Create Integrated Mesh Scene Layer Package Tool

gauthierverlin

Hello,

I'm trying to use this tool but I can't make it works. I was wondering if this tool works with OpenScenGraph 3d model made with Photoscan.

I have checked all the possible solution to resolve error 999999 but it still won't work.

If you have any idea how this tool works with 3d OSGB model made with Photoscan, I'll be glad to hear about it.

Best regards

Gauthier

Hi Dirk,

I don't see any sample OSGB output data so ill see if I can generate some from a trial version of the software. I'll report back once I have some more information.

thanks,

Andrew

... well, I can not share the data without further complex legaly agreements.

I was hoping nframes could provide you some data samples https://www.nframes.com/gallery/

Andrew Johnson

Hi Dirk,

Are you able to share the dataset with us? Unfortunately without inspecting the dataset we will not be able to know for 100% certainty if this is a naming issue or some other issue.

thanks,

Andrew

Hello Andrew,

I just had the same problem, trying to create mesh-slpk in arcgis-pro v2.3 from osbg files generated with SURE-Software by nframes.

Datastrukture looks like this

Each tile-folder contains data-levels and a node, the root folder contains also an "master" osgb-file.

I played a little arround with renaming filenames to your conventions, but without success.

It would be great if you could also trimm the Arcgispro-Converter to understand this output, maybe you can also get in contact with that company for Details?

best regards,

Dirk

Yes that does help! Please note none of our scene layer tools support creating scene layers with a custom coordinate system. We require a well known id (WKID) but we do have it in our backlog to support custom coordinate systems. We are planning on getting this work done either in 2.4 or 2.5. Regardless, this isn't the cause of the problem as I can reproduce this problem on my end using an anchor point with a projected coordinate system. Our developer has a utility that can interrogate the binary file to determine whether or not its written out properly by Photoscan. We recently discovered an issue where ContextCapture was not writing out the child nodes properly in the root nodes leading to failures in our tool so in these situations it is difficult to know the exact cause until the osgb file can be interrogated. Our developer is traveling this week so there may be a delay in getting back to you but i'll reach out as soon as I have more information.

thanks,

Andrew

Our Local coordinate are different for every structure we work for. We usually take some points on the structure and some points around it with the origin of the coordinate system (0,0,0) not far. We usually took something like X = 2000 m, Y = 4000 m and Z = 100m.

It's more like no coordinate system if we want to find a equivalent. For example, when we import our orthophotos in Arcgis Pro, we don't reference coordinate system and this kind of "no coordinate system" are detected as "Unknow" which is fine for us.

On this capture, you can see that our coordinate are around X = 100 m, Y = 300 m and the coordinate system of the .tiff is "Unknown".

But we can't do this with 3d model (.slpk) as they are automaticly referenced in GCS WGS84 and VCS EGM2008 Geoid.

Althought, we would like to be able to reference our map and coordinate systems with this "Unknow" system but it isn't possible.

Hope my answer helps you.

Thank you again

Thanks for this information and for sharing the data. One more follow up question, when you say local coordinate system do you mean custom coordinate system or just a local projected coordinate system?

thanks,

Andrew

If I export the model from Photoscan in .slpk and I import it in a scene, the model look like this :

Of course it's an example to test if this method works before using it on larger model as we work with model of bridge or dam for example.

My goal, by using the Create Integrated Mesh Scene Layer Package Tool is to give an Anchor point to my 3d model.

When exporting a 3d model from Photscan in .slpk format, the coordinate system of the model will always be transformed in WGS84 + VCS EGM2008 Geoid. As we are trying to work in Local system or just different system than WGS84, exporting model into .osgb format from Photoscan provide us the possibility to export it in local coordinate system.

That's why this tool look promising as I could use a .osgb 3d model in a local coordinate system and transform it into a .slpk using the tool from Arcgis Pro and giving it an Anchor Point to place it where I want on the map.

Here is the link to my OSGB data : https://drive.google.com/open?id=17wljvtmkL3_GzLSmuxH-y6mjMvcOfAv8

Thank you for all the answers and the interest you give to my problem

Best regards

Thanks for providing that information. Typically OSGB data should be output into a hierarchy where each tile root node will have its own folder so you would have Tile001, Tile002, Tile003, etc. Our importer expects the data to be structured in a certain way so that the tree hierarchy can be properly constructed. Without being able to take a look at this data its difficult to investigate this further. We have seen issues where the children nodes are not declared in the parent nodes or the data is all lumped into one folder structure and the imported is not able to differentiate the tile nodes when building the tree hierarchy. Are you able to provide the OSGB data so we can take a look on this end to determine the specific cause of the failure?

thanks,

Andrew

Hello,

I kept it the way Photoscan exported it. Here is the file I try to import :

It's all group into one folder I named "OpenScenGraph" as you can see in the input section of my first question.

Andrew Johnson

Hi,

How are the OSGB files structured in the folder that you input? Was that how Photoscan output the files or did you move everything into one folder?

thanks,

Andrew
