Well you do realize that the Constellation is a totally different tracking solution I suppose. There are like dozens of cameras on the Vive and the controllers. And the lighthouse paints the entire room with lasers. So the cameras(sensors) on the Vive will always see some sort of laser pattern hitting the walls, ceiling, etc. There is almost no occlusion unless you try to cover deliberately sensors on the headset and the controllers (like tuck the controller under your arm or something).
Occlusion is pretty huge here.

The CV1 HMD will do 360 with high precision with one camera.
Full stop. No question.
So for 360 room scale with no occlusion do I need 1, 2 or 4 cameras?

Doesn't lighthouse work by the light emitted from the lighthouse hitting the sensor on the headset? I believe so, and that leaves it susceptible to occlusion.

Yeah but the Oculus has one or two cameras. It can see only whats in front of you. If you turn around and it cannot see the lights on the touch controllers because your body is blocking it then it will lose tracking.
"davidjc" wrote:No, the Vive only has two laser emitters not "emitters all over the walls". The sensors on the Vive and controllers have to have direct line of sight to one of the two emitters. The occlusion is exactly the same as the Rift.
And vive put laser emitters all over the walls by using the Lighthouse boxes to illuminate everything in 15ft x 15ft (or greater) area. ... The vive controllers and headset sees all around it and only has to see a wall, floor, or ceiling with the laser pattern on it.

Sorry but you don't understand how the lighthouse works. It doesn't read patterns on the walls, and reflections are explicitly disallowed in the setup instructions (ie you are required to cover all reflective surfaces).
It is line of sight from lighthouse to IR receiver with a laser sweep. When the sweep hits a receiver on the headset or controller it registers a position. See this video:

It reads the light patterns in the room, the lasers fill the room. There is no occlusion issues. But keep deceiving yourself if you want to.
Another video, I mean honestly try to be honest with yourself. These guys are pushing the Vive tracking beyond its limits.

Honestly I'm done here. It's silly. Lighthouse > Constellation. I can see how its open to discussion.

Except that the whole room is lit up with the lasers. Can you occlude an entire room? Not really possible. So its not susceptible to occlusion unless you get a towel and wrap it around the controller or something. The tracking volume of the vive is 15 by 15 feet. And covers to at least so that you can hold the controllers over your head and probably still some.

Try this... put the lighthouse behind an object such that the Vive has no line of sight but can only see reflections on the walls. Then you will understand that it doesn't work.
When you understand that the lighthouse is still based on line of sight you will realize that "volume" is not a relevant basis of comparison.
