Recreating a paper alphabet in blender

When I saw Sabeena’s alphabet the first time, I instantly fell in love with the forms and colors. I was wondering if I could recreate the same feeling using Blender.

I tried first using only things I can find in Blender and ended up with techno-tourette.

So I decided to start up my old friend inkscape and scanned some curves off the original design of the letter U. I imported the curves back into Blender and extruded them. In order to get the feeling for the paper right, I added a solidify and a subsurf modifier to the whole thing, chose some colors and there you go.

I did not use a texture, but chose a subsurf modifier in addition to the BSDF.

Lesson learned: When you want to recreate complex paper foldings, it might be a good idea to use inkscape for the curves.

Unlimited area but no volume

I was always very fond of the Menger sponge. I built my level 4 sponge manually, not by using a recursive script. You can find a Python script for blender here. Here you will find some renders. I started with a simple lighting, did some reflection afterwards and finally changed the material to glass. Finally I changed the lighting to a two colored one and moved the camera inside. You can play yourself – take the blend file from here (nearly 2,5e6 triangles, 113 MB).

Concerning the headline: The Menger sponge is a strange thing. When the level goes towards infinite, the area does too but the volume goes towards 0.  Tip on the side: Do not try to imagine this sponge 😉

Glass of water

Made this one to remember that I should drink more water. What do you think?

Picture of the moon with the Nifty Fifty

There are a lot of pixels on that lovely Sony Nex-7. So many I could crop in the picture.

The Nex-7 has 24.3 MPixel on the sensor. The base file was 6000×4000 (24MP) and the final picture was a square crop 2580×2580 (6.7MP). That’s about 28% still left.

Proof of concept: Compositing video in Motion 5

When the weather is not that good outside, what do you do? I decided to play around with a snippet of video and try out some compositing with video.

What did I try? I wanted a piece of text to move with something in the background and vanish behind a piece of foreground.

So what did I learn?

  • Next time I use only stabilized imagery – the handheld footage is good enough for the poc (proof of concept).
  • I have to work on the 3d-text effect, it still has its problems.
  • I have to work on the synchronisation of the movement of background and foreground.

But enough talk – here is the video. I’ll be outside….

Number of the day: 2%

I love parcels. This does not mean that I do not understand all the packaging. I ordered the Upgrade to Adobe Lightroom 4, which is a great piece of software by the way.

As much it was fun to get the CD out of the box out of the box out of the box, there is the one question remaining: Why use so much air to package such a great product, where a nice small package with the serial number would be more than enough?

2% are not packaging air

Wallpaper: “Sunset on Vienna”

Facebook is a bitch.

I am one of those people who randomly post their pictures on facebook. And I am one of these people who want their pictures to be seen – I consider them art and not instances of reality. So if somebody asks for a wallpaper I cannot say no.

This might explain why the picture looks like it is. 

10mm have a very distinct look of its own and when you turn it into an HDR and apply the usual suspects: Contrast treatment, some glow, slight color shifting and some other lightroom thingies. Tataaaa – after approximately 100 minutes you get this.

Consider this a gift and use it as you like. Dimensions are FullHD (1920 x 1080) and license is creative commons. Have fun and consider sharing this post with your friends.

Or maybe you want to put this picture on your wall (german only)?
