"Depth Data Accuracy Issues in Rendering 3DGS Scenes within Isaac Sim"

Here is the professional English translation of your technical inquiry:

"Since RTX supports the Interactive Path Tracing rendering mode and can improve the depth data accuracy of 3DGS scenes, how exactly can we call an API to capture depth data from a 3DGS scene using this interactive path tracing approach?

It seems that the documentation for isaacsim.replicator.synthetic_recorder, isaacsim.sensors.camera, and OmniGraph nodes doesn’t mention this at all."

“3DGUT also supports secondary lighting effects, including reflections, refractions through unification with 3DGRT. This is critical for synthetic object insertion and multibounce illumination. These lighting cues significantly affect how AI agents interpret depth, surface boundaries, and object material properties—making their inclusion vital for testing and improving behavior in complex, uncertain conditions.”

If you are looking for the python code to change from realtime to pathtracing here is the code:

import omni.kit.actions.core

action_registry = omni.kit.actions.core.get_action_registry()
action = action_registry.get_action(
    "omni.kit.viewport.actions",
    "set_renderer_rtx_pathtracing",
)
action.execute()

In reverse:

import omni.kit.actions.core

action_registry = omni.kit.actions.core.get_action_registry()
action = action_registry.get_action(
    "omni.kit.viewport.actions",
    "set_renderer_rtx_realtime",
)
action.execute()

)
