I've been meaning to answer this post but have been quite busy. The
easiest way to use panoramas in PTViewer is to use the equirectangular
image. That way you can keep your high resolution cubics with tiling,
low resolution previews, and all the other bells and whistles you can
do with QTVR. You can do much the same with PTViewer but you will need
to hand code a lot of it.
There are three options for hotspots in PTViewer. You have a couple of
options for creating hot spots in PTViewer. Using one method, you
specify the coordinates of your hotspot in the html code. An easier
method if you have a lot of hotspots in an image or want to create odd
shapes, is to make a second equirectangular image containing your
hotspots that plays along with your panorama. Each of the hotspots on
is coded from zero to 255 based on the shade of grey of the hotspot.
Then in your html code, you only need to reference the grey value when
referencing the hot spot instead of trying to determine the coordinates
of the hot spot.

I was reviewing der Professor Dersch's notes on adding hotspots to
cubic VR to be compatible with PTViewer
while discussing the use of MakeCubicPPC to create cubic panos, he
writes that the hotspot images should be compressed as TIFF images or
else they won't be compatible with PTViewer
MakeCubicPPC does not offer any options for the compression of
hotspots - it always compresses as Graphics
now what? I could not find any other documentation on the web on
adding hotspots to VR which will be compatible with PTViewer
my goal is to author cubic VR compatible with both the QT plugin and
PTMViewer, including the hotspots
while I'm asking... he writes one should also make an equirectangular
hotspot image (in addition to the six hotspot cube faces). Why? And
what should I do with it once I've made it, if the six hotspot faces
were 'good enough'? This is not explained in the documentation.
see "Authoring suitable QTVR-panoramas" near the bottom of the page
thanks in advance
