Дополненная реальность (Augmented Reality) не является какой-то новой технологией, но ее применение было замечено широкой публикой с появлением игры Pokemon GO, которая показала, что технология AR имеет большой потенциал. В книге рассмотрены различные способы разработки приложений с дополненной реальностью, от нативной разработки в Android Studio до использования таких движков, как Unity.
Wikitude
Wikitude SDK дополненной реальности сочетает в себе технологии 3D-трекинга (на основе Simultaneous Localisation and Mapping (SLAM)), распознавания образов, слежения и геолокации AR для мобильных устройств, планшетов и смарт-очков. Доступны также расширения для Unity, Cordova, Titanium и Xamarin.
После регистрации на сайте Wikitude (https://www.wikitude.com/) можно открыть веб приложение Wikitude Studio (http://studio.wikitude.com/dashboard).
Панель Wikitude Studio позволяет создать проект, который будет служить контейнером для целевых изображений, используемых в качестве эталона для распознавания образов, при их появлении в камере устройства.
После добавления целевого изображения в проект, выберете тип дополненной реальности:
Text – отображает текст поверх целевого изображения.
Image – отображает изображение поверх целевого изображения.
Button – отображает кнопку поверх целевого изображения, при нажатии на которую можно перейти по URL адресу.
HTML Widget – HTML код, отображаемый поверх целевого изображения.
3D Model – отображает 3D модель поверх целевого изображения. Предварительно 3D модель конвертируется из FBX (.fbx) формата в Wikitude 3D Format (.wt3) с помощью Wikitude 3D Encoder.
Video – отображает видео поверх целевого изображения.
После выбора типа дополненной реальности и определения свойств объекта дополненной реальности, отображаемого поверх целевого изображения, нажмем кнопку Preview.
Установим на Android устройство приложение Wikitude App из Google Play.
Откроем приложение и в меню выберем Developer. Введем логин и пароль в Wikitude Studio. Выберем проект и наведем камеру устройства на целевое изображение – увидим дополненную реальность.
Нажмем кнопку Export в Wikitude Studio веб браузера. Здесь можно экспортировать приложение для доступа из Wikitude App и Wikitude Hosting, загрузить приложение для хранения на собственном сервере, а также загрузить проект приложения для разработки в среде IDE на основе Wikitude SDK.
При использовании Wikitude Hosting или собственного хостинга, URL адрес приложения вводится в приложении Wikitude App, в разделе Developer, в Wikitude Studio, для загрузки приложения.
Для разработки приложения в среде Android Studio, скачаем проект приложения на основе шаблона Android App Template и импортируем его в Android Studio.
После исправления ошибок в настройках проекта, приложение можно запустить на Android устройстве.
Скачаем Wikitude SDK (https://www.wikitude.com/download/) и получим лицензионный ключ, который вставим в protected static final String WIKITUDE_SDK_KEY = ""; файла WikitudeSDKConstants чтобы убрать водяные знаки из вида камеры. В результате все равно останется водяной знак Trial.
В папке libs проекта находится архивный файл Wikitude SDK. В папке assets проекта находится то самое приложение, которое скачивается при выборе Self-Hosting в Wikitude Studio веб браузера.
При запуске приложения сначала запускается активность RuntimePermissionRequestActivity, в которой запрашивается разрешение android.permission.CAMERA, после этого запускается активность SampleCamActivity, расширяющая класс AbstractArchitectCamActivity.
В классе SampleCamActivity в переопределенном методе getARchitectWorldPath возвращается путь к файлу index.html приложения папки assets. Если вы хотите загрузить приложение с сервера, в строке WORLD_PATH укажите URL адрес файла index.html.
В классе SampleCamActivity в переопределенном методе getWikitudeSDKLicenseKey возвращается лицензионный ключ, указанный в строке WikitudeSDKConstants.WIKITUDE_SDK_KEY.
В классе AbstractArchitectCamActivity создается экземпляр класса StartupConfiguration Wikitude SDK, в конструкторе которого указывается лицензионный ключ. Также создается основной вид приложения, представленный классом ArchitectView Wikitude SDK.
В классе StartupConfiguration лицензионный ключ передается в строковое поле класса.

}
private boolean a() {

}
public StartupConfiguration(String string, int n2) {

}
public StartupConfiguration(String string, int n2, CameraPosition cameraPosition) {
this.a = string;

DEFAULT,
FRONT,
BACK;
private CameraPosition() {
}
}
public static interface Features {
public static final int Geo = 1;
public static final int Tracking2D = 2;
}
}
В классе ArchitectView в методе onCreate лицензионный ключ передается из класса StartupConfiguration в строковое поле класса ArchitectView и в методе onPostCreate вызывается нативный метод setKey(this.getContext().getPackageName(), startupConfiguration.getKey()). Далее имя пакета и лицензионный ключ сравниваются в нативной библиотеке папки jni Wikitude SDK.
