Android Port

[Nadro]

COGLESTexture doesn't need COGLES2ExtensionHandler, because these filer are prepared for 2 different drivers ES1 and ES2. For copy library you have to define ANDROID_HOME. Define it, and rebuild Irrlicht. Switched colors will be fixed soon. Example 08 and others require additional stuff, so make sure that you prepared properly code (similar to example 17).

BTW. Which phone are you use and which Android version?

[ent1ty]

Well, what about the low framerate on ogl es 2.0? Like I said, it's a Nexus 7 - i can play gta vice city there on >40 fps at all times, irrlicht quake 3 map demo on 14 is just plain unacceptable


Edit: also, how can you possibly compile everything correctly without including the COGLES2ExtensionHandler in COGLESTexture, if this is what COGLESTexture.cpp looks like:

//COGLESTexture.cpp
[...]
#ifndef GL_BGRA
    // whoa, pretty badly implemented extension...
    if (Driver->FeatureAvailable[COGLES2ExtensionHandler::IRR_IMG_texture_format_BGRA8888] ||
        Driver->FeatureAvailable[COGLES2ExtensionHandler::IRR_EXT_texture_format_BGRA8888] ||
        Driver->FeatureAvailable[COGLES2ExtensionHandler::IRR_APPLE_texture_format_BGRA8888])
        GL_BGRA = 0x80E1;
    else
        GL_BGRA = GL_RGBA;
#endif
[...]

Thanks for posting a code. It's copy - paste bug, it should use COGLESExtensionHandler. Performance of built-in shaders are really bad thats, why I always say that for OGL ES2.0 everyone should prepare own shaders - dedicated for a game requirments, because emulate of fixed pipeline behaviour is just waste of GPU power. Anyway fixed pipeline shaders will be improved a lot in near future, because at now it use rg. 'discard' which is really bad for performance on mobile GPUs.

[ent1ty]

Omg, so that's why! I just checked the COGLES2FixedPipeline.fsh file, there's like 15 if checks there! You need to create a shader for each material, not check the material for EVERY pixel on screen, this is creating a HUGE slowdown, really it's not usable. Just don't use any if's in shaders, it's really bad for performance

[hendu]

Feel free to post a shader that emulates the full fixed pipeline without any ifs. You clearly must be capable of writing one

[Nadro]

"if" based on uniforms and const is cheap for most GPUs (eg. PowerVR arch), just "if" which use value calculated inside a shader is expensive, but we don't use them. The biggest slowdown is caused by discard. Just remove this keyword from a shader and you will see big performance increase in current shader. Switch material on CPU may be more expensive than switch based on if and uniform (depend on CPU + GPU config) and even if we will remove if for branch material, we will use them eg for lights etc. Fixed Pipeline shader isn't good choice, when shaders interface is available. We add support for Fixed Pipeline in ES 2.0 and DX11 just for built-in features compatibility reasons, not performance.

My point was, just don't. Have a separate shader for each material. The way things are now, you check the material type for every pixel getting rendered. Not the most efficient solution, if you ask me


Nadro: are you sure about this? There is only a single discard in the shader - and it's for transparent material. Wouldn't the slowdown only occur when rendering a transparent material?
What discard does, I'm sure you know, it just throws away the current pixel. Usually this improves the fps, not the opposite. Of course, I don't know how's the situation on mobile GPUs. Does it really reduce fps? Do you have a link with some more info on this?

Deferred tiled renderers are quite different to desktop gpus.

[ent1ty]

Thanks, that helps a lot. I tried removing discard from the fixed pipeline shader, this however didn't really help much - 16-17 fps vs the previous 14. So the main problem seems to be somewhere else. Maybe it's incorrectly using dynamic flow control, even though it shouldn't? I know when I removed all the if's(so just rendering everything as a a solid material), the fps went really high - i'm guessing its capped on 60 by android so i can't tell you the exact number.

[Nadro]

We'll back to shaders perf in future. Currently I'm more focus on C++ ES 2.0 code than built-in GLSL, because GLSL may be replaced without any problems by end user, C++ sources not.

[shark_78]

This problem has been solved.

Code: Select all

 
COGLESTexture.cpp:getBestColorFormat: 
"destFormat=ECF_A1R5G5B5;" 
 
OR Invoke:
driver->setTextureCreationFlag(ETCF_ALWAYS_16_BIT,true);

Thanks.

I encounter the same problem when using HTC G14 which also use qualcom ,texture doesn't render.

Does anyone know how to solve this problem?
Thanks in advance.

hi
i changed the code ,but sydney demo's texture is white.
did you meet this problem and reslove it?

Hi,
i have some problem, with android 4.2, irrlicht 1.7.0 beta with emulator.
My Sydney example work without texture binding, but texture was loaded (as you can see from logs)
Someone has solved this problem?
Thanks in advance.

I"d love to see that IRR runs android, but very surprised to see nobody is posting actual screeshots of the phone ? I"d like to see that the phone is running it, so please could someone post this ( my phone isn't working right) instead of cropping the hell out of the edge ? o_0

Thx

You can also just test some real android apps frm the market. I tested Stair dismount some days ago, quite nice. And really nice is also Cubory (lite), a very neat game idea. There are also others, e.g. some Bowling (which didn't work on my old phone, and yet didn't try again) and probably some others.

[ent1ty]

Please, can someone finally go to COGLESTexture.cpp and change on lines 47, 48, 49

Code: Select all

    if (Driver->FeatureAvailable[COGLES2ExtensionHandler::IRR_IMG_texture_format_BGRA8888] ||
        Driver->FeatureAvailable[COGLES2ExtensionHandler::IRR_EXT_texture_format_BGRA8888] ||
        Driver->FeatureAvailable[COGLES2ExtensionHandler::IRR_APPLE_texture_format_BGRA8888])

to

Code: Select all

    if (Driver->FeatureAvailable[COGLES1ExtensionHandler::IRR_IMG_texture_format_BGRA8888] ||
        Driver->FeatureAvailable[COGLES1ExtensionHandler::IRR_EXT_texture_format_BGRA8888] ||
        Driver->FeatureAvailable[COGLES1ExtensionHandler::IRR_APPLE_texture_format_BGRA8888])

It's really annoying to have to do this every time i get the latest revision...


Also i'm not sure why, but at the end of the build process when it tries to copy libIrrlicht.a to lib/Android I always get this error:

Code: Select all

cp obj/local/armeabi/libIrrlicht.a jni/../../../../lib/Android
process_begin: CreateProcess(NULL, cp obj/local/armeabi/libIrrlicht.a jni/../../../../lib/Android, ...) failed.
make (e=2): The system cannot find the file specified.
make: *** [jni/../../../../lib/Android] Error 2

The file itself is OK, i just have to copy it manually
