<fontcolor="green">* **Action**:</font> Enter the address `com.unity.perception` and click _**Add**_.
**Note:** If you would like a specific version of the package, you can append the version to the end of the url. For example `com.unity.perception@0.1.0-preview.5`. For this tutorial, **we do not need to add a version**. You can also install the package from a local clone of the Perception repository. More inofrmation on installing local pacakges is available [here](https://docs.unity3d.com/Manual/upm-ui-local.html).
Each package can come with a set of samples. As seen in the righthand panel, the Perception package includes a sample named _**Tutorial Files**_, which will be required for completing this tutorial. The sample files consist of example foreground and background objects, randomizers, shaders, and other useful elements to work with during this tutorial. **Foreground** objects are those thatthe eventual machine learning model will try to detect, and **background** objects will be placed in the background as distractors for the model.
* **Action**: In the _**Package Manager**_ window, from the list of _**Samples**_ for the Perception package, click on the _**Import into Project**_ button for the sample named _**Tutorial Files**_.
<fontcolor="green">* **Action**:</font> In the _**Package Manager**_ window, from the list of _**Samples**_ for the Perception package, click on the _**Import into Project**_ button for the sample named _**Tutorial Files**_.
Once the sample files are imported, they will be placed inside the `Assets/Samples/Perception` folder in your Unity project. You can view your project's folder structure and access your files from the _**Project**_ tab of the editor, as seen in the image below:
* **Action**: The _**Project**_ tab contains a search bar; use it to find the file named `ForwardRenderer.asset`, as shown below:

### <aname="step-3">Step 3: Setup a Scene for Your Perception Simulation</a>
Simply put, in Unity, Scenes contain any object that exists in the world. This world can be a game, or in this case, a perception-oriented simulation. Every new project contains a Scene named `SampleScene`, which is automatically openned when the project is created. This Scenes comes with several objects and settings that we do not need, so let's create a new one.
* **Action**: In the _**Project**_ tab, right-click on the `Assets/Scenes` folder and click _**Create -> Scene**_. Name this new Scene `TutorialScene` and double-click on it to open it.
<fontcolor="green">* **Action**:</font> In the _**Project**_ tab, right-click on the `Assets/Scenes` folder and click _**Create -> Scene**_. Name this new Scene `TutorialScene` and double-click on it to open it.
The _**Hierarchy**_ tab of the editor displays all the Scenes currently loaded, and all the objects currently present in each loaded Scene, as shown below:
<palign="center">
As seen above, the new Scene already contains a camera (`Main Camera`) and a light (`Directional Light`). We will now modify the camera's field of view and position to prepare it for the tutorial.
* **Action**: Click on `Main Camera` and in the _**Inspector**_ tab, modify the camera's `Position`, `Rotation`, `Projection` and `Size` to match the screenshot below. (Note that `Size` only becomes available once you set `Projection` to `Orthographic`)
<fontcolor="green">* **Action**:</font> Click on `Main Camera` and in the _**Inspector**_ tab, modify the camera's `Position`, `Rotation`, `Projection` and `Size` to match the screenshot below. (Note that `Size` only becomes available once you set `Projection` to `Orthographic`)
<palign="center">
<imgsrc="Images/camera_prep.png"/>
For this tutorial, we prefer our light to not cast any shadows, therefore:
* **Action**: Click on `Directional Light` and in the _**Inspector**_ tab, set `Shadow Type` to `No Shadows`.
<fontcolor="green">* **Action**:</font> Click on `Directional Light` and in the _**Inspector**_ tab, set `Shadow Type` to `No Shadows`.
* **Action**: Select `Main Camera` again and in the _**Inspector**_ tab, click on the _**Add Component**_ button.
* **Action**: Start typing `Perception Camera` in the search bar that appears, until the `Perception Camera` script is found, with a **#** icon to the left:
<fontcolor="green">* **Action**:</font> Select `Main Camera` again and in the _**Inspector**_ tab, click on the _**Add Component**_ button.
<fontcolor="green">* **Action**:</font> Start typing `Perception Camera` in the search bar that appears, until the `Perception Camera` script is found, with a **#** icon to the left:
* **Action**: Click on this script to add it as a component. Your camera is now a `Perception` camera.
<fontcolor="green">* **Action**:</font> Click on this script to add it as a component. Your camera is now a `Perception` camera.
Adding components is the standard way in which objects can have various kinds of logic and data attached to them in Unity. This includes objects placed within the Scene (called GameObjects), such as the camera above, or objects outside of a Scene, in your project folders (called Prefabs).
To speed-up your perception workflow, the Perception package comes with four common labelers for object-detection tasks; however, if you are comfortable with code, you can also add your own custom labelers. The labelers that come with the Perception package cover **2D bounding boxes, object counts, object information (pixel counts and ids), and semantic segmentation images (each object rendered in a unique colour)**.
* **Action**: Click on the _**+**_ button to the bottom right corner of the empty labeler list, and select `BoundingBox2DLabeler`.
* **Action**: Repeat the above step to add `ObjectCountLabeler`, `RenderedObjectInfoLabeler`, `SemanticSegmentationLabeler`.
<fontcolor="green">* **Action**:</font> Click on the _**+**_ button to the bottom right corner of the empty labeler list, and select `BoundingBox2DLabeler`.
<fontcolor="green">* **Action**:</font> Repeat the above step to add `ObjectCountLabeler`, `RenderedObjectInfoLabeler`, `SemanticSegmentationLabeler`.
Once you add the labelers, the _**Inspector**_ view of the `Perception Camera` component will look like this:
You will notice each added labeler has a field named `Id Label Config`. By adding a label configuration here you can instruct the labeler to look for certain labels within the scene and ignore the rest. To do that, we should first create label configurations.
* **Action**: In the _**Project**_ tab, right-click the `Assets` folder, then click _**Create -> Perception -> Id Label Config**_.
<fontcolor="green">* **Action**:</font> In the _**Project**_ tab, right-click the `Assets` folder, then click _**Create -> Perception -> Id Label Config**_.
* **Action**: Rename the newly created `IdLabelConfig` asset to `TutorialIdLabelConfig`.
<fontcolor="green">* **Action**:</font> Rename the newly created `IdLabelConfig` asset to `TutorialIdLabelConfig`.
* **Action**: Select `TutorialIdLabelConfig` and in the _**Inspector**_ tab, click on the _**+**_ button to add 10 new label entries. Use the following exact names for these entries:
<fontcolor="green">* **Action**:</font> Select `TutorialIdLabelConfig` and in the _**Inspector**_ tab, click on the _**+**_ button to add 10 new label entries. Use the following exact names for these entries:
1 `candy_minipralines_lindt`
2 `cereal_cheerios_honeynut`
3 `cleaning_snuggle_henkel`
The label configuration we have created is compatible with three of the four labelers we plan to attach to our `Perception Camera`. However, `SemanticSegmentationLabeler` requires a different kind of label configuration which includes unique colors for each label instead of numerical IDs. This is because the output of this labeler are images in which each visibile foreground object is painted in a unique color.
* **Action**: In the _**Project**_ tab, right-click the `Assets` folder, then click _**Create -> Perception -> Semantic Segmentation Label Config**_. Name this asset `TutorialSemanticSegmentationLabelConfig`.
* **Action**: Add the same 10 labels from the above list to this new label configuration. Note how this time they each get a new unique color instead of a number:

