Thank's!

The next part will be adding appropriate colors and hue values to this grid series. How 256 levels can be split to 1-36 or to 360 even steps... and that the rgb space used hardly matches the impression of the human eye.

Your recent posts are all amazing, Lazur !!

Its a pity you are dropping these pieces on our heads without much comment.
They may look simple on a quick glance, but they are all complex and full of technical know how.

They may look simple but in reality it is alot of time and effort.
Yet in the drawing process to speed things up the number of unnecessary steps needs to be kept as low as possible.
That is why when I'm trying to make a tutorial there are small parts that won't look logical between two steps.

Would need to break it down to so small parts that alone doesn't make much sense.

But you are right, will try my best at it sometime. Should list all the "articles to be written".

  • vector vs. raster format
  • a better take on anti-aliasing then the previous
  • continuous squiggle part 1...x
    (building up from simple quadratic sectors, adding overlapping, redrawing the whole thing on a grid, adding a pattern, adding a gradient, ect.)
  • drawing a trefoil knot
  • drawing a knot with overlapping
  • different ways to draw the same overlapping knot
  • drawing a conic tile
  • drawing a conic tile with overlapping
  • using clipping, grouping and cloning to draw a kaleidoscope-like image
  • drawing a snowflake with the previous method
  • drawing a snowflake the original way (I know, there is already two tutorials for that)
  • drawing a conic gradient of separate tiles, with linear gradients


What else? How to draw a logarythmic spiral with golden ratio, with overlapping tiles and bent gradient and...
Those vector images are all public domain, guess hardly anyone would follow how to fish when they can have unlimited fish. That "plus" is more related to mathematics than simple tricks in the process.

Im fully aware of that.

What is think is missing in this forum at the moment is the community effort.
I appreciate your mission to write interesting tutorials, but its all so much more fun when we can learn new things as a group effort.

That's something I'm trying to provide at Inkscape Community, with the challenges and contests. The challenges are more for learning and skill building, but until we get more participants the contests really do the same thing. The problem is that it's only me and Lazur who participate. As soon as we can get at least a 3rd participant, then we'll use the Ratings in the gallery to choose the image for the front page of the gallery. (I make a special album in the gallery for each contest).

We used to do that here, using the Competition board, but I think some people were scared away with the word "competition". Plus some of the more enthusiastic participants haven't been around for quite some time.

I have to admit im not overly excited by these kind of challenges, because i dont enjoy producing "art" in a given frame, that is out of my interest-zone.
Im doing plenty of stuff at home. 90% of that never sees the light of day.

Also im hardly learning something new by taking a challenge/contest.
Thats just practice.
Might be different, when the topics are different.

For example, there are these "hipster"-logos out there, which are (were) very much in fashion at the moment.

But still, theres is very little to learn, unless it involves some new techniques.

Also i think a challenge is something, when one person posts an effect and the community tries to develop techniques to achieve this effect.

There's no timeframe for the challenges and contests at IC. Anyone can participate at any time. I'm not good with deadlines either.

Only if you use the same techniques that you always use. But what if you try to draw it in a different way than you've ever tried before? No one can know what everyone needs or wants to learn next. You have to add some of your own imagination to the challenge.

A challenge could easily be just what you describe. Show an image, and the challenge is to try and recreate it. We haven't done it before, because I just never thought of it. But it sounds fun, and it's a good way to learn new things. I'm always open to new ideas -- both with using Inkscape, and my forum :D We can do it if you want. Would you like to choose an image?

Or what about a challenge that tells you what kind of tool or technique to use? If you've never used that technique before, you learn something new. Although if you already know that technique, you might not learn much. But if you already know that technique, you could just say 'that's boring, I want to try it this other way', and then do that. These challenges are nothing formal or literal. They're just ideas or opportunities that you can use however you want.

For example, the decorated egg challenge. If that's boring for you, decorate your egg in a goth style, or halloween. (oooh, this would be a good time for a Halloween challenge! Do people give out hard boiled, decorated eggs to trick-or-treaters?) You have to add some imagination of your own!

Getting back to the grids.

Image

This one was drawn without overlapping, so gaps appearing here and there. Only one gradient fill was used for the spectrum.
Thinking it over, as the first step of the gradient is the exact same of the last one (0 and 255 hue values), it would take a next step on the right for a better palette.

But as the gradient can be changed too, with "non-continous" gradients it can produce a stepped look well.
For example:
Image


Edit:

Now with overlapping/without rendering gaps.

2222th post in the work in progress section.

Seems appropriate for grids based on 2pow.

Here comes 2*2*2*2 images.

Drawn both with rectangle shaped objects next to eachother and with overlapping.

Previous post got quite good on the organizing.

Let's try things in that vein, from the start.
Click on the "thumbnails" for the svg source.

(Something is certainly wrong with image embedding that I cannot help. No matter those images are of the same size, same height/width ratio, chose to generate same wide thumbnails, they appear in random sizes here so decided to use the original thumbnails of 2400 px width that got scaled automatically by the forum on these portrait format images.)

It's very relaxing to set this page to auto-scroll up and down over and over after a while when you look away the real world also breaks up into stepped gradients that smooth out slowly...
Your mind is what you think it is.

Amacing! I love the grey scales even if all of them are a bit hard for me to look at due to my nystagmus. Great work!

Things might get real trippy though this time it wasn't intentional.

These started out as a "journey" to find colours with even steps in tone from eachother yet the rgb inkscape is capable is lacking.


The yellow, cyan and magenta colours are much brighter than the reds, greens and blues, and probably if the brightness is corrected, the saturation would end up being uneven.

Same applies to the greys. The linear interpolation might function well (mathematically) between tone values in general (if used as a masking object) but a simple white to black gradient would need a bit of gamma correction.

Just a quick example on correcting the tone levels on the "spectrum" gradient:

Image

Note that the values at the bottom 1/3 are looking the most balanced.

first one is always from separate rectangles next to eachother, every second one is overlapped.

Keeping things more consistent, more than half of the previous series was missing.

Hmm need to get back to that "colour theory" concept sometime.

Just finished recently this one:
Image

Based on the Fibonacci spiral proportions, using gradient meshes and new blending modes.
Also the background texture is pulled off straight from this pack.

The proportions of that Fibonacci spiral, based on the golden rectangle doesn't look so natural.
A quick search lead to this article, discussing a much better one.

After more research I came up with these:
Image.

Will try building up shells on them sometime -and figure out a construction that really eliminates the anti-aliasing gap artifacts.
To me it seems the cairo renderer brings out it even more than before.

Now, the golden spiral/Fibonacci spiral recreated from tiles at 1 gon turns:

Image

Also, with each tile having a "flat" fill it adds up to a conic gradient look -technically those are the same linear gradient fills, so you can edit the gradient definitions easily for changing the colours.

This one is currently my best go at overlapping the tiles for such a spiral. It shouldn't produce rendering gaps at any zoom levels.
So no more of that slight interference pattern at the centre as before.
