   RE: [xml-dev] Wrapping Scripted Media in RSS: Secure?

[ Lists Home | Date Index | Thread Index ]

I don't get the question, Sterling.  That post was 
about the inherent insecurities of script languages 
inside content.  RSS is not an exception.

As to your comment, good graphics and 
video cards are a must for modern 3D, certainly, and 
scenegraph technologies without a doubt.   Better 
transport is a nice to have, but so far, multicasting 
appears to be working with current technologies.  Even 
broadband is not required.  

For example, on Wednesday and Saturday nights, the Jewel 
of Indra 3D site hosts parties.  The Blaxxun VRML servers 
are hosting multiuser worlds with avatars running up to a 
hundred behaviors per avatar, and from a separate site 
in San Francisco (Ratty Radio) streaming real time audio 
music of very good quality into the local player.  

I can log in, chat, have local 
audio for voices (synth) and do all of this over 
a 56k dialup (max is 48k really) and crash only if I 
fail to clear the cache.  Is it perfect?  No but it 
is adequate, works now, and is waaay better than what 
was tried when we did the Midsummer's Night Dream 
project some years ago.

In other words, we may be pushing the limits but the 
limits are not what we thought they would be five years 
ago.  We may not know precisely what the limits are 
except for too many lights in a scene.  And that we've 
always known about. Better graphics cards help. ;-)

Seems to me a good set of graphics cards with new and better video cards 
could do wonders for 3d.  Do we really need a better packet transport 
technology than packets ?