* **Action**: Select the `Main Camera` object from the Scene _**Hierarchy**_, and in the _**Inspector**_ tab, assign the newly created `TutorialIdLabelConfig` to the first three labelers. To do so, you can either drag and drop the former into the corresponding fields for each labeler, or click on the small circular button in front of the `Id Label Config` field, which brings up an asset selection window filtered to only show compatible assets. Assign `TutorialSemanticSegmentationLabelConfig` to the fourth labeler. The `Perception Camera` component will now look like the image below:

In Unity, Prefabs are essentially reusable GameObjects that are stored to disk, along with all their child GameObjects, components, and property values. Let's see what our sample prefabs include.
* **Action**: In the _**Project**_ tab, navigate to `Assets/Samples/Perception/0.5.0-preview.1/Tutorial Files/ Foreground Objects/Phase 1/Prefbas`
* **Action**: Double click the file named `drink_whippingcream_lucerne.prefab` to open the Prefab asset.

<fontcolor="green">* **Action**:</font> Double click the file named `drink_whippingcream_lucerne.prefab` to open the Prefab asset.
When you open the Prefab asset, you will see the object shown in the Scene tab and its components shown on the right side of the editor, in the _**Inspector**_ tab:
In this tutorial, you will learn how to use the provided Randomizers, as well as how to create new ones that are custom-fitted to your randomization needs.
* **Action**: Create a new GameObject in your Scene by right-clicking in the _**Hierarchy**_ tab and clicking `Create Empty`.
* **Action**: Rename your new GameObject to `Simulation Scenario`.
* **Action**: In the _**Inspector**_ view of this new object, add a new `Fixed Length Scenario` component.
<fontcolor="green">* **Action**:</font> Create a new GameObject in your Scene by right-clicking in the _**Hierarchy**_ tab and clicking `Create Empty`.
<fontcolor="green">* **Action**:</font> Rename your new GameObject to `Simulation Scenario`.
<fontcolor="green">* **Action**:</font> In the _**Inspector**_ view of this new object, add a new `Fixed Length Scenario` component.
Each `Scenario` executes a number of `Iteration`s, and each Iteration carries on for a number of frames. These are timing elements you can leverage in order to customize your Scenarios and the timing of your randomizations. You will learn how to use Iteartions and frames in Phase 2 of this tutorial. For now, we will use the `Fixed Length Scenario`, which is a special kind of Scenario that runs for a fixed number of frames during each Iteration, and is sufficient for many common use-cases. Note that at any given time, you can have only one Scenario active in your Scene.
There are a number settings and properties you can modify here. `Quit On Complete` instructs the simulation to quit once this Scenario has completed executing. We can see here that the Scenario has been set to run for 100 Iterations, and that each Iteration will run for one frame. But this is currently an empty `Scneario`, so let's add some Randomizers.
* **Action**: Click _**Add Randomizer**_, and from the list choose `BackgroundObjectPlacementRandomizer`.
<fontcolor="green">* **Action**:</font> Click _**Add Randomizer**_, and from the list choose `BackgroundObjectPlacementRandomizer`.

