Today I've released the tenth public TinyGL beta release.

The main focus of this release is implementing support for framebuffer objects. However, in the course of doing that, many other related and unrelated parts of TinyGL have been improved as well, resulting in better OpenGL compliance and more features being implemented.

Please note that the R600 driver is absent from this release, but that it will be readded in a future release once I've updated it to the current TinyGL requirements.

For software developers, please make sure you read the included ReadMe file for important information on using new TinyGL features and fixes.

I'd like to thank everyone who's helped test this release, but especially beworld for his tireless testing and feedback regarding framebuffer objects and my general TinyGL improvements as well as jPV for his very helpful testing in this last week that helped me fix a handful of problems that would otherwise have made it into this release undetected.

Yay!

Thanks so much bigfoot, beworld and jpv! Will try right now.

Wow! Good news!

Great news, thanks bigfoot, beworld and jPV!

At every boot I have the activity indicator of debug 'on'. I do not know what/who is responsible, sdl 2 or tinygl latest releases. So here is the log that I obtain.

I forgot to say that I obtain this debug log only with my macmini. On my amigaone x5000 I do not obtain any debug log.

@Brumiga

Ignore it.

Quote:

This is indeed from the TinyGL update, from MOSSYS:Devs/Monitors/Radeon. It's harmless and you can ignore it. It'll be removed in the next TinyGL update I release.

Thank you bigfoot for your clarification.

Brumiga

Thank you Bigfoot for your hard work. Offcourse also others.

This is a new stage for MorphOS! Thanks a lot bigfoot for this new TinyGL! Many games are more speed and new games with FBO support will be ported!

Thanks a lot to jPV and BeWorld of course too!

For me FBO is not advertised with SDL2.
- I updated TinyGL with TinyGL-Update-2024-09-29.lha
- I calling tglEnableNewExtensions(0) after calling SDL_GL_CreateContext(), and before listing extensions.

but EXT_framebuffer_object is not advertised.

could anyone use FBO with SDL2?

Quote:

Have you update to last SDL2 ?

No need to call tglEnableNewExtensions, SDL2 do it: https://github.com/BeWorld2018/SDL/blob/SDL-2.30.7-release/src/video/morphos/SDL_mosopengl.c#L178

I think you need to force OpenGL 2.0 detection, i see "OpenGL 2.0 not available".. force that. tinygl send you OpenGL 1.2...

After i need source to check and test

Thanks Beworld, my SDL2 was deifinitely outdated.
I updated to SDL-2.30.7, but now i'm getting compile error:

Quote:

ok wiht last version of SDL2, you need to put "-lGL" after -lSDL2

Thanks for your response Beworld!

Actually i had no -lGL in the makefile. If i put it after -lSDL2, the error is the same :/

so... you dont have last TinyGL SDK

Beworld: seems yes, but i ran the latest update... how can i check the installed TinyGL SDK version?

Into last archive: https://tinygl.molsen.co.za/TinyGL-Update-2024-09-29.lha

You need to read "readme"....

Part SDK:

Thanks Beworld!

Now my test project is compiling.

The binary format geometry loader has endian problems, it's easy to modify.

The real problem is the shader compilation:

Image: tinygl4.png

Would be good to know is the max uniform count, and other limits.

Anyway, this TinyGL is promising from now :)

Quote:

Keep in mind. R300 is pretty limited to only 64 instructions. Instructions not natively supported are emulated with multiple instructions as well, which doesn't help either. :)

Multipass is the only way to get around that. If your shader is failing, simplify until it compiles...
