checkout my rendering experiments using Raspberry Pi

The first thing I do once I buy a new computer is to put it to test to see how it performs when it comes to rendering complex 3d scene. Being a technical artist, its our job to innovate the most efficient workflow to get the best out of the available resources. So what If a 3d rendering task is thrown at the Raspberry Pi?
I decided to go with Aqsis, a 3D rendering solution adhering to RenderMan standard. Why Aqsis? Because its Open Source. So its just a matter of few hours to get Aqsis built for your distro running on Raspberry Pi (Raspbian in my case). It took approximately 4 hours for me to build Aqsis from source, including the time taken to build libTiff, one of the package dependencies for Aqsis. The rest of the dependent packages were readily available for Raspbian and it took only a few minutes to get all of them installed.
I used one of the example scenes that comes with Aqsis installation to test the same. Cranked up the resolution of the output image to 1920×1080 with the pixel samples set to the default value of 4×4. From the logs, it showed that it took less than 3 hours to render the frame including the time taken for shadow map generation at 512×512 resolution. Shown below is the rendered image converted to PNG (from native TIF format)
