Android - Getting RendererException After Adding Shadow Filters

Hello Guys,
I’m getting this exception after adding DirectionalLightShadowFilter+SSAOFilter filters:

So the question is - is it a known issue and what is the best way in Android to render shadows?

Thanks!

I think I have tried the ambient occlusion before but it didn’t work as I remember, but I will try it again, generally using DirectionalLightShadowRenderer would be efficient for android devices, bloom filter is also good but too much filters will slow down a test case, what if it were a game then ?! Filters need optimizations on android…

In frag & vert shaders, usually most jme files are handled against GLSL of GLES, in this case I think if there’s no visual error as its here, then those files are not handled against GLSL of GLES…that would involve writing some code in ShaderSource[name=Common/MatDefs/Shadow/PostShadowFilter15.frag & it should hopefully work…

EDIT : IN CPP/c native, preprocessor arguments are #MACRO 110 or macros, they occur before the program being compiled, so #extension directive should be the glsl version declared at the top of the file, so if we have identified the version for glsl, then that may work

NB : if the version is not specified then its by default glsl110, which may break things…

I tried the DirectionalLightShadowRenderer:

final int SHADOWMAP_SIZE=1024;
        DirectionalLightShadowRenderer dlsr = new DirectionalLightShadowRenderer(assetManager, SHADOWMAP_SIZE, 3);
        dlsr.setLight(sun);
        viewPort.addProcessor(dlsr);

It crashes the emulator but works fine on the physical device.
Good enough for now.

Could you please send the crash in another thread ? So we can now if its a bug or something.

well… I checked again with the physical device and the DirectionalLightShadowFilter filter is also working fine BUT the performance are horrible :slight_smile:

        FilterPostProcessor fpp = new FilterPostProcessor(assetManager);

        DirectionalLightShadowFilter shadowFilter = new DirectionalLightShadowFilter(assetManager, 4096, 4);
        shadowFilter.setLight(sun);
        shadowFilter.setShadowIntensity(0.3f);
        shadowFilter.setShadowZExtend(256);
        shadowFilter.setShadowZFadeLength(128);
        // shadowFilter.setEdgeFilteringMode(EdgeFilteringMode.PCFPOISSON);
        fpp.addFilter(shadowFilter);

        SSAOFilter ssaoFilter = new SSAOFilter();
        fpp.addFilter(ssaoFilter);

        viewPort.addProcessor(fpp);

Im not sure I understand - this thread is about the exception in the emulator. What other thread to open?

8

I think if so, may be the physical processes the bad compilation of the shader file…but if there’s a bad compilation or a warning, then its better be fixed

I mean If the crash is different, you better create another thread

It’s the one and only crash I have. It happens only in the emulator. So - both filters works fine on the physical device but crashes the emulator. I will try to check some more devices to get a better picture of the problem

BTW @sgold MaVehicles lib seems to work fine on Android. I just need to figure out best practice for the input controls but that’s for another thread :slight_smile:

You can use my library for so, instead of doing textures, it uses android views, but you will need to use JmeSurfaceView on jme3.4.0-beta, I have sent you the demo back before but it lacks some docs in some places…

EDIT : if you have faced in a bug inside it, report at once, I will fix that bug or add docs of what was missed…
