Just found yet another AR library for Android called ARmsk. The description sounds promising. But the demo video is kind of shocking. They have like half a frame per second. The code looks like they used a lot of examples, like the OpenGL Cube renderer from the Android API demos and some stuff from the OpenCV-Android examples.
Last updates were in January this year, so quite up-to-date actually.
Oh, btw, guys why can't I find you when I search for "AR Android". I mean seriously, take care of your website keywords 😉
AndEngine is a 2D OpenGL Engine. Actually a game engine. But it has also some small AR extension. I've stumbled upon this project a little while ago but then somehow forgot about it and now rediscovered it. So far it looks promising (even though I already found some kind of "lazy bug" which prevents the AR example to run 😕 ). Especially the the animation stuff and sensor helpers look great.
Hopefully this can boost my project a little.Will see.
Just another desperate try to get something connected with OpenCV compiled under Windows.
AndroidExperimental looked promising at the beginning. But of course everything just works on Linux without problems.
The step where
get_ndk_toolchain_linux.sh is referenced won't work on Windows and actually you don't need to do everything in there if you already have the NDK. So, assuming the NDK is already installed, just run the last portion of the script. The following is what worked for me with Cygwin.
ANDROID_NDK was defined in the Windows environment variables and therefore had backslashes in it, somehow this wouldn't want to work, so I overwrite it.
NDK_TMPDIR is used in the shell script and with Cygwin it has no write access to this folder. Choosing another folder worked.
export ANDROID_NDK=/cygdrive/d/android-ndk-windows export NDK_TMPDIR=$ANDROID_NDK/../ndk-tmp $ANDROID_NDK/build/tools/make-standalone-toolchain.sh --platform=android-5 --install-dir=$ANDROID_NDK/android-toolchain --system=windows ln -fs $ANDROID_NDK/android-toolchain /opt/android-toolchain
So, this prep-work is done. Unfortunately compiling the
hello-cmake sample didn't work and ends with:
-- Check for working C compiler: /cygdrive/d/android-ndk-windows/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc -- broken CMake Error at /usr/share/cmake-2.8.4/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE): The C compiler "/cygdrive/d/android-ndk-windows/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc" is not able to compile a simple test program.
I'm not sure why this is happening. Maybe it's because the path to the project has spaces in it. Or what ever.
Trying something else for now.
