Creating custom annotator

[christianbarcelo]

Hi!

I wanted to know if there’s any tutorial on how to create custom annotators for Replicator. I’m pretty sure it can be done by reading the source code, but some extra guidance to be sure I’m not messing with anything internal would be great.

perhaps this post by the mod may shed some light:

Custom annotator

Hi there, creating custom annotators is not documented at the moment. You can however do this, either by accessing available data from omnigraph nodes, or data from already existing annotators. You can get started by taking a look at the annotators examples from replicator: /omni/replicator/core/scripts/annotators_default.py Or the dope/ycb writers from the pose estimation tutorial, which are also using custom nodes and annotators for the writer: /omni.replicator.isaac/python/scripts/writ…

or perhaps @ahaidu can offer some additional insight if you were to elaborate on your goal since it’s not well documented at this point yet.
