Irrlicht Engine

Btw, i think in OGLES2Driver.cpp we do have missing some check on return result when call glCreateShader() and glCompileShader(). For example for now i found some shaders which fail to compiles on our drivers due to bug in drivers, but, instead of "can't compile shader" we do have error mu...

I just use GL4ES for Irrlicht 1.8.4 port and want to try to get rid of GL4ES in favor of pure OGLES2 port of Irrlicht (to see if there will be speed differences, maybe with Irrlicht version i can get more speed)

For me situation is different, it's pretty always reproducable and stable to see difference (especially 09.meshviewer example, very stable in that terms, i do have 420 vs 220 FPS). Does not matter how offten i run/exit it. That the same happens for me on RadeonHD and RadeonRX cards.

Ok, so .. It mean that OGLES2 in irrlicht is not OGLES2 special code, but emulator of fixed pipeline, just like in GL4ES: https://github.com/ptitSeb/gl4es But what about speed of this emulation ? Is it slower in compare with pure OpenGL on the same hardware ? I.e. on your test machines, the same exa...

Checked other examples and found that also those examples to be 2 times slower in compare with 1.8.4 on SDL device at least: 1. 11.PerPixelLighting also 2 times slower. With 1.8.4 i have there 750 FPS in general, with current trunk i have just 350. 2. 12.TerrainRendering, with 1.8.4 : 1100 FPS, with...

After some tests find out that some shaders fail to compiles on my side due to bugs and unimplemented features in our drivers. So question now is: can i somehow disable some shaders for tests, and still draw things via ogles2, or, whole OGLES2 in Irrlicht can only works with all shaders from the med...

Yeah, can confirm that issues with mouse gone ! Thanks a lot!

Yea, that SDL device i use of course , as i don't have any other for the moment Check plz SDL one as well to compare how it between 1.8.4 and current trunk

@All I do have OS which do not have EGL, but do have OGLES2 and SDL1/2 , so to use OGLES2 driver i had to remove EGL support and use SDL1 one instead. So far, that what i do : 1). in the CirrDeviceSDL.cpp and in COGLES2Driver.cpp all parts with "IContextManager* contextManager" on just &qu...

Yeah, SDL create stuff for sure correctly, i even test it with debug version of SDL, it show that all goes well and as expected, just black screen mean that context creation/attaching/etc fail. We do have in our OGLES2 implementation this function : void aglMakeCurrent(void* context); The context yo...

Ok interesting, i will try then to find out when things start to be different, and maybe that will bring us a clue about

@CuteAlien Maybe give it a shot first with software driver. If that works Do you mean just run example and choose software mode ? If so, that of course works, as it go through sdl+software driver. It just when i use OGLES2 i an see anything.. Will try to play with SIrrlichtCreationParameters::Loggin...

Did you checked exactly 09.MeshViewer, right ?

Well i currently tried to just replace in the CirrDeviceSDL.cpp and in COGLES2Driver.cpp all parts with "IContextManager* contextManager" on just "CIrrDeviceSDL* device", and in CirrDeviceSDL.cpp, in the "createwindow()" do open our ogles2.library. So far all compiles f...

Ok, find out what wrong with build OGLES2 with SDL : CIrrDeviceSDL.cpp: case video::EDT_OGLES2: #if defined(_IRR_COMPILE_WITH_OGLES2_) && defined(_IRR_EMSCRIPTEN_PLATFORM_) { video::SExposedVideoData data; ContextManager = new video::CEGLManager(); ContextManager->initialize(CreationParams, ...
