    Re: Ptex extension

    About the texture dynamic alloctation... perhaps we won't need it for PTex ( although would be fantastic to have it ).

    We could allocate a BIG texture and "atlas" the PTex faces.

    Re: Ptex extension

    Well, we really need a few things to accelerate Ptex:

    1. Image array support allowing different image sizes.
    2. A texture filtering method using face adjacency.

    3. It supports relatively-new-things like...

    There is a problem with that.... I could have not have a monitor attached to the GPU. I'm using the GPUs for GPGPU, not really to display.

    glFX

    Hello again,

    I see in Khronos a glFX but... where can I download it, pls?
    Does it include shader precompilation, multi passes support and piece/"fragments" linking like DX's fxc?
