Hi DzzD,

Tons of thanks for your post.


You are kidding me right ? this noise implementation is a gem.
I would have appreciate using it extensively in-line but you know how it is... I don't have time to figure out if I should compute all this mess on the fly or use a raster to leave hand for therefore other basic stuff.

I finally use a pre-rendered noise map for my sh..(because I need / was tempted by more tons of octaves-based visual result... ( ).

I am still planning to use your snippet to complete all this with small in-line extra layers(multiple ways, starfield, extra noise when we are close, etc...).


Much thanks for your input, I have to admit I am testing this cool stuff with c++(ported, for sure, in no time - one or two lines  - thx to your clean coding).
I am still a bit lost with fully reading your optimizations but I like the style, specifically as it is the fastest noise I found so far !


Wow, this is your job or maybe mine with few month(S) more training on this(need time to understand how to translate this "clean" on various different vector units microcode- spus, gpus... man, tons of exciting efforts ahead - at least for me...).

I am definitely giving it a deeper shot asap !

Thanks again,
ok

Hi DzzD,

Your noise func is super-fast, thx for that ! (could be also easily simdized, yum!).

I needed a seamless xy result so I used your multiplication trick to get the pseudo 4D noise and feed it with two circle coordinates. This is also working a treat !

Probably silly question :
Do you think that fake 4D is overkilling / do you have a simpler solution to get your 2D perlin signal tileable ?

The tiling is working cool with your fake 4D trick for now, but I get far more pronounced bi-cubic artefacts with this multiplication trick...

Do you think quintic interpolation could solve this ?

Much thanks again !
