SVF2 Support #51

Closed florolf1 closed 2 years ago

florolf1 commented 3 years ago

Hey,

I just found out that all derivative functions only work for models in svf format. Downlod derivatives as svf/glft/otg/f2d for models in svf2 format does not word.

Is it planned to add support for svf2?

Hi there!

That's correct. When you convert your designs into the svf2 format, the Model Derivative service will only create svf2 outputs, meaning that there will be no svf(1) or f2d available for downloading. As for the glTF download, the glTF files are actually converted from svf(1), so it's the same situation.

The SVF2 format is a bit more difficult to download (it's not just a bunch of files you can download) but I'll see if we can support it, too.

Thank you for the feedback. For my pipeline, i need to convert the svf files to gltf in order to continue working with them on mobile devices (AR/VR). However, some Revit models are so large (1GB +) that I have switched completely to svf2 format which has improved the viewer performance immensely. But as already mentioned, I need the possibility to convert the models into gltf.

If you can be helped with the conversion support, I would be willing to work with you.

Alternatively, I think it is also possible to convert model into SVF and SVF2 at the same time? Is that correct?

Thanks Florian! If you're willing to look at the code and submit a PR I'd be happy to look at it.

I can't find it anywhere in the official Forge docs now but I believe that you can only specify one output format (SVF or SVF2), not both :( One workaround (a bit annoying in my opinion) would be to translate your model into SVF(1), download it as a glTF, and then start another translation, this time into SVF2...

In order to make the glTF download work for all cases, we would basically have to support direct SVF2-to-glTF conversion. Note that the forge-convert-utils library (used by the vscode extension) does already include an experimental support for OTG-to-glTF (OTG is the old codename for SVF2) but that code would still need some work.

After discussing the OTG/SVF2 topic internally, a decision was made not to support manual downloading and parsing of these formats. There were various technical, legal, and business reasons for this. I will remove the OTG option from the VSCode extension.
