ft-lab/omniverse_sample_scripts/Extensions/readme.md | # Extension
簡単なサンプルのExtensionです。
Extensionはモジュール的にOmniverse(Kit)を使ったアプリを拡張します。
ExtensionはベースはPythonとして記載し、別途C言語(動的ライブラリとして関数呼び出し)で外部機能を実装することができます。
## Extensionの詳しいドキュメント
Extensionは構成のルールがあります。
Omniverse Createの[Help]-[Developers Manual]からOmniverse Kitのドキュメントの「Extensions」で詳しく解説されています。
## Extension作成に関する情報
* [extension.tomlでの記述内容](./knowledge/config_info.md)
## サンプル
|Extension|説明|

|[ft_lab.sample.hello](./ft_lab.sample.hello)|開始(startup)/破棄(shutdown)のみの簡単なExtension|

```
### __init__.py
開始するメインファイル (hello.py)のインポートを指定します.
```
from .hello import *
```
### hello.py
Extensionの開始時と終了時に呼び出すメソッドを指定します。
```python
import omni.ext
class HelloExtension(omni.ext.IExt):
# Call startup.
def on_startup(self, ext_id):
print("[ft_lab.sample.hello] HelloExtension startup")
# Call shutdown.
def on_shutdown(self):
print("[ft_lab.sample.hello] HelloExtension shutdown")
```
このときのクラス名"HelloExtension"はどのような名前でも認識されるようでした。
"on_startup"でExtensionを開始したときの処理を記載します。
"on_shutdown"でExtensionを終了したときの処理を記載します。
## Omniverse CreateにExtensionを入れる
Omniverse Createが"pkg/create-2021.3.8"にインストールされているとします。
このとき、開発者が作成したExtensionを"pkg/create-2021.3.8/exts"に入れます。
なお、"pkg/create-2021.3.8/kit/exts"はOmniverse KitとしてのExtension、
"pkg/create-2021.3.8/kit/extscore"はコアExtensionとなり、
これらはOmniverseの内部的に使用されるExtensionのため、ここには独自Extensionは入れないほうがよさそうです。
作成した"ft_lab.sample.hello"をフォルダごと"pkg/create-2021.3.8/exts"に格納します。
Omniverse Createを起動したままでもExtensionを所定のフォルダに入れると、自動的にExtensionが認識されます。
メインメニューの"Window"-"Extensions" を選択し、Extensionsウィンドウを表示します。
Extensionのリストで"Python Extension Example"が存在するのを確認できました。

```python
omni.kit.menu.utils.add_menu_items(self._menu_list, self._menu_name)

```python
def term_menu (self):

# Remove and rebuild the added menu items.
omni.kit.menu.utils.remove_menu_items(self._menu_list, self._menu_name)
asyncio.ensure_future(_rebuild_menus())
```
「omni.kit.menu.utils.remove_menu_items」で追加したメニュー項目を削除。
「asyncio.ensure_future(_rebuild_menus())」で遅延でメニューを更新しています。
## Omniverse CreateにExtensionを入れる
Omniverse Createが"pkg/create-2021.3.8"にインストールされているとします。
作成した"ft_lab.sample.menu"をフォルダごと"pkg/create-2021.3.8/exts"に格納します。
Omniverse Createを起動したままでもExtensionを所定のフォルダに入れると、自動的にExtensionが認識されます。
メインメニューの"Window"-"Extensions" を選択し、Extensionsウィンドウを表示します。
Extensionのリストで"Python Extension Example"が存在するのを確認できました。
これをOnにすると、"MenuTest"というメニュー項目が表示されます。
Offにした場合"MenuTest"内は空になりますが、トップメニューの"MenuTest"は残ってしまうようです (Omniverse Create 2021.3.8で確認)。
Omniverse Code 2022.1.0ではこの問題は起きなかったため、この現象は将来Kit側で修正されるものと思われます。

