Light Painting Machine


Josh Sheldon created this mind-blowing video in which he 'paints' Blender objects into real-world scenes using a Blender controlled Arduino robot arm. The video also shows a making of and Josh shares technical details and the code that he used.

Josh writes:

I made this robot to make light painting animations.

Each of the animations I made took between 4 and 12 hours to shoot, one frame at a time. Each frame is 1-3 long exposure photographs of the machine performing the light painting.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. nice...
    but i don't like that the light traces shows aliases...
    is the light pulse-width-modulated?
    maybe you can smooth the pulses with a electrical low-pass-filter.
