thanks Kraellin for putting this thread and I agree with you that there is a lot of interesting and useful stuff in this thread, although I know now and have promised that I will not give anymore any thanks in any old thread, so this is only as an answer to your email and not to bump this thread, and will not keep doing it

IS curious that is was very active until 2013 and then there has not been addded anything else in these 3 last years, a pity

I've submitted a new filter called "Mars Lander 1xx" to the library. hopefully, it will show up soon. that filter was a result of this thread and so I'm posting a picture here from that filter. if you get the filter, open it up and look at the use of the perlin noise component. that is one of the most versatile components we have.

A few things to note here. I believe studies have shown that humans are biased to interpret 2d images of surfaces as convex. I would imagine convex surfaces are more common in nature, leading to evolutionary bias. In nature, the sun almost always shines from above, so our brains have harder time figuring out surfaces lit from sides or from below.

If this particular image is interpreted as convex (as we are biased to do), the lowest points of the surface (lines between the overlapping spheres) should be darker as less light would reach these occluded areas. They are however the brightest parts of the image, leading to more confusion in the brain. Seeing the surface as concave seems more physically correct to me, but it's hard to fight the bias.

Adding more realistic lighting would probably help our brains make a better guess here - ambient occlusion and hard shadows. I guess there's no perfect solution, other than having actual depth information.

Still playing catchup in the Forums, but this thread's been worth the read! Every example shown would immediately go into my download queue and into my surfacing pipeline if they were in the Library (apologies if they are, I just don't know what any of them are called, and I don't remember seeing them the last time I paged through the entire thing!).

Seriously, people, submit the dang things already! (Or at least share WIP filters?)

Heh.

That's pretty much why I got World Machine in the first place.

The work shown in this thread is inspiring, though. I'm far from opposed to learning and experimenting on my own, but I'm not one to reinvent the wheel. Not when I'm looking at a Ferrari! After all, who can find the time to be the best at everything? It'll be some time before I can recreate what someone else has done masterfully. As much as I understand how much an artist puts of him/her self into a filter, and appreciate the need to conserve their uniqueness, I'm also one of those who lean best by taking things apart.

So, yeah, big fan of sharing and not too shy to nudge. I'm not trying to sign my name on anything, though. Perish the thought.

Counting this one, the last five posts are really off topic. They can cheerfully be deleted, and we can go back to talking about interesting noise.

Agreed?

Hmmm...

Bark or rock?

This thread has already more than 205.000 views amd I understand it because is really very interesting and useful and would be good that it could be continue increasing and add more things

I will try myself to put something related to noise that I am experimenting and testing

j'aime beaucoup ta texture Racine et la dernière aussi qui me fait penser a de l'écorce d'arbre.

Here's another texture filter I've been working on for about a week.

Thanx Ghislaine, I appreciate the comment.

Here's a filter I've been working on for my Exterior Wall Decorations series.

Here's a couple of aerial shots of the dead sea. I think they would make some fine filters.
