VRET Vizard

Getting Started

Vizard has a very nice tutorial and help file that is also available online on the Vizard website. It explains the basics of Vizard and also if needed the basics of Python the language used to control Vizard.

Resources

Vizard comes with a few build in object like avatars and a duck but you most likely want to add your own objects too your program. To avoid having to use absolute paths you can add your directory to the path list of Vizard so that you can reffere to the object directly.

viz.res.addPath(<'directory') example: viz.res.addPath('G:\Vizard projects')

you can also reffere to the directory where the main (running) .py file is located by adding the line

viz.res.addPath('\\\\')

You can also reffere to objects in subdirectory's of the path directory's you added. example:

viz.add('Avatars\Male\casual09_m_highpoly.cfg')

HMD

With just a few lines of code Vizard can easily work with an HMD. All you need to add/replace from your code to get a image on the HMD are:

viz.displaymode(800,600,32,60) <viz.displaymode(width-screen,heigh-screen,color depth,refresh rate)>

viz.go(viz.QUAD_BUFFER |viz.FULLSCREEN) <replace the viz.go() with this>

Trackers

emagin

To get Vizard to accept input from the eMagin tracker (integrated in the HMD) you need to add the tracker as a sensor in Vizard and then link the sensor to the mainView-point

sensor = viztracker.add('emagin.dls')

viz.link(sensor,viz.MainView)

Don't forget to disable the eMagin mouse drivers if these are enabled in the "Control Panel>System>Hardware>Device Manager" list
