unity-android-native-texture

Minimal example of how to dynamically update a texture in Unity on Android from native C++ code.
Should also work on Linux deployments with minimal changes, not tested yet.

Note: before deploying the Unity project, you need to build the native library in Assets/Plugins/Android/src/ by setting $ANDROID_NDK_ROOT and running build_plugin.sh. This uses the old-style ndk-build process, should be upgraded to CMake and properly integrated with Unity at some point.

Branches:

• master: a procedural texture in C passed to Unity
• camera: a live camera view from the NDK -> Unity
• opencv: live camera view processed with OpenCV -> Unity

Built/tested with:

• Unity 2018.2.4f1
• Android NDK r15c
• Android 8.0 Oreo (API level >= 24)
• OpenCV for Android 3.4.1
