Hi Ben,
Heres my take on what I would do,
Option 1 - Some kind of screen capture solution to stream a location of the master screen to a video asset in the slave screen. It would be across the local network (WIF though) so not sure about quality?? The slave screen will be 4K 98"
You could create a UDP stream using OBS and then bring it inside Intuiface with the video asset we have done this across a local network streaming it from one PC to another. Use this help article link Setup UDP stream to the second PC
Option2 - For the 3d model use the native 3D IF model asset in both master and slave and send the x /y / rotation coordinates to the same model on the slave screen via network triggers. I tested something similar to this and it wasn’t a very fluid experience in that it waits for you to stop manipulating before sending the value so its not a seamless “in sync” experience. This also will not help me with wanting to do the same with a web browser
If you are using the first option you wouldn’t need to have this functionality have your two machines on a shared excel/airtable base when the model is moved update the rows and on the slave, machine gets values from excel/airtable? Maybe worth a try?.
Option 3 - Do the 3d model in something like unity or unreal and use Paolo’s examples of wizardy to integrate into intuiface. Although I’m not sure about those platforms ability to do what I’m after. As above this does not help me with the requirement to mirror the browser as well.
What sort of 3D models are you wanting to display? is it really detailed models or just simple models? regarding the unity intergration side of things check out Mihais post from 2016 Unity Starter Package and Documentation
But for Options 4 and 5 give my suggestion about Option 1 a go and let me know how you get on?
Kind Regards
Louie
