About

A Vulkan-powered Android app targeting Chrome OS devices that showcases their potential to run high-peformance graphics applications. Should also run on Android phones.

Best experienced with a MIDI controller for a tactile experience, can also be enjoyed using a touchscreen/keyboard and mouse.

Explore combinations of glsl filters interacting with the camera preview stream and then capture a shareable animation sequence.

Requirements

• Device with Android 8.1 or higher
• Vulkan 1.1 or higher
• Device with a camera or USB webcam

Optional:

• MIDI controller with 6 sliders/knobs and one button

Building

Currently this uses a staticly built and linked version of shaderc and a fixed NDK version. There are better ways of doing this and I hope to update the project to include one soon. In the meantime, to "just get it to build" please follow the following steps:

• Import the project into Android Studio (2020.3.1 Arctic Fox or later)
  • Update and gradle or library dependencies (automatic links should work)
• Install NDK 22.1.7171670:
  • Go to Tools->SDK manager->SDK Tools tab
  • Click checkbox "show package details" to list all versions
  • Expand "NDK Side-by-Side"
  • Check version 22.1.7171670
  • Click apply to download install
• Update local.properties to have: ndk.dir=/home/YOURHOMEDIR/Android/Sdk/ndk/22.1.7171670
• Build shaderc (replace SDK/NDK directories as needed):
  • Go to the command line
  • cd ~/Android/Sdk/ndk/22.1.7171670/sources/third_party/shaderc
  • ../../../ndk-build NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=Android.mk APP_STL:=c++_static APP_ABI=all libshaderc_combined
• Note: In build.gradle, abiFilters is set to build ARM32, ARM65, x86_32, and x86_64 ABIs to maximize device support. You may adjust this if required.
• Build project
