Thanks for the response so far!!!

1000000 - just a number to make it clear that I want to sort big lists.

I should have been more precise - in fact I want to sort pixel values, a huge amount of pixel values. I´ve done this already with sort from zexy (with arrays) and it worked pretty well. But it´s either the original or the sorted result. So a animation or a warp or at least 75% between would be nice.
...

you can have 2 array : the unsorted, and the sorted. then interpolate between 2.

I work with images >5k resolution (and tiling)  :-)

this is still a lot for real time in the CPU.
but if you find a way to store the 2 array in the GPU (using texture), and interpolate with a shader, then you will be fine.

btw. what is the meaning of "invision"???

i think Iohannes ask what is a 75% sorted list.

        you can multiply lists component wise check in (listabs ) in help browser

        multiply by a fraction then multiply with the goal values

    for large list, i suggest using array and iem_tab

    for a fade between A and B, x being the fade factor for 0 to 1, the fade would be :
    A * (1-x) + B * x

        you should look egregore by chdh (on this list ) for morphing
        and they have a live in one week on the net using the patch

    thanks for the reminder ;-)

    we don't have "lot's" of fade involve in egregore, but if you like lot's of particles moving, you should see the next chdh  performance : "morphist"
    (2 live in Paris next month, see chdh.net <http://chdh.net> for more informations)


        1000000 is hard to handle...

    it's more square than pixel in a 1024x768 screen!
    but with a good computer, 100 000 moving dots should not be a problem.

                e.g. what's 75% between "1 6 8 4 3" and "1 3 4 6 8"


            Yes, that´s the question. I am thinking of e.g. 1000000 squares [GEM] fading
            from random position to sorted postition.

            How can I fade lists?

            Thanks,

            Rainer

                    Hi,

                    I´m just playing with the sort object from zexy lib, sorting a bunch of
                    floats. I wonder if there is a way to fade or morph(?) from unsorted to
                    sorted state?


                how do you invision that?
                e.g. what's 75% between "1 6 8 4 3" and "1 3 4 6 8"

                how is your result different from a generic fade between two lists of
                equal lengths?