<fontcolor="green">* **Action**:</font> Click _**Add Folder**_, and from the file explorer window that opnes, choose the folder `Assets/Samples/Perception/0.5.0-preview.1/Tutorial Files/Background Objects/Prefabs`.
* **Action**: Set the rest of the properties (except for `Seed`) according to the image below. The `Seed` attribute is the seed used for the underlying random sampler, and does not need to match the image shown.

As seen in the image above, what we have now is just a beige-colored wall of shapes. This is because so far we are only spawning them, and the beige color of our light is what gives them their current look. To make this background more useful, let's add a couple more `Randomizers`.
* **Action**: Repeat the previous steps to add `TextureRandomizer`, `HueOffsetRandomizer`, and `RotationRandomizer`.
<fontcolor="green">* **Action**:</font> Repeat the previous steps to add `TextureRandomizer`, `HueOffsetRandomizer`, and `RotationRandomizer`.

<fontcolor="green">* **Action**:</font> In the UI snippet for `RotationRandomizer`, change all the maximum values for the three ranges to `360` and leave the minimums at `0`.
Your list of Randomizers should now look like the screenshot below:
To make sure each Randomizer knows which objects it should work with, we will use an object tagging and querying workflow that the bundled Randomizers already use. Each Randomizer can query the Scene for objects that carry certain types of `RandomizerTag` components. For instance, the `TextureRandomizer` queries the Scene for objects that have a `TextureRandomizerTag` component (you can change this in code!). Therefore, in order to make sure our background Prefabs are affected by the `TextureRandomizer` we need to make sure they have `TextureRandomizerTag` attached to them.
* **Action**: In the _**Project**_ tab, navigate to `Assets/Samples/Perception/0.5.0-preview.1/Tutorial Files/Background Objects/Prefabs`.
* **Action**: Select all the files inside and from the _**Inspector**_ tab add a `TextureRandomizerTag` to them. This will add the component to all the selected files.
* **Action**: Repeat the above step to add `HueOffsetRandomizerTag` and `RotationRandomizerTag` to all selected Prefabs.

Once the above step is done, the _**Inspector**_ tab for a background Prefab should look like this:
It is now time to spawn and randomize our foregournd objects. We are getting close to generating our first set of synthetic data!
* **Action**: Add `ForegroundObjectPlacementRandomizer` to your list of Randomizers. Click _**Add Folder**_ and select `Assets/Samples/Perception/0.5.0-preview.1/Tutorial Files/Foreground Objects/Phase 1/Prefabs`.
* **Action**: Set these values for the above Randomizer: `Depth = 3, Separation Distance = 1.5, Placement Area = (5,5)`.

<fontcolor="green">* **Action**:</font> Navigate to the dataset path addressed in the _**Console**_.
In this folder, you will find a few types of data, depending on your `Perception Camera` settings. These can include:
- Logs
The output dataset includes a variety of information about different aspects of the active sensors in the Scene (currently only one), as well as the ground-truth generated by all active labelers. [This page](https://github.com/Unity-Technologies/com.unity.perception/blob/master/com.unity.perception/Documentation%7E/Schema/Synthetic_Dataset_Schema.md) provides a comprehensive explanation on the schema of this dataset. We strongly recommend having a look at the page once you have completed this tutorial.
* **Action**: To get a quick feel of how the data is stored, open the folder whose name starts with `Dataset`, then open the file named `captures_000.json`. This file contains the output from `BoundingBox2DLabeler`. The `captures` array contains the position and rotation of the sensor (camera), the position and rotation of the ego (sensor group, currently only one), and the annotations made by `BoundingBox2DLabeler` for all visible objects defined in its label configuration. For each visibile object, the annotations include:

* `label_name`: The object's label, e.g. `candy_minipralines_lindt`
* `instance_id`: Unique instance id of the object
To verify and analyze a variety of metrics for the generated data, such as number of foreground objects in each frame and degree of representation for each foreground object (label), we will now use Unity's Dataset Insights framework. This will involve running a Jupyter notebook which is conveniently packaged within a Docker file that you can download from Unity.

In order to to download the actual data from your run, we will now use Dataset Insights again. This time though, we will utilize some of the lines that were commented in our previous use with locally generated data.
You will generally require a large amount of data to train your computer vision model. Generating data in these practical sizes will take incredible amounts of time to finish if performed on typical workstation computers. This is where the cloud comes in. In this phase, you will learn how to:
* Generate large-scale synthetic datasets containing hundreds of thousands of frames by leveraging the power of **Unity Simulation** (USim).
* Keep track of your USim runs using the USim command-line interface (USimCLI).
* Keep track of your USim runs using the USim command-line interface (USim-CLI).
* Use Dataset Insights to download and analyze your cloud-generated data.
