Question

OBJ to SLPK conversion of large 3D models

Hi all,

I'm manually fixing broken photogrammetric models of buildings (common errors like holes in overlit white walls etc.) and then I want to convert these fixed OBJ models to SLPK. I use this workflow:

  1. OBJ Reader – merge mesh parts: yes, move to coordinate system: yes, coordinate system: EPSG:5514 (Czech/JTSK.Krovak),
  2. Offsetter (to move it to correct geolocation) – X Offset: -747078.00223783311, Y Offset: -1054893.7301940639, Z Offset: 289.74612628016621,
  3. Esri Indexed 3D Scene Layer Writer – coordinate system: EPSG:5514 (Czech/JTSK.Krovak), geometry: i3s_terrain_mesh.

...but no file is created. I guess the problem is probably that the models are really big (over 0.5 GB)?

 

Thanks for your help,

Michal

Hello @kolarius27​, thanks for sharing the workspace and logfile. Sorry to hear you've had issues writing thus far, would you be able to share a sample dataset? If you're unable to share data publically, consider creating a case with us! Happy to help, Kailin.

Hello @kailinatsafe​ , thanks for answering. I'm not the owner of these files, so I've created a case (C687349). And I have another question...is SLPK writer able to create HLOD for 3D models to be streamable online (something that Cesium ion does for example)?

Thanks for your help, Michal.
