback(KEYDOWN_EVENT,onKeyDown)

Initially the eyeheight comes out too high for some reason, but if
you hit 'r' it makes it 1.8m. Also, you can change the eyeheight to
whatever you want using the viz.eyeheight(height) command.
After that hitting 'r' will reset the eyeheight to whatever 'height' is.
