 Gamine is an open source 3D game engine for Android devices.  I've
just released version 0.1.  This is still a very early version, so you
probably won't be creating any masterpieces with it just yet, but I'd
very much appreciate any feedback on the overall design and

A few notes on compatibility.  I've written it using the Android 2.0.1
SDK.  I don't know for sure that it won't work with earlier versions,
but I haven't tested it, and I've made no effort to support earlier
versions.  Also, it assumes that certain features of OpenGL ES 1.1 are
supported: texture combiners, automatic mipmap generation, and vertex
buffer objects.  Of course, I really ought to check whether the
appropriate extensions are supported and fall back to other methods if
they aren't, but I don't know if that's necessary.  Does anyone know
of any devices (particularly devices that support Android 2.0 or
later) that do NOT support those features?

1. Is the bad MotionEvent/Touch slowdown stuff actually fixed on first-gen 2.1 updates?

Just wondering if anyone can speak on this yet.  I'd really like to
know what the state of that fix is as 2.1 is rolled out onto first
generation (MSM7200-based) devices.  As it stands, I don't see much of
a problem with touch eating up CPU on the Droid and N1 but those are
much faster phones so I don't think it would be quite as pronounced on
them.  My current 1.6 devices (G1 and Tattoo) cut my framerates in
half during any touch (with the sleep hack, even).  I optimized my new
games so that they would run well-enough (25-40fps) on that hardware
but they have very touch-centric interfaces so won't work well with
that bug.  I talked to a few people who run 2.0/2.1 mods on their G1s
and they said the problem isn't any better.  They still see the big
slowdown.  I tested on my 1.6 emulator vs a 2.1 emulator and there is
a huge improvement.  The 1.6 emulator slows down just like my G1 does
and the 2.1 emulator shows only a tiny bit of slowdown, which is what
I was hoping for.  That's encouraging, but I have yet to see a real
2.1 MSM7200 update in the field so I don't know what to think yet.

Anyone got anything concrete on this?
