  Rika	1. No, no textures whatsoever are loaded by HTTP other than map textures. Period. I studied it with a packet sniffer.

  Rika	2. Yes, textures do load faster otherwise anyway. That they load slower for others at the same time implies that they did something to UDP

•

  Rika	fetch too, and not just textures.

•

  Rika	3. As usual with official viewers, an NVidia GX260 and Core 2 Quad 'do not meet minimum requirements'.

•

  Rika	4. Some textures - the ones that load faster - fail to load completely at all.

  Rika	5. First it cleared my cache. Then it put it's own into a different location /anyway/, bloody thing.

  Rika	In short, not fit to be a main viewer yet, though a diff of what exactly happened to UDP fetch would be interesting.

•

  Rika	But my guess is, it's a different packet size or something simple...

  interesting analysis.

  Rika	Upon some further reflection and waiting for inventory to reload with an open texture console...

•

  Rika	1. It also seems to load LESS textures. I.e. the number of simultaneous fetches is smaller.

  Rika	2. Right now I'm staring at the same texture being reloaded from the sim every second...

  I got 3 blue screens of death in a row, using it.

  Rika	If it actually limits textures to load only to those that can be seen, most texture prefetching will become useless.

•

  Rika	The viewer side of the HTTP texture download code is completed though, no doubt about it. If it worked, it would get rid of 80% of all lag.

• 
  Jul 01, 2009 - 03:08AM

  Rika	It's just that the server side doesn't exist.

• 
  Jul 01, 2009 - 03:09AM

  Rika	Map can be loaded off http because it's stored on Amazon S3 for slurl.com anyway. Everything else would need a server on the sim side.

  wonders

  if and when they will get the server side finished to help reduce lag?

•

  Rika	There has been no word whatsoever on the topic that I heard.

• 
  Jul 01, 2009 - 03:11AM

  Rika	The code is pretty clear - viewer asks the caps system which URL to get textures from ("GetTexture" cap request)...

• 
  Jul 01, 2009 - 03:12AM

  Rika	...and then http-requests them off there giving texture key as a GET parameter to a web-something (which can be anything).

• 
  Jul 01, 2009 - 03:12AM

  Rika	That anything doesn't exist yet, so "GetTexture" request results in nothing.

• 
  Jul 01, 2009 - 03:13AM

  Rika	Mind you, they had the viewer side, unfinished and commented out in the published source, all the way since when it was first published.

• 
  Jul 01, 2009 - 03:13AM

  Rika	Well, it's now finished. It hasn't even been three years.

•

  Rika	How time flies </sarcasm>

  Thanks! Didn't understand a lot of that but what I did explains much of what I've seen and sounds really cool.

  Rika, I noticed an advanced menu option to turn on HTTP textures.. I'm sure you would have toggled this on in your tests?

  I've been using it. Been getting a strange error where prims rezzed onto a surface (eg table) sink slightly into the surface

  Not sure if that's snowglobe or my prims...

  sorry, error is the wrong word. Strange *behaviour*

• 
  Jul 01, 2009 - 04:49AM

  Rika	Yes, obviously I turned the option on. I had it on forever, actually, because internally it's still the same ImagePipelineUseHTTP

• 
  Jul 01, 2009 - 04:50AM

  Rika	Prims rezzed onto a surface sinking into that surface happens to me in 1.22 sometimes too.

• 
  Jul 01, 2009 - 04:50AM

  Rika	I think it's related to floating point and altitude.

  Thanks, Rika! Soft Linden tends to confirm what you say, too, although nobody at the lab seems to be aware of what Philip's group doing.

  They all believe that nothing works on the server side yet. Hmm. I wonder, though, if we could get OpenSim to work with it

  Rika	Get it to answer caps request with a sensible root URL and put a php script nearby that extracts blobs from sql asset storage, it will.
