    I do use this extension. It was alerady included in the first drivers for the 8000 series because AFAIK they use this extension in their OpenGL demos. I'm using it for a particle system completely on the GPU. Check http://3d.benjamin-thaut.de maybe you want to have a look at my sourcecode. The extension is used in feedback.h and feedback.cpp

    Thanks.

    You do not understand me

    I have got lates driver. I see NV_transform_feedback. I have no problem with him. But I do not see EXT version.

    I have got 8600GTS.

    I've checked your link. You write "need NV_transform_feedback "

    I am not crazy. I am asking about exactly EXT_

    Re: EXT_transform_feedback

    Sorry didn't see the EXT part. On nvidias homepage the extension is not listed in the opengl extensions listing. So I don't think they support that extension yet. Furthermore it doesn't make a difference if you use the EXT or NV extension, because the interfave looks the same and ATI doesn't support the extension anyway.

    Dont care.
    As I know there is deffrence between EXT_ and NV_.

    What about ATI(AMD) - it is terrible dream !
    I've been waiting while a year for ATI reaction on EXT_geometry_shaders and ect. ATI dont move in this direction.


    OK. Thanks you

    Re: EXT_transform_feedback

    What do you mean "don't care"?! The difference betwen EXT_ and NV_ is very small. If you want this extension, you can use it on Nvidia card.

    Or get a Mac, they all support EXT_transform_feedback

    Re: EXT_transform_feedback

    I use this extension as well. I'm using it to compute a vector field using a user-defined function in a shader.

    Are you sure? Exactly EXT_ ?
    I am confused
