Positioning a 3D object
Hi Folks! I've had my Wave 2 device for a grand total of 3 hours now, but I have been playing with unity and the emulator for weeks. So this is the very first time I have been able to try one of my prototypes on the device itself. I think I'm missing something fundamental now that I'm in the actual 3D environment.
I'm building something almost exactly like this:
https://www.youtube.com/watch?v=uqS5Dx9O66c
That is, I have a CAD model of a large physical object. I want to place it in the room so I can walk around it. In real life the object is a 20' by 2' cylinder with a number of components. I have fully rendered this with no problem in Unity and it will display in the emulator fine. I have removed the skybox, selected black as my background color, and enabled "virtual reality supported" in my build settings. I can deploy it to the device with no problems (Kudos MS for making the device pairing easy!).
Remember I've only had this for hours. But the first thing I did was place a tiger and earth hologram into mid air, resize, and walk around them. That was VERY cool. I thought I should be able to do this with my unity app too. It launches and runs but I don't really place in the room. and if I walk towards it, it just seems to recede from me. I can't get "behind" it.
This is so central to the HL experience. What is the obvious thing that I have missed?
(I'm still blown away by this whole experience btw!)

For the mesh not displaying, It's pretty likely that you haven't enabled the spatial perception capability. You can get there in Unity by:
- control+shift+b to bring up build settings
- Click player settings. The inspector (usually on the right) will switch to player settings
- Switch the tab to the windows store tab
- Scroll down to and expand 'publishing settings'
- Spatial perception is all the way at the bottom. You likely will need to move two scroll bars to get to it.

Thank you everyone. it was a combination of problems. The main issue was probably the scale and placement of my models and the camera FOV in unity was definitely wrong. I'm having no problems at all adding 3d items to my scenes!

It sounds like you're placing it a fixed distance relative to the main camera.
Can we see what your unity project's hierarchy panel looks like? Maybe it'll give us a hint to how you set up the world.
And if you do want to place the item in the world, our github HoloToolkit has a basic "tap to place" script. There's also a test scene in there to show how to get it to run. It's a starting point and you can add more functionality to get it how you'd like.
Hey Simus,
Did you go through Holograms 100? This should let you know all of the switches and knobs you need to tweak in Unity to make the app Holographic.

My scene in Unity
I created an empty game object and added the three required managers. I attached the tap to place script to my "CLS" object (the parent of my hierarchy)
Patrick I did go through 100 but I guess I should do it again to see what I missed. I have not tried the tap to place sample scene, I will do that right now.
Does the wire frame mesh for spatial mapping appear in the correct place?

No mesh is displayed when the app launches. I must not have one of the managers configured properly

Is it hard to build such an app or is it really as easy as converting your cad model into .obj ander import it in unity? How did it work out for you and are you happy with the result?
