Software News   Software News : MiniGL V1.5. MiniGL gets display lists.
   posted by Hans on 14-Nov-2007 1:33:08 (12264 reads)
I'm pleased to announce that I have updated MiniGL to add display lists, and made a few other improvements too. MiniGL is a 3D API which is compatible to OpenGL(tm). It implements a subset of that API and was designed for speed, therefore it directly interfaces with Warp3D. This also means that there is currently no software mode.

The file is currently in the os4depot upload queue: http://os4depot.net/download.php?file=queue/minigl.lha.

I'd appreciate it if everyone would test this version, particularly developers. Any bug-reports, feature requests, or other comments, just send them to me (tokens of appreciation also accepted, but not necesary ).

Update: a new version (V1.5.1) is available on os4depot.



Changes in this version
-----------------------
- MiniGL now supports display lists
- GL_NORMALIZE support added
- Added a watchdog timer to the smart locking mode (MGL_LOCK_SMART). Audio
should now playback smoothly when running OpenGL applications.
NOTES:
- Only works if "Interrupt=Yes" is set in the Radeon monitor tooltypes
- This has only been tested on a Radeon 9000 card
- This cannot guarantee that audio stuttering won't occur.
- Fixed a bug that would cause only the first quad in a quad-strip to render
(resulting in missing surfaces)
- Fixed flat shading of tri-strips and quad-strips

What about fixing Radeon 8500 3D support?
It can't be impossible as Windows and MorphOS does support these cards.

@Samwel

Fixing Radeon 8500 3D support would require modifying the Warp3D driver for Radeon cards. I only have access to the MiniGL source-code (which is publically available). Added to that, I don't have a Radeon 8500, or the documentation. So it's pretty much impossible for me.

I did some tests with my µA1 here, some demos work well and very smooth, good work!

Some demos have problems, I already sent you a mail with reaper log attached

Excellent, thanks for this new version. I'll try it out with some OpenGL port.

It means that MiniGL will only run on hardware that has working Warp3D drivers. MiniGL will not fallback to a software render.

Nope, it doens't support software render but only hardware accelerated one.

You find demos in the archive of minigl 1.5.

That's in Warp3D not MiniGL, as Hans already pointed out.

For some reason, the same code that works on all other R2xx-based cards does not work on the 8500, I don't know why and and so far didn't get the time to really look at it.

P.S. Good work, Hans

Excellent work!

Does this mean that now MiniGL has everything needed for things like Blender, or is something missing still?

@COBRA

I can't remember exactly, but Blender needed either feedback or selection mode. I think it was feedback, but it might also be that it was just the game engine.

Blender also needs evaluators (glMap*), which should be fairly easy to add though.

Was it before the july update?

Thanks for the comments. Now all those people that were waiting for display lists to port whatever it was that needed it, please start compiling now.

If developers have specific features that they need, please tell me what they are, and I'll have a look at whether I can implement them. I'd also need example source-code so that I can test the feature. Make sure the code compiles using the public SDK (+ fake stubs for the missing OpenGL functions); no Linux code please as I suck at porting and would rather work on other things.

NOTE: I can only implement features that are possible via Warp3D, so features such as direct rendering to textures, is (AFAIK), not possible; you should render to a bitmap, and then use glTexSubImage() to copy it to a texture.

Of course, the MiniGL source-code is available, so you could also try add it yourself. You might want to wait until my changes have been added to the SVN version though.

Hans

One more feature nailed.

Hopefully MiniGL becomes at stage where people can start porting stuff now.

From: the french side

is there a benefit for existing W3D hyperion games ? I was not able to use HW rendering with Q2 using a radeon 7500, only SW rendering was working.

anyway, thanks for your work :
