Open usdview without specifying a file #3093

Open jakeanq opened 6 months ago

jakeanq commented 6 months ago

Description of Issue

It would be useful to be able to launch usdview without being required to specify a file path, in which case it would open to an empty stage.

Use-cases for this:

Users who would prefer to use the File→Open menu option to find their USD files.
Writing a .desktop file (or equivalent for other OSs) so that usdview can be launched from system menus.
Writing a usdview plugin which determines what to open (perhaps selecting from an asset browser or dynamically generating USD content).

Steps to Reproduce

Run usdview with no arguments; it will print error: the following arguments are required: usdFile

System Information (OS, Hardware)

Tested on Arch Linux, hardware not applicable.

Package Versions

usd 24.03

Those are great points, @jakeanq ! Given our other priorities and roadmap, this is something we might not get to for awhile, but we'd be very interested to look at a PR for this, if anyone is willing!

I would like to work on this issue for ASWF Dev Days, Sep. 26-27, 2024. I have experience working with OpenUSD python and C++ API and have used usdview. Please let me know if there are any concerns.

Hi! We'd love your contribution! We're not hooked into the full Dev Days apparatus, but here are contributing guidelines for OpenUSD! The first thing we'd need is a signed CLA in order to accept your PR. You can find links and instructions at the very top of the contributing guidelines page :)

Hello hello! I am also interested in working on this issue for Dev Days. I was informed that a CLA was just signed on behalf of Netflix Animation for some of us to be able to contribute to OpenUSD.

Would you be willing to collaborate on this @MishDivyAmzn? :)

MishDivyAmzn commented 1 month ago

Hey,

I have requested a signed CLA from my employer. I'll send it as soon as it is ready.

I have this feature working on my machine. I am just writing some tests, and then I will test on other platforms (Windows, Linux and MacOS). If you are still interested in collaborating then I am down. But I also understand if you would prefer to tackle some other issue. :)

Sounds like you've already got this one covered! I'll have a browse at the other issues. Happy dev!
