# Description

This PR adds the functionality to set up the view camera with respect to
different frames: world center, Environment Center, and an assets root
frame. In the last case, if the asset moves, the camera will track it.
This is a useful feature for recording videos during the training
logging.

# Description

Adds string checking to the functions which accept path-types, casting
them to a `str` if they are not already. Closing #421 in favor of this
fix, see discussion for initial rationale. This solution is superior
because this addresses all of the changes, not just the one causing a
test to fail.

Fixes #420

# Description

Previously, the contact sensor only measured the air time (last_air_time
and current_air_time). In this PR, the book keeps both the air-time and
contact time. Moreover, the arbitrary thresholding for detecting contact
is changed to a config parameter.

This is currently a non-breaking feature. But I suggest renaming
`ContactSensorCfg.track_air_time` to `ContactSensorCfg.track_intervals`.
This will make the PR a breaking feature.

# Description

When I updated `run_all_tests.sh` to be runnable from any dir (#406),
some debugging prints accidentally made it into the commit 😅
These make it quite hard to read the test output. This PR removes the
debugging `print()` calls and replaces a few others with `logging` calls
for consistency.

<!-- As a practice, it is recommended to open an issue to have

# Description

Previously, if you had two environments named `orbit` and `orbit_2024`.
If you delete the environment `orbit` to rename it, the grep search

exists.

This MR fixes the grep matching in `orbit.sh` to return success only if
the entire word matches.

* `collections.abc` is favored over `typing` for importing generic
types. The latter will be deprecated in future Python releases.

# Description

We frequently reinstall pip packages when building the docker, even when
the downloaded packages have not changed between builds. This allows us
to look in `/root/.cache/pip` (on the image) for cached pip packages.
This speeds up our build significantly.

Adds a [mount cache
](https://docs.docker.com/build/cache/#use-the-dedicated-run-cache)to
the Dockerfile for the line `${ORBIT_PATH}/orbit.sh --install --extra`,
significantly increasing speeds by preventing repeated downloads of
large packages

This MR pins the torch version to 2.0.1 in installing the `orbit` and

# Description

On termination of an episode, three conditions arise:

1. **bad** terminations (terminated dones): the agent gets a termination
penalty
2. **timeout** terminations (truncated dones):
* infinite-horizon: bootstrapping by the agent based on terminal state
    * finite-horizon: no penalty or bootstrapping

Currently, we have not handled the last case, which leads to issues when
training RL tasks with a finite horizon (for instance, Nikita's agile
locomotion work).

This MR adds a flag to the RLTaskEnvCfg called `is_finite_horizon` that
helps deal with this case. The flag is consumed by the env wrappers to
decide how they want to specifically handle the finite horizon problem.

From Isaac `2023.1.0-hotfix.1` to `2023.1.1`, `/app/livestream/enabled`
started to default to True. This breaks our logic w/r/t
`SimulationContext.render()`, which is now treating a headless instance
as one that needs full rendering. This causes problems with multiple
SimulationContext calls, and ultimately this bottoms out with this
[line](https://github.com/isaac-orbit/orbit/blob/670a8c97db645d50a3ea89b06f7366fc2212fc06/source/extensions/omni.isaac.orbit/omni/isaac/orbit/sim/simulation_context.py#L563)
sending us into an infinite rendering cycle from which i.e. unittest
cannot exit.

I fix this problem by setting `/app/livestream/enabled` to explicitly
False in AppLauncher unless otherwise requested. This corrects the hang.

Ultimately, the answer to this is #238, but in the meantime we need a
fix or this is a showstopper for unit testing.

Fixes #323

# Description

This MR changed the shape of
`omni.isaac.orbit.sensors.contact_sensor.ContactSensorData.force_matrix_w`
in
[ContactSensor#L215-L217](https://github.com/NVIDIA-Omniverse/orbit/blob/963f3045367be3ccdac4f0902ac2103fcbb6070f/source/extensions/omni.isaac.orbit/omni/isaac/orbit/sensors/contact_sensor/contact_sensor.py#L215-L217)
from `(num_envs, num_bodies, num_shapes, num_filters, 3)` to `(num_envs,
num_bodies, num_filters, 3)`. This makes the returned tensor shape valid
with the data obtained from PhysX.

Fixes #193

# Description

This MR fixes running of single environments (`num_envs=1`). Previously,
in the `InteractiveScene` class, physics cloning happened when the
`replicate_physics` flag was set to True even if there was only one
environment.

# Description

We currently have X11 forwarding enabled by default. This is convenient
for certain users who want graphical displays (including IsaacSim
itself) to be forwarded from within the container. However, it is also
partially dependent upon the configuration of the host system and
requires a valid .Xauthority file which may or may not have been
created. Because this has introduced difficulties for several of our
users, I submit that we comment this portion out be default, until a
solution which allows either a `./container.sh` option, a variable in
`.env`, or both can be used to conveniently enable this option on an
affirmative basis.

If we can agree on this change, I will update the documentation
correspondingly.

# Description

The FrameTransformer sensor always assumed that the source frame index
is 0 in the parsed regex expression. However, a recent issue appeared
where this is not the case, and it led to a bug due to the hard-coded
value. This MR fixes the source frame index in the sensor and also adds
a unit test to check this behavior.
