Matterport VR + Unity 5 + Oculus Rift -> ???357

Subject : Unity 5 + Oculus rift + Matterport.

1. Can the matterport scan ultra-high resolution meshes with ultra high resolution textures?

2. If so? Are these .obj read and write protected?

3. Can I just open the files without any restrictions?

4. Has anyone tried decimating the meshes?

5. Has anyone tried turning the textures into atlases?

6. Would that work?

Does anyone here understand my questions? If not, feel free to ask more questions.

The meshes I've seen are really low resolution, as well as the colors that map to those meshes. The high resolution panos aren't available (yet), but even if they were, I'm not sure how you'd connect the mesh to that higher resolution imagery. Decimating the meshes could give you higher resolution geometry, but you wouldn't have colors at higher res to match. I'm certainly not a Matterport or 3D modeling expert, so please take these guesses with a grain of salt!

Thank you for the reply. I read the article, however nothing on the resolution of the meshes.

Oh I get it. The color data of the geometry is stored per vertex. Decimating the geometry would result in very muddy color data and the lost of the texture definition.
Makes perfectly sense.

I know in Zbrush, you can temporarily store vertex color data to a temporarily UV layer called GUV.
Not quite sure if this GUV data can be reprojected on a decimated mesh.
If G.U.V's won't cut it. I am sure there is another way.

My guess (take this with a grain of salt)
If the high-resolution data (colors and mesh) is high, so crisp and sharp. It could be worth while to do a re-topo of the high resolution and bake out (render to texture) the high res color data to a optimized low resolution mesh so it can be used accordingly in a game engine.
Since the meshes are drawn and processed twice, it might worth the effort to do this for Gear VR.

@kc1302 there might be a way to map the hi-res panoramas to the low res mesh. Just to be clear, I believe there is no high res mesh. From what I understand, the Matterport device has a completely different device that's measuring depth to create the meshes. Microsoft's kinect was similar in that the depth resolution was only 500px or so, even though the camera image was much greater.

It might be possible to make something that looks good, but I haven't seen anything yet. It would be really cool!

You can view a few examples of what the mesh MP looks like and what kind of resolution you get here:

I do not think MP will ever make the 18 images or pano data avalible from what I can tell.

The obj files are not protected but the obj is made up of layers (approx 1 per scan) but the layers are not organized to correspond with info taken at a specific location. A layer may contain information spread over the entire property. Decimating the mesh puts all these layers together but does not influence the appearance in my opinion.

The mesh is great for large scale items and things like couches, beds, etc.

bad for reflective surfaces and items with thin or fine detail, fixtures, railing, etc.
