Noise Lab

When blending three or more noises, working with different blend modes on each single blend helps give the surface much more variety, and may yield surprising effects.

In this example I used three noises and blended with lighten and difference blend modes:

Chiseled

ok, here's one that reminds me of fossils. i had to turn the anti-aliasing back on for this one. was getting too much noise.

Exactly!

cool beans, dilla

great stuff here, dilla! thank you

yeah, i thought so too (and thanks), but this one just came up and floored me!

Taking it a step further... three noises blended, with a noise-mapped profile curve!

Techno-Fungoid

ok, forgive me, but i did a quick revision of shark tank and unplugged the condensation and scratch parts. i wanted a clear view. and used that last 'coral' as the import to the filter and came up with this:

A variation on the last one...

ah well, the Simpsons are on. gonna run

Asteroid!

Chiseled Stone

Whereas 'bump mapping' simulates surface deformation... 'displacement mapping' actually affects the surface geometry.

Hey dilla... what software are you using for these renders? Looks pretty high-end...

ok, so it is like 2d displacement mapping where you warp the texture to the 2d surface based on the 2d image's height map. so, in 3d it would be the same thing.

lol, dilla. that 'clicky' takes me to a wiki which just confuses me further. i dont know all those terms, so it raises 16 more questions and answers very little for me. i am trying to learn all those terms, but one at a time, please the problem with those definitions in that wiki is that if you define a term with other terms that are unknown, you cant define (for yourself) the original term unless you look up and define those other terms being used to define the first one. and therein lies the rub. i do know what bump maps are, but i only sort of know...sort of, what a normal map is. i do understand that it seems to have to do with mapping for light and shadow and that it seems to produce better results than a simple bump map, but that's about it. how and why it works and where you would use it,.... no clue.

in other words, i need the simple dictionary

and i'll state this again. you really get what the environment lighting does on these. i get some really nice lighting changes between the different environments and in moving the environments around. really shows it up!

so, thank you for this

Not only that, but doing the blend exercises you'll also start to grasp how to compose meaningful heightmaps and functional normal maps for your other filters.

Another one to ponder for your experiments:

Take a pattern like this one here...

In few days I upload an filter product of my experiments with noises.
The name's filter is Black Hole.

hopefully this is more of what your looking for in this thread....

Hehe. Yes, much more. I was just teasing you to go 'more complex'. Getting off the well-travelled paths is what we should do...

Humm... welll.. no.. errrr... mmmmm..
Is the other... the other black hole...

ah, i like that last one.

Interesting...

Looks like something very disgusting is slowly running down that plaster.

sort of looks like a crater from above.
