Getting bootstrapped

[rhaleblian]

Hi Carson, thanks for sharing this.
FYI, I'm looking at adapting the Hydra plugin to work with our cut of USD, which is pretty recent.
If things go well, we will attempt to internally package it separately from USD itself.

Close at will,

hi ray,
great to hear! Let me know if you run into issues.

the code as it is now is far behind current USD as I've been on other projects/leave since siggraph- I just yesterday started getting back to updating the OSPRay USD code with the latest USD release actually. Once that's finished I'm planning on updating the repo to only include the plugin code and tag releases with specific USD/hydra releases. We are planning on packaging this in some form later on - possibly even binary releases.

status update:
I have updated the code to latest USD dev and extracted out only the plugin code in branch "plugin". It appears to partially work now if put into the USD source plugin directory, though there are a few issues such as the framebuffer not clearing properly. I have also put the code in a self contained cmake project which can be built externally to USD, however I haven't gotten it working with USD if built externally yet.

I have finished the hdOSPRay standalone build and checked that into master. The code was updated to work with the latest USD dev version. I have discovered that some forms of the instancer are not working correctly with some new usd models I have just gotten access too and am working through those issues now.

Hi Carson! I'm just getting back to this. Let me pull down what you have and sync it with the build setup I have. I'll get back to you early next week.

I had success building and pathing the plugin into our build-and-deploy structure, which doesn't copy plugins into the USD tree but includes them from a master plugInfo.json. As seen above, usdview can see the Hydra backend.

BTW i am working atop USD v18.11.
