After a long battle I have some results that may help others.
Got the game to rendering the emulator correctly by building the
geometry using ByteBuffer instead of IntBuffer and ShortBuffer.
I tried converting to the GLSurfaceView and still no luck with the
dropped triangles. I ended up unpacking the indexed arrays into
straight triangles at load time and it works. So now I am using
glDrawArryas instead of glDrawElements. I am pretty sure this is a
driver bug as it's all static geometry and I removed pretty much every
bit of rendering but the static mesh and the triangles drop based on
view point.

Hello,
I am having a problem with what some of the triangles in my static
meshes not being drawn. The static meshes are created once and never
touched again. The class and all the data are marked final. The
triangles disappear based on view point. The code all works on the
BlackBerry and I have checked the data a couple of times. I have
managed to get a missing triangle on the screen and make a save game.
This at least allows me to reload the game with the problem and try
different things.
So I have disabled all 3d rendering except this mesh and the UI. Here
is what I have tried.
- switched to vbo
- switch to interlaced vertex buffers
- tried float instead of fixed.
- removed IntBuffer and used ByteBuffer
- disabled pretty much every state I could just before the rendering.
Oddly enough disabling culling made one of two triangles appear.
Really at a lose here. The game takes about 10min to load on the
emulator and then it renders about half of everything but there are no
errors.
