Episode 174: Wilber in a Can

Download the Video! (21:45 43.3MB)

To get something festive to drink over the holidays I have ordered a special MTG-Beer from a brewery. It’s finest Pils in a can with Wilber on it! (Why a can and not a bottle – there is no “Make a Bottle Filter” in GIMP.)

In this episode I explore the Map to Object filter. It can render an image on a plane, a box, a sphere and a cylinder. The default dimensions of the cylinder are that of a beer can. Quite significant insight into the world of programmers. (BTW, the box preset is a cube, not a pizza box…..)

The image used in the show is stolen from Steve Czajka.

But before that is a look back onto the last show. Saul Goode shows a much easier way to generate patterns with the clipboard and I explain how I got the dots of different sizes in the blog image.

For all of you a happy holiday!

I hope to be back still in this year, so I’ll keep the new year wishes for later. As a distraction the 28c3 is coming up 10 minutes away from my home. I got no tickets but hope to get in there at night and watch some stream on the day.

Hand Craft and Digital Art – Custom Calligraphy for Meet the GIMP

Steve Czajka has made a custom calligraphy for this site – and he has documented the process in a well written tutorial and a video.

Have a look!

The banner on top is also (you may have guessed it πŸ˜‰ ) from him. It will be there for the holidays. After New Year the rotation of your images will start again.

I wish you all a happy holiday and a good new year! (And there will be at least one more show in 2011…. πŸ™‚ )

 

Episode 173: Lots of Dots

Download the Video! (14:10 26.9MB)

Meet the GIMP is on Youtube! Mike AKA Eppic has started this channel and is uploading all the old episodes. Thank You!

I need some dot patterns for a project with MoirΓ©. And so this episode is deveted to building dot patterns out of a grid without grid lines. Misterious? Have a look at the video!

The video ends a bit abrupt. Cinelerra went on strike with the last part of the footage. So some stuff is left as an exercise for you!

BTW, I am back. πŸ˜‰

In this video I’ll review the “GIMP 2.6 Cookbook” by Juan Manuel Ferreyra. It is available as e-book and “dead tree edition”. The book is filled with dozens of easy to follow recipes (with a few glitches in them), covering creating graphics, working on photos and doing stuff for web design. There is not much background information in there, you have to be the right learning type to enjoy it. (I got a free e-book for review.)

To test the book I “cooked” the recipe for making a rubber stamp. It worked out quite well. On the way I found a filter that I had never seen before.

Finally I show how much the print dialogue in GIMP 2.7 has improved since 2.6. A lot of usability thoughts have gone in there.

The video filesize is too large – I am working on shrinking i further. But I wanted to get the show out.

Episode 158: Three kinds of Particles

Download the Video! (14:51 28.2 MB)
Download the torrent file!

[flattr /]There was a question left open in the last show: How to create a random pattern of particles that follow a gradient in density.

I got three answers. One from Benton – just use a brush with absurdly high jitter. Then I got the help that I asked for from Philippe and finally thought about a way myself. I started with Philippe’s tutorial for making a starfield.

And I recommend the Youtube channel of GimpTricks.

The TOC (by Kevin)

00:25 Welcome to GimpTricks ??
01:02 Welcome to Meet The Gimp
01:40 Benton’s solution to the random particles problem:
02:40 – Set Jitter on the paintbrush tool by typing
03:45 – Adjust the jitter to change the density
05:18 Philippe’s solution:
05:34 – Put a gradient on a quickmask
06:05 – Add noise to the gradient and fill the selection with black
06:47 – Use the threshold tool to adjust the density
07:17 Rolf’s solution:
07:33 – Fill a black layer with HSV Noise
08:48 – Add a new transparent layer in subtract mode
09:03 – Fill the subtraction layer with a gradient
09:50 – Use the threshold tool to control the density
10:45 – Bigger blobs needed
10:50 – Select the blobs using the colour selection tool and fill with blue
11:16 – Stroke the selection and Gaussian blur the blobs
12:45 – Use a picture instead of a gradient
14:51 The End

Sorry, not here up to now.

[flattr /]I am doing some homework for school this time. Getting a balloon up into the air and making air molecules visible. All with GIMP. πŸ˜‰

We have a new interactive white board at school. And I try to make a series of images of a balloon for a physics lesson. I am using layers, paths, selections and more – a lot of stuff for some simple drawings. Philippe could have done this better, I fear. πŸ˜‰

Calligraphy (mostly) in GIMP

Steve Czajka blogs about calligraphy in GIMP. Once a week he shows his newest work (like the one here) and writes a tutorial about what he has done. I have just skimmed this site – and I am impressed. The combination of manual skill with pen and paper and the processing with GIMP and Inkscape give really impressive results.

The image on the right has another important quality. Several elements in it come from different artists who have licensed their work under Creative Commons. By sharing their work they enable others to use it further and in new combinations.

Next week I’ll post another little bit here. It will be a challenge for you and you will need a tie. πŸ˜‰

Tutorial 001: Keeping Track of Time…

clockWe have something new here – written tutorials! Morten aka LuX is more into writing than making a video – and I (Rolf) love written tutorials and prefer them over video if they have enough images.

And now I give over to LuX, who will show you how to make a Grandfathers Clock from scratch:

This is something I’ve been working on the last month. I wanted to emulate a old longcase clock aka grandfather clock standing in our living room.

You can download the final XCF.

This tutorial isn’t difficult. I follow the KISS rule; Keep It Simple, Stupid!
Feel free to respond and create you own version maybe upload in user gallery in the forum.

Episode 105: Another Bowl of Soup?

Download the Video!
Download the Companion File! (if there is one…. otherwise 404….)

105Philippe was working on bank notes – but it turned out to be a too big task for the available time. The designers of these notes have one thing on top of their minds – make it difficult to copy.

With the money being on the back burner, Philippe made us a bowl of soup – absolutely low on calories and from scratch.

You’ll see how to get a textured plane into the shape of the soup, create reflections and steam and to control the light.

Episode 102: Ancient Wisdom Rusting Away

Download the Video!
Download the Companion File! (if there is one…. otherwise 404….)
102A metal sign has been sitting on a wooden wall for decades, rusting away in the weather.Nobody really cared.

But in reality this sign was made from scratch by Philippe, with a generous amout of bump mapping and applying plasma. Two things are to be thought about – making this three dimensional and getting the age effects right. Rust blooms and runs and so there are several ways to go to emulate it.

Every time I watch one of these shows I am stunned by the ease of making a three dimensional effect with some simple shadows.

Do you have any ideas for future “From Scratch” shows? Post them here in the comments or go to the forum! It’s not that we are running out of ideas really soon, but a little input from you would be very appreciated.
