    How to use the hardware acceleration?

    Hi,

    I have not worked before with OGL ES 1.1 but now i am in the process. I was just wondering how would the device know if my compiled code is based on ES 1.0 or ES 1.1! Is there any preprocessor macro that needs to be set to enable that? I am using N95 btw.

    thanx

    Re: How to use the hardware acceleration?

    Thank you for these.

    They have been really insightful, espicially the second which indicates using the FP with openGL. I shall try this soon.
    However, i still did not find a direct or indirect answer to my question! I am not sure if it slipt when i was reading through

    Hi,

    I agree with you - regarging the Open GL toics there is a guy with nickname "Flame" - he has a lot of good threads here. I'm starting with OpenGL and I found many of them really usefull!

    It doesn't have to know. ES 1.1 is a strict superset of ES 1.0.

    So that means that the code will be compiled with ES 1.1 by default, right?

    Anotehr question, does installing the ES 1.1 plugin for SDK 3rd ed replace teh existing ES binaries and headers, or does it add new files?

    cheers

    Hi.

    I recommend you to use the S60 3rd edition FP1 SDK _without_ the plugin. It has full support for the OpenGL ES 1.0 and 1.1. The only thing you need to worry about, if you care about ES 1.0 support, is to NOT call functions that are present in OpenGL ES 1.1. That is the only thing you need to worry about (even with the "1.1" SDK).

    hhmm...that is tough!! Why not to use the plug in? and how can i uninstall it now? the uninstall option is not supported as mentioned in the releas notes. Also, there is no indication of what is being installed on my machine!!!

    Also if i use ES 1.0 functions like eglCreatePixmapSurface() would that work on N95?

    eglCreatePixmapSurface() function will not work in any HW-accelerated device.

    Only options for HW-accelerated devices (N93,N95) are the screen and if you need an offscreen option, pbuffer.

    Then you can use eglCopyBuffers() to copy them to a native bitmap qith the same size as the pbuffer defined.
