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 😉

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….
