Description
|
||||
===========
|
||||
|
||||
This folder contains resources for using Draco within Unity development.
|
||||
Currently we support two types of usages:
|
||||
* Import Draco compressed mesh as assets during design time.
|
||||
* Load/decode Draco files in runtime.
|
||||
|
||||
Prerequisite
|
||||
============
|
||||
|
||||
To start, you need to have the Draco unity plugin. You can either use the
|
||||
prebuilt libraries provided in this folder or build from source.
|
||||
Note that the plugin library for different platforms has different file extension.
|
||||
|
||||
| Platform | Library name |
|
||||
| -------- | ------------ |
|
||||
| Mac OS | dracodec_unity.bundle |
|
||||
| Android | libdracodec_unity.so |
|
||||
| Windows | dracodec_unity.dll |
|
||||
|
||||
Prebuilt Library
|
||||
----------------
|
||||
|
||||
We have built library for several platforms:
|
||||
|
||||
| Platform | Tested Environment |
|
||||
| -------- | ------------------ |
|
||||
| .bundle | macOS Sierra + Xcode 8.3.3 |
|
||||
| armeabi-v7a(.so) | Android 8.1.0 |
|
||||
| .dll | Win10 + Visual Studio 2017 |
|
||||
|
||||
Build From Source
|
||||
-----------------
|
||||
You can build the plugins on your own for OSX/Win/Android. Source code for the wrapper is here: [src/draco/unity/](../src/draco/unity). Following is detailed building instruction.
|
||||
|
||||
Mac OS X
|
||||
--------
|
||||
On Mac OS X, run the following command to generate Xcode projects. It is the same as building Draco but with the addition of `-DBUILD_UNITY_PLUGIN=ON` flag:
|
||||
|
||||
~~~~~ bash
|
||||
$ cmake path/to/draco -G Xcode -DBUILD_UNITY_PLUGIN=ON
|
||||
~~~~~
|
||||
|
||||
Then open the project use Xcode and build.
|
||||
You should be able to find the library under:
|
||||
|
||||
~~~~ bash
|
||||
path/to/build/Debug(or Release)/dracodec_unity.bundle
|
||||
~~~~
|
||||
|
||||
Windows
|
||||
-------
|
||||
Similar to OS X build, you need to build Draco with the additional `-DBUILD_UNITY_PLUGIN=ON` flag, for example:
|
||||
|
||||
~~~~~ bash
|
||||
C:\Users\nobody> cmake path/to/draco -G "Visual Studio 14 2015" -DBUILD_UNITY_PLUGIN=ON
|
||||
~~~~~
|
||||
|
||||
Or to generate 64-bit version:
|
||||
|
||||
~~~~~ bash
|
||||
C:\Users\nobody> cmake path/to/draco -G "Visual Studio 14 2015 Win64" -DBUILD_UNITY_PLUGIN=ON
|
||||
~~~~~
|
||||
|
||||
Android
|
||||
-------
|
||||
|
||||
You should first follow the [Android Studio Project Integration](../README.md#android-studio-project-integration) to build Draco within an Android project. Then, to build the plugin for Unity, just add the following flag to build.gradle.
|
||||
|
||||
~~~~ bash
|
||||
cppFlags "-DBUILD_UNITY_PLUGIN"
|
||||
~~~~
|
||||
|
||||
You should be able to find the plugin library under:
|
||||
|
||||
~~~~ bash
|
||||
path/to/your/project/build/intermediates/cmake/debug(or release)/obj/your_platform/libdracodec_unity.so
|
||||
~~~~
|
||||
|
||||
Change file extension
|
||||
---------------------
|
||||
Because Unity can not recognize un-native file extension, you need to change your compressed .drc file to .drc.bytes so that Unity will recognize it as binary file. For example, if you have file `bunny.drc` then change the file name to `bunny.drc.bytes`.
|
||||
|
||||
Copy Library to Your Project
|
||||
----------------------------
|
||||
Copy the plugin library to your Unity project in `Assets/Plugins/`.
|
||||
For Android:
|
||||
|
||||
~~~~ bash
|
||||
cp path/to/your/libdracodec_unity.so path/to/your/Unity/Project/Assets/Plugins/Android/
|
||||
~~~~
|
||||
|
||||
For Mac:
|
||||
|
||||
~~~~ bash
|
||||
cp path/to/your/dracodec_unity.bundle path/to/your/Unity/Project/Assets/Plugins/
|
||||
~~~~
|
||||
|
||||
For Win:
|
||||
|
||||
~~~~ bash
|
||||
cp path/to/your/dracodec_unity.dll path/to/your/Unity/Project/Assets/Plugins/
|
||||
~~~~
|
||||
|
||||
|
||||
Copy Unity Script to Your Project
|
||||
---------------------------------
|
||||
Copy the scripts in this folder to your project.
|
||||
Copy wrapper:
|
||||
|
||||
~~~~ bash
|
||||
cp DracoMeshLoader.cs path/to/your/Unity/Project/Assets/
|
||||
~~~~
|
||||
|
||||
Copy extened AssetPostProcessor which enables loading (This file is only used for import Draco files):
|
||||
|
||||
~~~~ bash
|
||||
cp DracoFileImporter.cs path/to/your/Unity/Project/Assets/Editor/
|
||||
~~~~
|
||||
|
||||
---
|
||||
|
||||
Load Draco Assets in Runtime
|
||||
============================
|
||||
For example, please see [DracoDecodingObject.cs](DracoDecodingObject.cs) for usage. To start, you can create an empty GameObject and attach this script to it.
|
||||
|
||||
Enable Library in Script Debugging
|
||||
----------------------------------
|
||||
If you have library for the platform you are working on, e.g. `dracodec_unity.bundle` for Mac or `dracodec_unity.dll` for Windows. You should be able to use the plugin in debugging mode.
|
||||
|
||||
---
|
||||
|
||||
Import Compressed Draco Assets
|
||||
==============================
|
||||
In this section we will describe how to import Draco files (.drc) to Unity as
|
||||
other 3D formats in design time, e.g. obj, fbx.
|
||||
To note that importing Draco files doesn't mean the Unity project will export Draco files as models. It will not save space when exported to package.
|
||||
|
||||
If you have followed the previous steps, you just need to copy your asset, e.g. `bunny.drc.bytes`, to `Your/Unity/Project/Assets/Resources`, the project will automatically load the file and add the models to the project.
