Short: Schema diagram from an existing sqlite database

I have a sqlite-database which is just a little too big to keep in my head,

so I was searching for a way to create a nice diagram from the existing schema.
I have been trying a lot of tools, none of them delivered.

Now, with version 14.14.01 of schemacrawler, I was able to produce a nice plot!

./schemacrawler.sh -server sqlite -database /home/shared/data/TobisGpsSequence/sequences_960_720_manual.db -infolevel=maximum -password= -command=schema -outputformat=png -outputfile=test.png

(Please ignore the crazy database layout, I am in the middle of a migration and you are looking at the work-in-progress that caused me to again look around for nice visualizing tools)

Groundtruth data for Computer Vision with Blender

In the last few days I took a look at blender again, and discovered that you can use Nodes to save individual render passes.
In the video below you can see the sequence of a car driving in a city scene and braking. The layers I rendered out for groundtruth data are the rendered image with the boundingbox of the car (top left), the emission layer ( shows the brakelights when they start to emit light, top right ), the optical flow (lower left), and the depth of each pixel in the world scene ( lower right).


Render-time was about 10h on a Nvidia GeForce GTX 680, tilesize 256×256, total image-size: 960×720.
