Noise Lab

and again, all of these are ONLY changing the LE.

and we'll make this one the last for the LE changes. this is my favorite:

like i said, not too radical, but each color change brings a slightly new look.

and as we make each new change we get further and further away from the original look:

now, while you're looking at all these, keep in mind what this can mean. you could essentialy have zero input controls in the GUI and only need to change the lighting for some pretty radical changes. or maybe only one or two controls, like one or two for color and the rest in the lighting controls.

and lastly, notice how much we've changed from the original by just changing one color at a time:

I'm glad you didn't take any offense there!

[...] you'd better define 'real world' because i'm getting some very 'real world' with perlin. if you mean man made real world, then i'd agree... mostly.

Ok, I'll get more specific about what I mean by the term 'real-world'.

There is something inherently synthetic about all the noise components, a tell-tale uniformity and regularity that betrays its 'CG-ness'. Breaking this artificiality and hiding the technical artifacts is of great importance for producing the noise-generators that I'm after here. To achieve that real-world (or photorealistic) look, I'd start adding in additional layers of detail to build the chaos and complexity that real-world textures (whether man-made or natural) exhibit.

Theoretically, you could build noise-generators of great complexity that include dozens of layers of detail: dust, dirt, grime, weathering, tear, wear, scratching, cracks, debris, etc. All these would help establish the history of a surface and give it great photorealistic credibility. However, the important aspect to consider is the render performance of a texture filter. We must endeavor to achieve our photorealistic results as economically as possible.

As such, the challenge is to achieve as much photorealism as possible with the least necessary filter complexity. Still - in my book - a noise-generator needs to break 'CG-ness', otherwise I'm just not wow'd. If I see a filter and go 'Whoa, I know it's noise, but how the hell did he/she do that?', then we're talking 'noise lab'!

When combined with some nasty, extra slimy greens and browns, that droopy one would make an excellent sewage tunnel wall.

ok, that helps. i think i'm getting the idea of what you're after now. you want to 'build by noise'. so, this would seem to be a lab of take the loose particles of the universe (noise) and build it up, layer it and mold it into a coherent image sort of on the order of particle chaos into particle order as if a ton of particles came together just right to create something interesting. and particularly so that it doesnt look like it was done on a computer with a noise filter. fair enough. and moreover, i kind of like the idea.

so, let me throw another at you. this is more complex, more layered. it doesnt really look like anything in particular that comes to mind, but all i'm going for on this one is to see if i'm on the right page, in the same ballpark, with what you're after. let me know. i do find this subject interesting. also of note on this one, it kicked my file size up quite a bit and therefore there is more compression to get down to the 250k level to post.

I like your last two samples, especially the second, as you've broken up the regularity quite well with that one. Looks like quicksilver puddles or something. Definitely interesting to look at and worthwhile to explore, IMO.

hehe, we posted almost at the same time.

thanks, dilla. yes, this is very interesting and quite a bit of a different approach to filter making than i'm used to. but, like you said, well worth exploring. i look at my last one there and that is pretty impressive. the background has that roughly the same color quality but varies enough and has a good grain to be convincing, while the molten metal part is clearly defined, especially from the floor and is its own object(s). that's quite remarkable.

carl, it's an open thread. you're always welcome to contribute. in fact, we'd like more input and participation from others. i get some of my best ideas when others chime in on things. dilla here has inspired me in several ways.

and thanks; i think that's one of the best FF images i've ever done.

and by just changing one roughness slider and one color control, i can begin to manipulate the overall effect in some interesting ways.

i'm not quite sure what 'noise relief separation' is, but if you mean those grainy areas and how some are raised in relief against the others, then yeah, i like that too

ok, good

it's an interesting study, steve. i was even toying with noise glass for a bit. actually, i still am. but nothing worthy of note yet.

well, i havent even started to add curves to any of this yet, and that could open a ton of new doors. the glass noise idea was just to see how i could apply what i've learned here so far to other areas. not much yet, but i am reworking one of my early filters for a re-submission.

the first pic on this page should be persude - it reminds me strongly of a brick type I think there called clinker bricks which has glaze patches [ could be wrong name, steve might know ] could you run it through the brick component to see what it looks like [i know it would take a bit more messing than simple plugin ].... only an idea ignore if uninterested

I know it one thing to suggest things and another to get it to work

ok, dilla, i've found a completely new way to use noise. forgive me for being cryptic here for now, but i want to exploit this a bit first this is something quite new; well, new to me. you'll bee things here that you recognize but maybe some you dont. but this opens up a whole new realm of filters for me, with more depth and more effects. quite fascinating.

i'm posting one here to start. this is rough, as i'm still working with all this, but it does show some possibilities. notice the depth of effect and some of the blending and overlays. i just keep being amazed by this program!

lol. no fooling the master

it's funny, i've plugged more things into a 5 color grad and almost never liked it. i just had never thought of plugging EVERYTHING into it. it's a great way to create some pretty diverse images and get some great depth effects.

Strange tree bark?
