Matterport

Vey nice, I particularly like the way you can simply walk around a property. Nice if we could do something similar in krpano.

Actually looking at the demo video it is not as intuative as I thought. Basically the walk around effect is made by mutiple positioned 360 images in each room, hallway etc they state a house can be done in 30-60 mins which I doubt but off course we can easily do this ourselves but it is time consuming. The one nice thing I like is the way it navigates through from one scene to another by highlighting hotspots but I am sure that probably can be done in krpano. Easypano also have this walkthough effect which was very good.

I saw that project about a year ago or something, the 3d model itself I find it is no good quality, for what I guess they take panos a part from making a 3d mesh.

The only thing I like from that tours, is the transition effect between panos, which hopefully we will be able to enjoy it with krpano at some point.

Also something that I lke is the ability of the cursor to know the geometry of the pano, which allows to know the rotation of the pointer, this is something we can also find in google street view.

Pretty cool platform. I also think the transitions between panos certainly provide a smoother walkthrough experience and the 3d model view is a part of this platform.But I guess there are some things to keep in mind with Matterport at this stage

- all imagery is processed and hosted by Matterport themselves. Sounds good, but then you have less control and what if the company goes broke? Will also be stuck with a useless but expensive camera. The imagery also cannot be archived by yourself.
You also have to pay a monthly hosting fee to Matterport.

- can't customise the interface. It only has standardised control interface with Matterport branding
- Matterport can only shoot interiors. Exteriors and night shots offer very shoddy quality.
- image quality is inferior - always desaturated colours and stitching errors you can't rectify. Also not 360x180. No multires. No zoom.
- long loading time currently and issues with viewing mobile devices

Many of these things will surely be rectified but for the outlay, I personally don't think it's worth it. I think better quality and experience can still achieved in the 'traditional' way.

It's only the smooth walkthrough transitions and fly out 3d model that set it apart and give the platform any appeal.

Yep, the only interesting thing is the "walking effect". See also my question and feature request a while ago regarding the walking effect:

Theoretically such would be possible of course - but a 3d-geometry (or a depth-map) for the pano would be required. The question is where to get or how to build that geometry? A normal pano image alone doesn't contain/provide that information.

Hi Klaus,

Maybe use three.js as an external js library :) ?

E.g. http://threejs.org/docs/#Referenc…shDepthMaterial

There is a misunderstanding - I don't mean how to render (that's the easy part) - I mean how to shoot/capture/record the 3d geometry or that depth map.

When you shoot a pano, you shoot only a flat 2d image without any deep information. There would a laser scanner or 3d-stereo-process required to build that 3d-data.

iStar seems to do that :

Maybe something like this Klaus :)?

hi

to my mind we would just need to orientate the whole panoramas of a virtual tour to get right direction for each, then creating walkthrough transitions should be ok, am i wrong?

why do we need 3D information involved?

best regards

Can we load a 3d map like matterport does?

Hi!
no, there is infrared scanner used for build real 3D model of space
So, it's impossible with standard panoramic equipment

Right, but I would like to use a 3d map of an exterior area. I shoot those with my drone. I'd like to be able to add hotspots to the map and load panos on click.
I'm looking for a way to integrate the wonderful krpano with some new 3d tech. I use drone deploy to get the 3d outside model. Like this: https://skfb.ly/GoEw
Any help is appreciated, thank you.

The ThreeJS plugin for krpano may be an option.
Use three.js (3d objects) inside krpano (with VR support)

I think that transition like zoomblend but with support of transition direction will be good enough
it is very hard to realize this blending type?

If the hotspots and the pano's are aligned properly, the effect is almost identical.

It's trivially easy. You can get the code from the examples on the KRpano site.

in my tours all scenes aligned properly and have virtual N-S-W-E. angle of view and fov is always keeped from one pano to another. visitors can do step right, left, back or any angle with chevron arrows or floating arrow (google street view style). but zoomblend always zoom forward.
it is at least stupid to zoom forward when step back was done
