Unigine in webgl

[anthony.liot]

Without sources and with scons may be will be better if someone of Unigine crew give the different step to follow .

 

[anton.stetz]

in this case, everything works except the file creation main.js. It creates a very small and does not collect  engine.

I'm trying to understand where is a problem

[anthony.liot]

I m looking too the scons and it must be work, when i look your main.js for me there only main.cpp and GLESAppSDL.cpp inside nothing more, like the libs (extern & engine) are not added but i m not sure.

 

[anton.stetz]

Yes, that's right, I'm trying to find the cause.

[anthony.liot]

Hi Anton, i reinstall all the stuff on my Seven, for do some test, and at the end i have the same warning on unresolved symbol.

For me i never found the lib call Unigine_jsd_framework, Unigine_jsd_api and the other .... May be i  am missing something but the problem is here. Inside the evaluation kit, i am not found some .js or .so of Unigine.

 

I succesfully generate the externs lib and the main part but i have no trace of Unigine ....
 

[anton.stetz]

So the problem is not just me. Waiting a response from the unigine team.

Thanks Anthony!

[anton.stetz]

I understand that there is not enough folders. / externs / lib / webgl /, ​​which is described in the file Sconstruct

[binstream]

Full source SDK is required to enable WebGL support.

[anton.stetz]

Very sad. 2 previous version contained a theoretical possibility of creating applications for webGL. After all, it was necessary to add one of the missing folder in the lib ...

[anton.stetz]

Dear unigine team. Maybe for the binary version you add compiled main.js, while the full source code will be able to Compile your own? I'd like to try this technology on real projects. If it turns out - I will be immensely grateful!

[frustum]

The current situation with emscripten is stable. There are no serious problems in the modern browsers. So we will try to add WebGL binary in the upcoming SDK updates.

[anton.stetz]

Thanks, Alexander, you are "best of the best of the best"! :ph34r:

[anthony.liot]

And just for say, with the last Safari on OSX 10.9 the result it's very faster ;)

and i m looking on other new tech call duetto http://allievi.sssup.it/techblog/?p=798

[anthony.liot]

Hi Frustum,

 

Do you recently make some test with Emscripten and WebCL, I was working with an older version of Unigine,

and i recently update both to the last version, and I have some trouble building Unigine. 

Do you have the same trouble ??

Tony

[frustum]

Genius guys from emscripten team declare several functions as defines:

#define isalpha(a) ((((unsigned)(a)|32)-'a') < 26)
#define isdigit(a) (((unsigned)(a)-'0') < 10)

 

It's break compilation because String class has isalpha and isdigit methods...

engine/utils/Str.h:111:14: error: expected member name or ';' after declaration specifiers

                static int isdigit(int code);

                ~~~~~~~~~~ ^

/Users/frustum/Work/Sources/webgl/emscripten/system/include/libc/ctype.h:26:23: note: expanded from macro 'isdigit'

#define isdigit(a) (((unsigned)(a)-'0') < 10)

Comment this defines from emscripten/system/include/libc/ctype.h file to fix:

/*#define isalpha(a) ((((unsigned)(a)|32)-'a') < 26)
#define isdigit(a) (((unsigned)(a)-'0') < 10)
#define islower(a) (((unsigned)(a)-'a') < 26)
#define isupper(a) (((unsigned)(a)-'A') < 26)
#define isprint(a) (((unsigned)(a)-0x20) < 0x5f)
#define isgraph(a) (((unsigned)(a)-0x21) < 0x5e)
*/

[anthony.liot]

Yep I found this problem because Alchemy & Duetto as the exact same problem.

My trouble was more about OpenGLES rendering? But I don't test with your last SDK yet :(

Здравствуйте, Александр!

Следует полагать, вы сейчас работаете над версией unigine для браузера?

Значит ли это, что будет официальная поддержка встраивания в браузеры движка unigine?

 

 

 

[binstream]

There is WebGL version of the engine (at the alpha stage for now), we consider making it an official supported platform later.

At the moment stopping factors are compatibility problems with different browsers and limited availability of WebGL support in them.

[sergey.pozhidaev]

Денис,

А как можно получить версию движка на WebGL для тестирования?

[binstream]

At the moment WebGL version is available for full source licensees only.

Ideas ? Am I doing something wrong ?

Hi, 

Just in case if @unigine crew do some test with webgl, I found some bug recently with Unigine and Emscripten.

First it's when you use thread script, there are some trouble with thread parameter, if you have thread function like InternClass::mythread(InternClass class, string filename), the typeof of the second parameter is InternClass not string.

Second, I patch freetype for test asm_js, but it doesn't work anymore, do you successfully make it work with asm_js ( I make it work but long time ago, not recently ) ??

Third it's the more problematic, When i launch Unigine i receive a lot of OpenGLES error: invalid value. 

 

 

[anthony.liot]

Hi, Just for keep you updated, I successfully build Unigine with ASM_JS enabled. There was a regression inside emscripten, now fix inside the incoming branch.
It's necessary to patch free type because the lib contains some error inside.

In the previous post the loading of the shop was taking 20 sec, now with ASM_JS enabled the loading take 9 sec. It's pretty cool :)

[anthony.liot]

Hi, I know the support of WebGL is deprecated, Anyway, I test the OpenAL part of Unigine.

 

I just make a pull request on emscripten repository for add some missing function :

 

https://github.com/kripken/emscripten/pull/2648

 

I make a little patch of the sound part of Unigine, it's working only for static sound not stream :

https://www.dropbox.com/s/omdsqh6ceh4xjcl/OpenALSoundPatch.zip

 

Enjoy :)
