Nice I used to do ray-tracing with POV back in the 80s....Had to write specular shading components for it.
LOL I have a Master's in Compiler Construction and Computer Graphics. So marrying low level graphics and higher level control was my fortay....

What one can do with Blender and Sketchup is something we could have been doing back in the 80s had we had the processing power, memory and bandwidth!

Now it's bloatware...LOL
