Query on Mesh Merging & Refinement for Large Models in HOOPS Exchange & Communicator

[cad-developer]

Hello Tech Soft 3D Team,

We are working with very large CAD/3D models and are using HOOPS Exchange + HOOPS Communicator for conversion and visualization.

I would like to check:

1. In HOOPS Exchange, is there support for mesh merging — specifically, if we have a large model, can we convert it into a single mesh instead of many sub-meshes?

2. Does Exchange or Communicator provide options for mesh refinement/simplification (reducing polygon count while preserving geometry fidelity)?

3. If available, can these be controlled through Exchange conversion settings (e.g., SC/SCZ generation) or only by using post-processing APIs in Communicator?

4. Are there recommended workflows in Exchange to optimize large models before sending them to Communicator for viewing?

Looking forward to your guidance.

Thanks & Regards,

Hello,

Please find below answers to your questions:

1. There is no specific function for merging multiple meshes into a single mesh.
2. Converter does have the option --generate_LODs to control polygon count/level-of-detail.
3. An LOD example is provided in the Communicator package via the quickstart module:

• Launch the server by double-clicking start_server.bat found in the directory HOOPS_Communicator_2025.X.x\quick_start
• View the example in the Web Viewer by clicking this URL:
  http://localhost:11180/level_of_detail.html?viewer=csr

4. There really isn’t an optimization feature available prior to conversion.

Thanks,
Tino
