3D Layer Conversion Table

  • Updated

The table below summarizes the 3D layer conversions supported in TerraExplorer:

Legend:

  • UI - Direct conversion via user interface
  • Command Line (CL) - Direct conversion (via SLMeshConverter command line tool). More about: Command line tool >
  • Indirect – Indirect conversion – first convert to 3DML/o3DML and from 3DML/o3DML to the required format
  • * - Only for PhotoMesh-generated 3D layers
  Output Formats
3DML o3DML 3D Tiles Esri I3S /SLPK Bentley 3MX Models (DAE, OBJ, GLB, FBX) LAS/ LAZ

Importing and Exporting Using the Command Line

In addition to the format conversions supported from TerraExplorer user interface, additional conversions can be performed from the SLMeshConverter command line tool:

  • 3D Tiles to: 3D Tiles, I3S/SLPK, 3MX, and o3DML
  • OSGB to: 3D Tiles, I3S/SLPK, 3MX, and o3DML
  • o3DML to o3DML
  • 3DML to o3DML
  • 3DML to LAS/LAZ

To convert, construct a single command line that includes all the following:

  1. Run SLMeshConverter

    "c:\program files\Skyline\TerraExplorer Pro\SLMeshConverter.exe" -cmd convert
  2. Define the input layer:
    -in "FullPathToFile"

    • For 3DML/o3DML – Full path to the file

    • For 3D Tiles – Full path to the tileset.json

    • For OSGB – Full path to the root OSGB file or filelist.txt file. More about: Importing and converting OSGB layers > 

  3. Define the output format:

    • For 3DML

      -f 3dml

    • For 3D Tiles

      -f b3dm

    • For o3DML

      -f b3dm -m 2

    • For I3S

      -f i3s

    • For SLPK

      -f i3s -m 2

    • For 3MX

      -f 3mxb

    • For LAS/LAZ

      -f las

      Note:    The LAS/LAZ distinction is determined by the -out file name extension.

  4. Set the output WKT by defining the path to a file containing the WKT in a single line. If this parameter is not provided, the output will be in the same coordinate system as the input layer. WKT is a text file with the well known text in it.

    -wktout "C:\WKTFiles\4326.wkt"
  5. Specify the path to the output folder or file.

    • Folder output – For formats that generate a folder structure (e.g., 3MX, 3D Tiles), specify the full path to the output folder. E.g.,

      -out "C:\ConvertedLayers"
    • File output – For formats that generate a single file, specify the full path to the output file, including the appropriate file extension (e.g., .3dml, .slpk, .osgb, .las, .laz). E.g., 
-out "C:\ConvertedLayers\outputfile"

Note: For OSGB, specify the full path to the root OSGB file. E.g., 

-out "C:\ConvertedLayers\Tile_000106_000090.osgb"

 

Examples:

Convert 3DML to 3D Tiles

"C:\Program Files\Skyline\TerraExplorer Pro\SLMeshConverter.exe" -cmd convert -in "D:\Pune_Block_10_Build_2_ATGCP01.3dml" -out "C:\Data\Tilest.json" -f b3dm

 

Convert 3D Tiles to o3DML

"C:\Program Files\Skyline\TerraExplorer Pro\SLMeshConverter.exe" -cmd convert -in "C:\Data\Tilest.json" -in "D:\Pune_Block_10_Build_2_ATGCP01.o3dml" -f b3dm -m 2

 

Convert o3DML to i3s

"C:\Program Files\Skyline\TerraExplorer Pro\SLMeshConverter.exe" -cmd convert -in "C:\Data\model.o3dml" -out "D:\model" -f i3s
