Here's a challenge for all to enjoy,
You may draw aught from books to toys.
But, here's the catch, for your entry to pass,
Your artwork must be forged of glass.
Broken, toughened, frosted or slick,
Give your best and craft it quick.

All entries to be submitted by 04 October 2021.

Spread the word!
#inkscapechallenge

Instructions/Information

1. Please read the rules
    
2. If you'd like to post work-in-progress artwork, create a thread in the "Work in Progress" section of the forum, and post your images there. When finished, post the final graphic to this thread.
    
3. This challenge will run from 21 September 2021 - 04 October 2021. There are no winners. These challenges are intended to inspire, and encourage you to share your work.
    
4. You're encouraged to discuss and offer feedback/constructive criticism to others, but please be respectful. We all want to learn and improve, so let's support each other.
    
5. Most importantly, be creative, give your best, and have fun!

I'm looking forward to seeing what you create!

Too many to mention, but I would love to see entries from the following inspiring artists: @doctormo, @Lazur, @mondspeer, @Dillerkind, @m1981, @TylerDurden, @z3z, @brynn, @TimJones, @Polygon, @Boxcutter.

Thanks for starting a new challenge, Pacer! 😊

I'll try my best to join in.

Thank you for the mention! Either it didn't trigger a notification in my in box or it's just buried in a folder automatically.

Anyway, here is something old from 2017:

@Lazur

It's strange that you didn't get notified, but I'm glad you made it to the party. I like the low-poly heart. Do you remember what technique you used? Was it hand drawn? I see from your past uploads that seem you use filters regularly. Are these your own custom filters?

@Pacer yes, they are custom filters. 

This prismatic heart was a simplified version of a previous heart fitted to a winter scenery.

of which I later simplified

Haven't been experimenting much on that matter in the past for years.

@Lazur  I like them all for different reasons.

I think the last one is most glass-like.

I find custom filters to be the most complex part of Inkscape. How would you recommend leaning this? Have you ever written a tutorial on the subject?

You have some excellent work on Deviant Art!

I'd be interested to learn how you created such a realistic wood texture as used in this illustration

Hey, great to have a new challenge. Thank you @pacer for opening it. 

Here is an old test, where I tried a glass of champaign. https://www.deviantart.com/mondspeer/art/Champaign-Glass-Test-484675240
And of course, my avatar is made of glass as well. 

Hopefully I'll come up with something new. 

@pacer Thank you!

Started to write a tutorial series and got to nowhere. Will have to restart that from scratch if ever wanting to  continue with it.  

I'd recommend playing with the demo version of  filterforge to get the grasp of a node-based editor and conceptualise how to achieve a visual outcome from input parameters. 

(Could suggest using blender to create custom shaders but then chances are you'd end up rather sticking with 3D and abandoning 2D vector drawing.)

Then, applying a built-in filter to  an object and checking that in the filter editor, how it was rigged and play with those parameters inside.

After that, it's getting used to how to use the interface in inkscape. 

Patience is an important factor when aiming for such a texture filter. Lot of fine tuning and waiting for the renderer to refresh is required.

Also check @Xav  's rundown on the filter  primitives for reference

Thank you @Lazur, That's very kind of you to go to the trouble. I will check out those resources.

I made this for a digital drawlloween day for beakers.

Hi @sketch_of_life. Nice. Did you create the whole design from scratch? 

@pacer  haha not completely, i pulled the math bit from a google image search. but i made the rest.

@sketch_of_life I like that the liquid has some 'life' to it and some depth. If you want any further feedback, let me know.

@mondspeer I really like the glass, very realistic and plenty of detail.

Hopefully I'll come up with something new. 

I hope you do. I'd be interested to see it.

I startet a new project with glass, but it crashed and seems to be lost. 
So I thought about sharing something older, I think, you'll recognize it. It is about glass ... or something. 

Glass seems to be hard because you have to get the reflections right and the disortion of the background image. 

I seem to run out of space, so I can't upload any more. Sorry. 

You can have a look at it here: https://www.deviantart.com/mondspeer/art/Just-Another-Leaking-Smiley-866862187

I deleted some ot the older uploads. 

So I hope I can show you my entry on "glass". I created everything from scratch, no ressources than my head. :D

Hope you like it. 

 

@mondspeer

I do like it. I especially appreciate the colour and tone choices. Your reflections and the focus on light refraction enhances the illustration. Elegant.

Thank you very much, @pacer

My submission:

Here goes my recent 2 cents:

can also check the svg in the gallery:

https://inkscape.org/~Lazur/%E2%98%85glass-hexagon-loop

@Lazur

Clean and crisp. The interior leaves me imagining what mysterious environment it reflects. Captivating. A very difficult piece to render.

Did you use a filter for the edges and bevels?

@pacer

Thank you!

Tried making it holding some mistic black ink floating around. Will se if I can animate it. Browsers lag big time with such.

No filters were used for the edges besides using screen blending mode on the layers. Those are all gradients.

Only blurring was present on the segments -here is a more fine-tuned version without the blurring and some additional details:

Edit: somehow itis not asclean as it was intended, there is a slight misalignmentin the hexagon segments.

Ok, animating the blob didn't work out, so here is a simplified -but animated-version:

Thank you all for taking part in the challenge. Some excellent pieces indeed!

I would love to see each of you again in the next challenge, which is now in motion:

Made some new glass loops -in the shape of an endless knot.  

Attaching them here as well, although it's a bit late for this challenge but they are still related.
