Getting bounding box of alembic file with command line tools ?

[Nicholas Yue]

Hi,

  Are there some flags I can pass to abcinfo/abcecho to display the bounding box of an Alembic file ?

Cheers

abcinfo -af foo.abc/.childBnds/0

Will print out the first sample in optional archive bounds, along with
the frame number it corresponds with. (assuming 24 fps)

Does it require a certain version of abcinfo ?

I am using the abcinfo from the Houdini 18.0.460 distribution and I got the following

```
nyue@head0:~$ abcinfo -af monkey.abc
monkey.abc, version: 10712 (2 timings)
   TimeSample[0]      1 samples:  t0=0 (frame 0.0 @ 24fps)
   TimeSample[1]      1 samples:  t0=0.0416667 (frame 1.0 @ 24fps)

DOH! I meant abcls.

I dont recognize abcinfo, so it might be a Houdini provided utility.

Thanks for the heads up. There is no abcls shipping with Houdini, I will build the latest Alembic from the repo.

Cheers
