Black Carbon

A colleague was designing a booklet cover on the subject "Black carbon - India's Achilles Heel".. and we started discussing design ideas for it. i had a feeling that Black Carbon couldn't be just India's problem.. so i googled it, and happened upon this neat little info-graphic video(by about how its a worldwide issue. have a look

"Soot, also known as black carbon, is the second-leading cause of global warming after carbon dioxide, and it's totally preventable. We already have the technology to avoid producing it; it's just a matter of using it.

Global illumination in Sketchup

Finally found a 100% free renderer that i can use with Google Sketchup. It has materials and lighting presets, and gives excellent GI(global Illumination) out of the box.
"Global illumination is a general name for a group of algorithms used in 3D computer graphics that are meant to add more realistic lighting to 3D scenes. Such algorithms take into account not only the light which comes directly from a light source (direct illumination), but also subsequent cases in which light rays from the same source are reflected by other surfaces in the scene, whether reflective or non (indirect illumination).

Theoretically reflections, refractions, and shadows are all examples of global illumination, because when simulating them, one object affects the rendering of another object (as opposed to an object being affected only by a direct light). In practice, however, only the simulation of diffuse inter-reflection or caustics is called global illumination."
-wikipedia. click here for more on GI.

Anyway the renderer is called Kerkythea, and its been around for a while.. i just found it now :)

So now i'm taking my old sketchup models and rendering them with gi and more realistic materials
heres one of the first ones:
the dune buggy

buggy with default sketchup rendering

buggy rendered with GI using kerkythea's default settings

Basic Installation Instructions:
To start useing the Kerkythea with sketchup you need to get 3 things- the app, the plugin and the materials libraries.

For the app head over to the download page here , download and instal it.

For the plugin head over to the download page here, download and unzip them. Copy su2kt.rb and the su2kt folder into SketchupPlugins

you can start using Kerkythea now, with sketchup's own materials.. you'l get some nice renders with GI.

For the materials libraries head over to the download page here, after downloading, import them through the Kerkythea app. read the docs on the site for more instructions.

UPDATE Aug 2012
The official site has been down for a while. the team appears to be concentrating on the paid version called Thea Render. You can either purchase that here -


Get the older version  here(some material libraries also included). Its basically a backup of the version I used to do the renders you see above.
