Folks,
Once in awhile we receive requests for the source code for the online model converter. It is built on a few internal frameworks at AGI so we have not released the source; however, I wrote a small code sample in node for a REST service that converts COLLADA to glTF using collada2gltf:
https://github.com/AnalyticalGraphicsInc/collada2gltf-web-service
This should be a good starting point for a full-featured conversion web service. Just a warning that this is the first web service I’ve ever written in node…
