Reloading your code in Blender

Blender lets you script more or less everything. You can have your code inside Blender (and the .blend file) itself, but I prefer to store it outside the .blend file. This makes it easier to handle changes, and allows you to use any editor you want. The downside is that reloading your code becomes a bit of a hassle. This is a little snippet I wrote to reload my code in Blender with the click of a button.

Counting pixels in Blender

For my research, I'm using Blender to generate images. I wanted to know how visible a certain object is in the final render (i.e. how many pixels it occupies). For this there is the "object index" render pass (aka "IndexOB" in the compositor). I've been struggling with it, since it always outputs that the index is 0, even though there are multiple objects in the scene.

Well, with the help of mfoxdogg on the #blender IRC channel, we found a solution: You need to set the index by hand, for every object you're interested in. If you go to the object properties (in the properties explorer), in the section "Relations" there is a slider "Pass Index". This is set to 0 by default, and you can set it to any positive number you want. This is then reflected in the output of the "IndexOB" render pass.

Python-RSA version 3.1.4 released

Hacking, the analog way

It's been a while since I've been working on my RSA library, and in the last weeks I've released a few new minor versions. Here are the differences since my last blog post about it:

  • Fixed Python 3.x incompatibilities.

  • Dropped support for Python 2.5.

  • Added support for loading public keys from OpenSSL

  • rsa.pkcs1.verify() returns True when successful (thanks Tim Heckman)

  • First updated Distribute (thanks Jason R. Coombs), later replaced Distribute with Setuptools.

  • Fixed typo in pyrsa-verify help message

Comments via Disqus

My blog has been targeted by spammers for years. The last months spam has been on the rise, so I finally got fed up with it and replaced my home-grown comment system with Disqus. Old comments are still there, new ones will be using Disqus instead.

The Progression of Bingo Culture

This is the first time I've allowed a guest article on my blog. The photos are beautiful, and I think it fits well within this website. Note that the photo's aren't mine.

Michael Hess Captures the Vintage Beauty of Bingo of Decades Past

With so many subjects a photographer can cover when it comes to street photography, Michael Hess picked one particular topic that has had a very “colourful” yet underrated journey. The German street photographer has recently published a photography book that tackles the ever-present yet undermined bingo culture of UK.

“I played bingo one night in 2005, just out of curiosity about what went on inside the big old converted cinema near my house. I was instantly fascinated by the characters,” Hess shares the moment where he decided to pursue documenting such a decades-old culture in his official photography website. “The next time I visited, I took my camera. 4 years and more than 60 bingo halls later I was ready to make Bingo & Social Club.”
