Second Life for Oculus

As builders plan for a world to be seen by Oculus Rift users we hear a bit more about building things to real life scale. It is a good idea and has many benefits.

What we aren’t hearing much about is how to avoid making visitors sick, simulator motion sickness. I suppose many think that the Oculus Rift people will take care of such problems. The Oculus people are certainly putting thought and engineering into building a system that will avoid giving people simulator sickness. But, they advise those building for Oculus headsets to make sure they can keep their frame rates above 60 FPS…

I suspect the majority of Second Life users seldom see 60 fps. I know with my Quad Core and GTX560 I seem to get 25 to 50 FPS most of the time. If I am in a crowd, it is more like 8 to 12.

It may have features that will not be in the official Release 10 and lack features that may show up in the final release. But, for those that want to see the next Windows, you’ll be able to chase down some form of it tomorrow. See: Microsoft Announces Windows 10.

Second Life Bits 2014-40

The Euclideon People are Back

About three years ago we started to hear of a company that said they could do amazing things with 3D imaging and rendering, unlimited detail with high frame rates. Well, we have yet to see anything but videos. And now we have another video.

May be we will see something other than a video in 2015.

I also wonder if High Fidelity’s use of voxels is along the same line and if some of this tech might make it into SL2.

CtrlAltStudio Releases DK2 Second Life Support

David Rowe, lead developer for CtrlAltStudio’s Oculus Viewer and Firestorm contributor, has released preliminary support for the Oculus Rift DK2, developer’s kit 2. This is the improved Oculus with better head tracking and higher resolution screen.

Read more here: Preliminary Rift DK2 Support: 1.2.2.41183 Alpha.

In motion tracking the big change in the Oculus which requires changes to programs supporting it, is from adding tracking of head leaning/position. Head rotation is what was previously tracked. To understand the difference think of locking your shoulders against your seat back and moving your head by only flexing your neck. That is head rotation. If you bend at the waist and lean forward, you don’t use many neck muscles but you head moves a lot. It is this latter motion that has been added to the Oculus’ abilities.

Think of leaning out a car window to look at the ground. You will use a combination of head turning and body motion to see around the car door. It is supposed to be this sort of motion the Oculus has gotten better at.

Telling Second Life Viewers how to move the camera to simulate this type of motion is being added.

David does not have all of the new stuff working in the viewer. It is, as he writes, “…very preliminary”. But, it is a start for those with DK2’s.

512k Internet Slow Down

There is currently a problem with the Internet. Some time ago I wrote of the change from IPv4 to IPv6, which is a change in the standard way of assigning Internet addresses to devices. We were running out of addresses. New hardware capable of handling larger addresses has to be added and has been being added for the last couple of years.

Now another growth pain is starting to impact users as the Internet grows more complicated. We are seeing slow Internet and sites we cannot connect to because the routers that direct traffic from place to place run out of memory. The older routers can typically hold 512,000 addresses. Sounds like plenty. But, that is what they thought about addresses too.

The problems are hitting in the USA and Canada as older routers max’d out. The problem right now is that Border Gateway Protocol (BGP)routing tables have grown too large for some top-level Internet routers to handle. The result is that these routers can no longer properly handle Internet traffic. The result is they get confused and fail to rout anything, forget some routes and stop forwarding traffic destined for those routes, or just ignores that traffic. Whatever they do, your connection slows to a crawl as the system tries to find a way to route you packet to the destination or fails altogether.

You can figure out if you are running into this problem by doing trace route testing. See my Troubleshooting your Connection. If you are hitting the problem you will see your packets fail to get past some router.

The problem has to be fixed by the Internet Service Providers, mostly the backbone providers. About all you can do is suffer and complain to your ISP. The Trace Route information will help them get THEIR complaints to the right people.
