    "Les dessous de paillasse" : 8 nouvelles de qui parodient (à peine!) l'absurdité de la recherche scientifique : financement, administration... À lire et à faire tourner!

    If you are really too scared to directly generate the random phases then reinforce all necessary symmetries ensuring a real spectrum, at least you can generate an image/signal with *Gaussian* random iid samples then take the FFT.

    To create a random-phase spectrum of a real image/signal, some people just take the FFT of a (uniform) random image and reset the modulus. Indeed, this generates correlated phases, as shown by looking at the histogram of the iFFT: Not Gaussian => not random phases.

    ...investment leading to collect about 5 petabytes of data to produce kind of a 16x16 pixels image :-p

    Funny fact: for reference, I used TinEye plugin to try to reach the Nasa image from some random website. For the first time, TinEye answered "Your image is too simple to create a unique fingerprint". :-p

    I don't advert each new posts in ( tricks about , , ), but there are a bunch of new ones since last time I did :-) .

    For those interesting in Graph Calculator tricks, I made this blog: ( NB: targeted for university / engineering / research level. Not children :-p )

    Our paper: procedural stochastic textures using only 3 texture fetches from an input example. 20x faster than the fastest previous work.

    NB: a life art/hack consists in finding forms of procrastinations that are indistinguishable from work :-p

    Proceduralism is so cool ! :-) (Only ~25 lines of code, not specially golfed , full realtime ). :

    Beginners (e.g., on ) often ask where to start to learn shaders, or to get more fluent in the maths behind, or more specifically on 3D rendering. I gathered some sampled resources here:

    Why a URL sometime makes tweeter display the teaser image, and sometime not (as for above ) ?

    For I ported the Plouffe spigot algo to ( the marvelous algo directly giving a chosen decimal of Pi -> let get one per pixel ). Alas the result is in hexadecimal. :-)

    Alert ! HostingPics website is closing. Content will be erased in a few months :-( . forums will be impacted. Does Shadertoy dev recommend a solution ? what about shadertoy directly hosting (or caching) pics ? ;-)

    Now, what would be a long-scope image hosting place ?
