I can't get any 3d visible on the screen anymore after updating to latest devkitARM and libnds. Same goes with included NeHe examples (tried lesson05 and lesson06) - just blank screen everywhere. Checked the update list of what has been changed but can't see how the gabebear updates could have anything to do with this...

there are currently more problems with the new libnds, better we wait for the updated examples
my problem: when i recompile the watch example, it doesn't work correct, it seems to be that the ipc data is not queried correct in the current build, so the clock is set to 0:0:0 am

Same here, I have LOTS of strange 3D-related bugs (no matter what I try/set). glPerspective and glOrtho are very f'ed up and perhaps even other things.
Also, I get different visual output in no$gba versus the DS itself.

also when using the "old" examples, especially demos with graphical output using the gl*-functions, the ds screen flashes

Reverting back to libnds-20060719 did the trick for now. It seems to work also together with devkit ARM r20, guess I'll go for that kind of mixed setup until the libnds and/or the examples get updated.

is libfat-20070127-nds compatible with this release?

devkitARM r20 is a prerequisite of libfat-20070127

Actually the clock is always set to 0:0:0 and has been for a while. The way the RTC was handled originally was quite wrong and was removed but hasn't yet been replaced with something sensible. This is related to the default ARM7 core not libnds.

You'll probably have some problems using the default arm7 core doing that. It might be worth giving CVS libnds & examples a shot, we currently have a new slave^D^D^D^D^Ddeveloper sorting out some problems with the gl code.
I'll be rolling a new release shortly when that stabilises.

Thanks! Updated & compiled the CVS libnds, and now I got 3d back on the screen again. There's still some small graphical glitches - for example textured cube at nehe/lesson06 has visible texture borders, whereas earlier there was no borders at all. Well, Gabebear said another patch is on the way to fix the examples.

Lucky you.. I've also updated everything from CVS and the examples are compilable again. Unfortunately there is still no 3D output on any screen.. Anything else I need to change?
#119524 - simonjhall - Sat Feb 24, 2007 12:28 am
My 3D was invisible on both my programs until I read the release notes - gluPerspective and glOrtho no longer set the current matrix to the projection matrix (as they're not necessarily viewport-fiddling functions).
A few quick calls to glMatrixMode fixed all my 3D problems.

Is this now working for everybody? I still can't get anything on the screen with both examples and libnds in the newest version from CVS. Everything compiles fine, though, but nothing's visible.. Are there additional fixes necessary in the examples code?

Yes, everything is working fine since one month ago. Make sure you're having the latest examples also, not just updated libnds. Also, 3d apps don't work generally too well (if at all) on emulators, test if it works on the hardware.

Compared to r19, it just needs an extra

| glMatrixMode(GL_PROJECTION); |

that fixed it for me.[/code]
