LAB#3015 Skybase

Beautiful, unusual and cool swirly texture, and how slow is it?

Lab color has always been one of those useful color spaces when dealing with correcting colors of photographs, sharpness and other details. I made a small utility back several months ago that utilizes Lab. It's relatively simple, but the overall color correction is very precise. Needs more features though as a filter!

Seems like I forgot to talk about this filter. I discussed stuff about it on my Facebook page.

I've been making tiny improvements to it, but I still have an issue rigging some of the things. For example, tilting the water level in specific ways has been proven pretty tricky given how simple the method is. I probably need to add a couple nodes to fix it. (Self-note, don't worry if you don't understand me.)

The filter basically suffers from usability issues. It's not broken, some of the results are just messy when the settings are specifically set.

The neat little thing is that if you feed it a mask, it'll look convincing. This example picture below is a bit rough but you get the point. Of course, the more detail you put into the mask, the better. While it won't find perspective, zdepth or anything advanced, it'll do a pretty "ok" job if you align the horizon line.

The filter itself has limited control, making it slightly easier to just play with the settings rather than getting detailed with them. If you want further control, you might as well use Photoshop in this case

The render times hang around 10 seconds so it's not bad considering there's a detailing, 3-phase sharpen filter applied on the L channel. Overall works pretty fine.

One more.

Mostly made for teaching people.

Otherwise it's just more demo material. Nothing that useful.

3-phase sharpen is just fancy.

[edit] I also have the book. It's mostly sitting around for reference now as much as many of the technical color science books in my home are.

Updated. Fixed displacement, added nice physical lights.

Ah nice! looks good overall
For the top, you could maybe tweak the texture, so that it is round.I used Photoshop´s Polar Coordinates filter for the round bottom of a basket once. Not 100% realistic, but worked in my case. Or make a round version of the filter
And Modo is really nice, i´ve been using it for modeling for a while now and love it.

Well done 3D hat you have done, and I am not so perfectionist and being picky as some have said, and I prefer and like much more the first example than the second, and I personally do not see something bad in how the texture is applied that does not look realistic, I think is very good.

Patterns are always fun.

Some variation on the patterns.

Sooo... it's summer break and I have way too much time open.

The details, unlike my previous versions come out extremely gorgeous.

Just regarding some of the technical aspects of this filter, Mike Blackney's I Dream in EGA has inputs for color controls. Initially these were replaced by lookup components to sample color directly off of the output stream. The unfortunate thing with lookup was that x and y coordinates cannot be randomized per variation, therefore you had to make xy sliders per component or find some other way of deriving specific random constant values.

To save myself from seeing all the ugly, and creating a confusing filter, I just made a small, super basic map script which just samples colors from a given random coordinate to work with the global variation slider. Results are simple: no need for extra XY sliders just to sample a random portion of an image. Betis really helped see through some of the weird things that was happening with the randomseed. Albeit, it might be a known thing!

I made the whole thing into a deployable group component. It just needs color and height input to produce a pixelated output with proper shading. Very handy!

lol spaceray.

Nothing too special here: a quick test of materials in Modo. Render is slightly grainy due to it being "a quick test."
Brick material was exported out of FilterForge. Note: there is no displacement on anything here. The diffuse layer of the filter itself produces a sense of depth as much as the bump maps and normal maps add to it.

Another version!

lol "I do not use or need this kind of beautiful nebulaes,"

Yeah duh! Why would you find use/need for them You do realize all the works and samples here weren't created for you. I have my reasons for making stuff. Anyway, let's not talk about this anymore. Please don't make responses to this statement

Let's talk about art. Art is more important.

It takes 5 to 7 minutes for a 600x600 render with anti-alias. There are 4 modes which lets you render layers of the filter, each for their intended purpose. In my original post, I had these nebulae formations stretched out due to art direction and style. This version was modified to suit more broader needs.

I submitted the rainbow filter thing with the most unimaginative title I can think of. Added several more features. It's a bit slow for a filter from me but it works. [didn't realize it was already online]

Filter utilizes looping to create crazy swirls!

Uberzev's hexagon construction example, rebuilt with modern nodes.

I figured I try something else.

More.

Demo 2.

Note that you can increase complexity as well. I just chose not to for these examples.
