[SVN + Mercurial] Mirroring and using an SVN repository with Mercurial

For trying some code changes in the Blender Game Engine I needed its code. It is accessible via SVN from https://svn.blender.org/svnroot/bf-blender/trunk/
With Git and Mercurial around I'm used to do local changes, commit them locally and maybe undo them if I made mistakes. With SVN this is not possible.

[BGE + GLSL] Py GL Rant

Let's do this.

Blender Game Engine.
It is nice.

But it also has its problems. Just like everything else.
This time I had a hard time doing some GLSL shaders. Not the normal ones.

[BGE+GLSL] Finding interest points

Interest Points

I learned a bit in a class called "Computer Vision".

One thing was "finding interest points". 

Basically when you have a picture and give it to your computer it doesn't know anything what to do with it. It's just plain boring data. Every point is as interesting as every other. On some images you might have the same feeling. On others you recognize things which gives it more value then just color. 

But what makes the difference?

How do you see something?