ft-lab/omniverse_sample_scripts/Extensions/knowledge/config_info.md | # extension.tomlでの記述内容
"extension.toml"に記載する内容の覚書です。
## 他のExtensionを使用し、機能を呼び出したい
他のExtensionの機能を使用したい場合、[dependencies]にExtension名を追加します。
```
[dependencies]
"omni.audioplayer" = {}
```
この場合は「omni.audioplayer」を有効にします。
こうすることで、Pythonで「import omni.audioplayer」が使用できるようになります。
なお、参照で記載するExtension名は [[python.module]] に記載しているものと同じになります。
以下は「omni.audioplayer」内の"extension.toml"の記載です。
```
[[python.module]]
name = "omni.audioplayer"
```
ここで記載しているExtensionがOnになっていない場合は、対象のExtensionを起動した時に自動的にOnになります。
## 外部のC/C++モジュールを呼び出す
Windows環境の場合、dllの形で外部関数を作成します。
これをExtensionから呼び出すことができます。
```
[[native.library]]
path = "bin/win/x64/OmniverseSimpleDLL.dll"
```
DLL呼び出しのサンプルExtensionは「[ft_lab.sample.callDLL](../ft_lab.sample.callDLL)」をご参照くださいませ。

カメラ操作を行います。
カメラはUsdGeom.Camera ( https://graphics.pixar.com/usd/release/api/class_usd_geom_camera.html ) を使用します。
Omniverse Kit.102では「omni.kit.viewport」を使っていましたが、kit.103では「omni.kit.viewport_legacy」となりました（とりあえずの変更）。
kit.104では「omni.kit.viewport_legacy」は廃止になっています。
```python
import omni.kit.viewport.utility
# Get active viewport window.
active_vp_window = omni.kit.viewport.utility.get_active_viewport_window()
viewport_api = active_vp_window.viewport_api
# Get camera path ("/OmniverseKit_Persp" etc).
cameraPath = viewport_api.camera_path.pathString
```
としてviewport_apiからカメラのPrimパスを取得します。
kit.104は"Viewport 2.0"となっており、複数のViewportを持つことができます。
そのため、アクティブなビューポートを"omni.kit.viewport.utility.get_active_viewport_window()"から取得してきています。
## サンプル

|[UnitsToCentimeters](./UnitsToCentimeters)|Stageの単位をセンチメートルに統一（MetersPerUnitを0.01にする）|

ft-lab/omniverse_sample_scripts/Samples/CreateSimpleCurve/readme.md | # CreateSimpleCurve
Xform内の複数のSphereを使用し、Spbereをスプライン補間したチューブ形状を作成します。
## 使い方
複数のSphereを配置します。
このSphereをつなぐようにスプラインでチューブ形状がMeshとして作成されることになります。
また、Xformに対してマテリアルを割り当てておきます。
Xformを選択した状態でScript Editorで「[CreateSimpleCurve.py](./CreateSimpleCurve.py)」を実行します。
Create Curveウィンドウが表示されました。
"Number of divisions"で分割数を指定して"Create"ボタンを押します。
Sphereを曲線上でつないだチューブ形状がMeshとして生成されます。

ft-lab/omniverse_sample_scripts/Samples/UnitsToCentimeters/readme.md | # UnitsToCentimeters
Stageの単位をセンチメートルに統一します。
[UnitsToCentimeters.py](./UnitsToCentimeters.py) は、
metersPerUnitを0.01に変換するスクリプトです。
## 使い方
このスクリプトは、StageのmetersPerUnitが0.01（センチメートル）でない場合に
DefaultPrimのscaleを調整し、metersPerUnitを0.01に置き換えます。
ルートPrimがXformで「DefaultPrim」の指定がされているのが必要条件になります。
なお、Nucleus上のusdファイルの場合はmetersPerUnitの変更が許可されないことがありました。
そのため、このスクリプトはローカルのusdに対して行うようにしてください。
なお、このスクリプトはファイル保存は行いません。
必要であれば、処理後にusdファイルを保存してご使用くださいませ。
