Suggest a new filter.

Hi Romaq,

Ok, in any case, I did get this to the point where it at least seems to be correct based on the data you gave. Here is the output:

That's exactly it! Yeah, a Sculpty is a texture that works somewhat like a normal map, only where a normal map applies to a projection of a surface polygon to add/ subtract to the base polygon shape, a sculpty applies to a single point in space create the appearance of a mesh. Sculptys do have limitations that make true mesh WAY better, but a sculpty is *cheap*: it's just an image mapped to a point in space.

Your filter works perfectly! Now the thing for me to do would be to use this as a base to create a texture that both deforms this base mesh and (using your switch) creates the surface texture map that gets applied to the sculpty. The deformations to the mesh map and the texture will be off the same noise data.

Thanks for the help! I love your Planetary Noise Generator filter too, and I've used it to create a few things. I just wish there was a means to collapse all of your transformations into a 'black-box' where I give it two noise components (or possibly one stretched?) as inputs and have the result deformed for 'planetary mapping'.

Anyway, I'll work on something using what you have given me. I know of some people (Torley being one of them) who may be interested in texture that create both the sculpty map and a matching surface map for things in Second Life.

Excellent! I didn't think to take that approach. The end goal I had was to have the sculpty rotate about the axis, say clockwise once every 10 seconds, then have a texture animated rotation counter-clockwise once every 9.9 seconds. The intent is to have a liquid surface with ripples. Your solution may be the better one for the purpose, I'll have to kick it around to see.

I hope there is an image above that is a sculpty sphere. I'd love to get some filters that create both, say a 'rock texture' as well as the sculpty map that the texture applies to. That way it would be trivial to generate a sculpty rock and the texture map at the same time from the same noise data. Your snippet shows me how to create a switch for 'texture map' vs 'sculpty map' without having to start with a new image size for scaling.

I'll have to see what can be done with the resources at hand.

I enjoy this dialog, but perhaps we should start a Sculpty Discussion thread to keep this out of "Suggest a New Filter."

The point of rotating in one direction and animating a rotation in the other would be to have things 'mostly' sit still, except the deformations would cause a semi-random looping wobble, appearing something like waves and caustics.

EDIT: I started such a thread here, and if those who have contributed to the discussion would please repost their work there, that will get us out of everyone else's hair and make it easier to find.

Of particular use is the filter by ThreeDee that creates a four-corner circle. Mongoose King countered with a Sculpt Frame Trimmer. A good demo would be the upload of a filter that creates the four-corner circle and has a slider for XY noise (red and green channel by the same percent) and Z noise (noise on the Z plan separately). I can see the filter accepting an input image, then the Z axis noise would brighten/ darken the produced image as if the height-map were applied to it. Toggle a filter control, and instead you get the 32 x 32 sculpty, though of course the 'sculpty' would be the same resolution of the image, but would be ok if reduced to 32 x 32. I'm confident I can create this based upon the work already presented here in this thread, but I don't want to steal thunder from either ThreeDee or Mongoose King. Mongoose King also came up with a different approach to the problem by hiding the corners of the sculpty to make it round. Whichever way you slice it, please consider reposting your wonderful filter examples on the thread, and perhaps we can get the attention of others who would have an interest in using FilterForge for sculpty mapping.

Well you got me started with the Diamond Square Algorithm. It sounds doable with the lua scripting and there are some copyrighted examples floating on the web. Although not sure if it'll be just plug-n-play. I guess I should wait about that.

Here's my interpretation of the holes/blobs effect...





The blobs are a bit grid-like but I think I nailed the distortion formula which stumped me for a bit...

Cool, Uber. Fun to experiment with.

Woah I bet the effect could totally be reversed for some wicked water drops on a surface. )) Mercury would look sick

Nice and very good suggestion for a FF filter, although as you say is difficult to make and get a good effect like this

Amazing kirlian photography

Also can be like electrifying things



could be like the Xenofex electrify filter for Photoshop

Similarly....

and when you derive points from it... you get

And it takes code to do it efficiently.

Least the steel nest is a bit easier to accomplish.

Frequency Separation

There is a lot of interest among retouchers in separating images into high and low frequencis, retouching the high frequencies (where the blemishes live)while preserving skin pores, retouching the low frequencies (where broad discoloration lives) and then recombining them into a finished retouched photo.

A long thread devoted to this topic

Here is an example of someone digitally ironing the wrinkles in a suit without disturbing the detailed woven pattern:


Has anyone done any FF work along these lines? I guess it would be more of a two filter set, or a single filter that outputs two intermediate images, the high and the low.

When will this be?

So I like that style soho put up. Here's something I made roughly based on what I had.... It's not exact... kinda hard to get nice curves and stuff... hehe

EIther way it's a start! I'll put more examples on LAB#3015 (thread in gallery)

We can get "orientation" pretty easily but not depth without user input. We can also just deal with luminance maps and attempt to get the effect. I mean, I feel like this stuff starts becoming all about if we can make the effect using what we have. Of course the full effect can be achieved in 3D as described. But because we're limited in the data set we'd have to come up with work arounds for achieving a similar look. Things get cooler that way.

Here's another attempt using basic luminance maps.

I like what Carl's doing better.

I don't think it was done in After Effects in part because the effect of it is textured on the surface of objects. It's more likely either a shader or a render style developed in the software they were using. AE was probably used to add additional detail and composite but After Effects typically can't do that without being programmed to.

Carl and Skybase, love your examples.

As I say mine was just a quick mod of Wicked Weave [ all the structure was already there ], to get those long continuos lines is the trick, but I don't think impossible.

I'd love to see a filter with classic Greek key border patterns. I've searched through FF and can't find any. Extra bonus points if they can be wrapped around shapes.

If such a filter already exists and I just missed it, I'd be grateful if you could point me in the direction!

Well I'd be happy with just some flexible basic Greek Key patterns

Here are a bunch of examples:
