Hi,
Thanks for giving me some time to introspect into the problem!
I have solved this problem of mine! For future reference of people who might fall in the same pit, I read this thread -
http://forum.worldviz.com/showthread.php?t=1588, which discussed the exact same problem.
Aside from correcting the corner coordinates of the Vizwall, I also figured that for making a CAVE-style head-tracking, I will need to either mask the headlink with something like headLink.setMask(viz.LINK_POS), or use the CaveView class, which does similar stuff.
I also fixed the lighting problem thus:
Code:
mylight = viz.add(viz.LIGHT)
mylight.position(1.5, 1.5, 0.5)
mylight.direction(1.5, 1.5, -10.0)
mylight.spread(180)
Also, for the future newbies like me, after you post a thread, look at the end of the page for similar threads!
