Reverse engineering matteport coordinates

iif you send the glb and the json file, i can have a look at converting them into krpano coordinates

milotimbol

thanks!
first i though that uv-mapped low-res model is also visible in the transition (for better quality) ...
but i guess thats not true and it is only used for the dollhouse, what do you think?

about rotating see here
https://krpano.com/docu/xml/#depthmap.align

ps. such a tour could be done better by krpano,
but it needs more work / coding, so it would be more expensive.

From what I understand, the model is also used for the transitions between panos inside matterport. But not sure.

used yes, but there seems to be just the projection of point a fading to point b
the uv-mapping texture only used when you go into dollhouse mode

Yes, that is also how I preceive it: only the model is used for the 3D transitions between panos, no texture. Texture + model is used in the dollhouse.

@milo
yes 1 model only, used in 2 ways:
1) spherical projection with transition fading
2) uv-mapped for dollhouse

you sent me this link https://krpano.com/docu/xml/#depthmap.align doesnt seem to go to a section in the documentation. Can you point me to where the align for the depthmap is in the documentation?

you need to be in the 1.21 documentation
you can select that on the top left (click the version number)

or just use this link
https://krpano.com/docu/xml/?version=121

yes, the websites behaviour is confusing here...

Hello, Timblo going good job. hope you succussed in task.

Please help us with video

Thanks I can see it now, I didnt know I was looking at old documentation.

https://krpano.com/docu/xml/?version=121#depthmap

Code

<depthmap url="..." 
          texurl=""
          enabled="true"
          hittest="false"
          hittestmode="cpu"
          rendermode="auto"
          textured="auto"
          background="none"
          backgroundurl=""
          mapmode="1"
          offset="0.0"
          curve="1.0"
          scale="1.0"
          farscale="1.0"
          encoding="gray"
          axis="+x+y+z"
          cull="front"
          origin="0|0|0"
          align="0|0|0"
          subdiv=""
          />

Hi All,

I followed it and was able to successfully get an OBJ with texture. I used it as a dollhouse in krpano successfully.

The next thing I did was download the matterport 360 panoramas by listening to the network, downloading the tiles and then using krpano re-tile to convert them back to a sphere.

The part where I got stuck is trying to map the matterport numbers to krpano so I can put the 360 panorama and align it to the 3D model. See screenshot below

The closest I got is the screenshot below

It seems to fit but just need to rotate the image 90 degrees and cant seem to do it in krpano. So I did it in photoshop, which I believe shouldnt be the case since the purpose of this is to make everything automated.

Anyway my questions are
1. Is there a way to rotate the image without moving the depthmap? I
2. Has anyone successfully done this? like convert a matterport 360 tour to a krpano tour without using blender or everpano and just directly mapping matterport numbers to krpano.

May I ask how to convert w, x, y, and z in rotation quaternions into angles that depthmap.align can use[/url]

threejs has some functions for it:

I tried to convert quaternions to Euler angles, but the rotation angles of the model and panoramic image were incorrect when I included them in the krpano depthmap. My quaternion is:
Rotation:{
'x': -0.0012495082253
, "y": -0.005800439912
, "z": 0.5733134798673
, "w": 0.8193146205387
}

Converting to Euler angle is:
x: 0.300
y: -0.629
z: 69.958
But I need to set align="-0.0012495082253 | -110 | 0.005800439912" to work properly
My axis="- y+x+z", scale="100", origin="image"

Hi,

after some testing - when using the threejs quaternion to euler functions,
then the order "ZXY" and the following depthmap.align mapping seems to fit:

depthmap.align = (x) | (z-90) | (-y)

Best regards,
Klaus

After my testing, I found that it can work

depthmap.align = (x) | (z-180) | (-y)

I'm not sure why it's -180. Can someone explain
