Well, with that special hubris that comes just before you realize you did something super stupid:
"no, the code is PERFECT!" :-) For some reason, I found some other threads talking about this (sort of) AFTER making my post (I looked first, honest!), but I guess those were sort of off-topic comments, so maybe a new post just for this is not a huge sin. I should mention I do not have the issue in the emulator (when I can stomach running at 4 fps), just on my Droid. (and maybe not on the Eris, the only other test phone I have), so this might be a Droid- specific issue. So far, I have only noticed it on my terrain, though the same code is used to render other meshes in the game (the poseable-skeleton characters, for example). It's possible it happens there as well and I just haven't noticed yet (I mean, if it's a Droid bug, I would think it would have some probability of happening on any of my meshes). But the terrain mesh has fairly large triangles, which is why I am willing to suspect a math overflow issue. Still, lots of nearby triangles, sharing the same verts, will be non-problematic. I guess the most LIKELY explanation would be the short index buffer. something like the first or last entry in the list, maybe. I lied a little implying there was just one terrain mesh, when really the full terrain is tiled with multiple meshes, and I haven't tried using goofy texturing to help identify if this is always a particular corner of such a mesh (i.e. first/last triangle). I guess I will try that now. But to answer your question, I pass the gl check stuff when I turn it on. And again, all the buffers are completely static, so their content should not be flakily changing. If I had bad numbers in the buffers, I would expect the problem to be pretty constant. - Dan On Jun 13, 1:21 pm, Frank Weiss <fewe...@gmail.com> wrote: > I'm no GL expert by far, but is there possibly a debug or logging mode > which might expose a calculation or data error? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
