    implemtations available

    Are there any optimized software implementations available that run on PocketPC? If so, where, and which are best?

    Re: implemtations available

    klimt is the best choice
    search klimt on sourceforge.net

    Re: implemtations available

    Thanks, but I should have been more specific. We have a closed-source scene graph that we would like to put on top of it, so GPL doesn't work for us.

    So we need something LGPL, BSD, commercial, or something similar.

    Klimt is not complete OGL-ES implementation, you had better check before you decide

    Re: implemtations available

    You can also try Vincent. It started out of a discussion with Daniel on how to clean up the klimt architecture and how to make it independent of PocketKnife. Comes with a BSD license.

    Re: implemtations available

    yes, klimt is not a complete OGL-ES implementation. if you need full compliance (whatever you'd need that for), you should get a licensed version.

    an advantage of klimt is that it implements more than just a part of OGL-ES. large OpenGL compliant toolkits, such as Coin or AMIRE run fine on top of it...

    Re: implemtations available

    Hi
    OpenGL ES support more than Klimt
    but how to write a simple appalication use OpenGL ES for PocketPC, Smartphone..
    I have download the implementations of OpenGL ES -- gles-1.0c.gz on this Website , but I am sorry that After I unpacked it I don't know how way to use it . Could anyone can help me ?

    How to fix it

    Re: implemtations available

    The reference implementation you downloaded is just a wrapper around a full OpenGL implementation. It's mostly for experimenting, but is not really useful on a mobile device. If you want to spend money, I'd choose Hybrid's implementation, otherwise try one of the two OSS projects mentioned above. I guess you can contact either Daniel (for Klimt) or myself (for Vincent) if you have problems getting started.

    Cheers,
    Hans-Martin

    Re: implemtations available

    To my knowledge there are currently only three public OpenGL|ES implementations (not counting the reference-wrapper):

    - Hybrid's implementation which is a high-speed, high-quality but commerical implementation and at the moment the only one that has full and official spec conformance.

    - Vincent (OGLES) which is open source under a very open license. It uses run-time code generation (as also Hybrid's implementation does) and is therefore well prepared for upcoming pixel shaders. Unfortunately this means that it only runs on ARM processors.

    - Klimt which is open source under the GPL license. It is fully written in C++ and therefore very portable. Currently implementations exist for Windows, WindowsCE, PocketPC, Smartphone, Linux on Desktop, Linux on iPAQ, Linux on Sharp Zaurus. Upcoming platforms are SymbianOS and PalmOS. Additionally to the other two implementations is can also run (many) OpenGL applications or libraries. *hint,hint*

    As Hans-Martin already wrote: contact us if you are interested or need help...

    bye,
    Daniel
