Twined/rattan/wicker Shell.

Still can’t quite make yarn, yet, so why not twine/rattan/wicker. lolol

for the curious, this is the reference image. :slight_smile:

The shell has some great lines in it!


(Lyle Kroll) #4

Used Rodilius to get the longer lines. I wish I can say there’s now just one flow to render these, but there’s only a loose guide based on my ribbon cable binge. Every render I do uses various blends and techniques (nuance) that make it impossible to share a flow. Some things I just have to say are a company secret. lololol

I can say that without G’MIC, these renders would not exist. G’MIC’s the bomb. :slight_smile:

Sort of reminds me of a brain.


(Lyle Kroll) #6

Better your brain than mine, afre. lolol

Organic Growth Weave

Still experimenting; added Isophotes to the mix. :slight_smile:

@lylejk

Bonjour,

Thank you for sharing the techniques of your creations.
Here is the small G’MIC filter created from your tutorial ‘WickerTute.pdf’.
You can save as user.gmic

Thank you @lylejk and @samj, very nice.


(Lyle Kroll) #10

Sorry for the belated reply, samj; just got back from work 30 minutes ago (work weekend swings). Anyway, I tried to save your file as user.gmic and placed the file in my roaming>gmic folder but G’MIC doesn’t see the preset. Oh well. :slight_smile:


(diego) #11

samj’s preset works when you place it in user.gmic of the portable 2.10rc1 samj’s version


(Lyle Kroll) #12

Saw your post at GIMPChat and replied. Have not installed 2.10 yet; may do so when it’s 2.10.2. lol

:slight_smile:


(samj) #13

@lylejk

Bonjour,

You can update G’MIC, I added this filter in your ‘Testing’ folder.

:o)


(Lyle Kroll) #14

Thanks, samj; preset works, but I see no problem putting this under your samj folder since you did the impressive work of coding my madness (no easy fete). lololol

Results directly from the preset only (with a few slider changes). Impressive. Again, thanks a heap. :slight_smile:


(Lyle Kroll) #15

As a side note, I found that using stencil (low radius) instead of lylejk’s stencil and then follow that by anisotrophic smoothing (fake smudge) gives better results. :slight_smile:


(Lyle Kroll) #16

OK, here’s one that I first pre-rendered using Stencil (around 1 for radius) followed by anisotrophic smoothing. I then fed that result into your preset, samj.

@lylejk

It is always possible to add and modify this filter if you wish.

:o)


(Lyle Kroll) #18

You know I like to asketh for too mucheth, samj. lolol

Regardless, your preset will save me a heck of a lot of time now. Again, thanks a heap. :slight_smile:


(samj) #19

@lylejk

Bonjour,

You can update G’MIC.
The ‘Lylejk stencil’ option is added at the end of the filter parameters.

Filters in your ‘Testing’ folder are on two files :
david_tschumperle.gmic
sylvie_alexandre.gmic

:o)


(Lyle Kroll) #20

Appreciate the continued updates, samj. A bit tired (5.4 mile walk and also cut the grass (well do have a riding mower, but still I have to push to trim; lol). Will play later. :slight_smile:
