   I see what you did there.
   And that's awesome.

   Why a cow? I'd have thought a floating pig would be more appropriate for music.

   Like DaliClock, never to be available on the App Store!

   Houston, we have GL spinny-cow. Moooooo. The anticipation of a iPhone utah teapot abounds!

   I want my phone to pretend it's an Apple][ for maximum nerd hilarity.

     Oh yes, that's on the agenda.

     In the meantime you can get your useless Apple II retro-computing fix by ditching powerpoint and giving presentations written in Applesoft BASIC.

   Will there be an Android version?

     Not a chance in hell. It's all written in ANSI C, not Java.

       A sufficiently determined contributor could always try translating from C to JVM bytecode (and presumably translating graphics calls, etc; performance is set to be... suboptimal). (There are a few other products in the C-to-Java space, eg, C2J and Cibyl, but neither seem current.) At a guess it shouldn't be any worse than cross compiling C to JavaScript.

       (Of course I wouldn't suggest that you try this. Your existing GL glue magic is surely sanity sapping enough.)

         I think I'd rather buy an iDevice (and simply snicker and laugh at xscreensaver running on a handheld) than wait for such a thing to appear on my Android phone.

       You can compile C just fine on Android if you're into that kind of thing[1]. http://developer.android.com/sdk/ndk/index.html

       Are you going to release sources Jamie? I'm poking at a BBC Micro emulator trying to get it to run on the Raspberry Pi board & it wants OpenGL but the board only offers OpenGL ES 2.0.

       [1] Possibly for masochistic values of "into".

         Perhaps someone else will be "in to that sort of thing." Source will be out once I get a few more things working.

         Are you sure it only supports OpenGLES 2? My understanding was that everything that supported GLES 2 also supported GLES 1, because GLES 2 is a monumental pain in the ass.

         My code requires GLES 1, currently.

           I have a libEGL.so and a libGLESv2.so (binary only). Do you know what OpenGL extension should I be looking for if the library supports OpenGLESv1?

           • Phil says:

             9 years ago at 1:00 pm

             It's a Broadcom 2835, so the hardware is supposed to support OpenGLES v1 & v2.

             If the function glLightf exists, it supports GLES 1. GLES 2 removed the standard lighting model, among other things.

             If the function glBegin exists, it supports non-ES OpenGL.

               pi@raspberrypi:/opt/vc/lib$ strings libGLESv2.so | grep glBegin
               pi@raspberrypi:/opt/vc/lib$ strings libGLESv2.so | grep glLightf
               glLightf
               glLightfv

               Signs point to yes for GLES 1!

   Will the OpenGL shim API be available separately for other app writers as a revenue-generating cash cow that can cover the costs of putting DaliClck and iXModules in the app store?

    A bouncing cow is perhaps the most compelling argument to own an iPad thus far.
