Amiga Events : MiniGL V1.5. MiniGL gets display lists.

Amiga Events

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.

Edit: New version uploaded

http://os4depot.net/index.php?functio ... river/graphics/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 necessary ).

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

That's me screwed - OS4 won't boot if I add that.

Why the change? Old version is perfectly happy without it.

It will still work with Interrupt=No. However, I can't do anything about the stuttering audio with interrupts set to no. Some programs cause the audio to stutter, others don't.

Excellent! Now to just get a working cross compiler!

(Yes, I'm still working on it. Mostly a lack of time).

That's OK - the text in the article is misleading in that case. It should say that there may be audio problems with interupt=no, not that it won't work at all.

The indentation disappeared and I didn't notice. The original version had the "NOTES:" section indented so that it was clear that this was related to the audio stuttering.

@all

I've uploaded a new version that fixes a few bugs (including one that locks up ScreenBlankerPrefs after previewing an OpenGL blanker) and added changes provided by Steen Lund.

Please download the new version.

If some moderator could edit the news item (I can't seem to) to inform people of the new version, that would be appreciated.
