The code is for gnuplot and describes the relationship of light, reflected light (EM) and time in a complex system illustrated in the image below. The result is that there is certainly no Big Bong or Dark Master in "this" universe and Higgs does not have a son named bo. Strangely if you play the Queen of the Holy Dark card with Maxwell's equations you win Planck's constant and all the Physky acolytes walk the Planck, so tired of light. Doubtful if Dodgson would see the light in this looking glass.

The image below is from my camera and it has focus and I merged two images that focus the front and back, and I wonder why the heck would anybody want to take a picture where parts are out of focus, if it can easily be fixed by focusing based on distance and merging?

Assimp library is very nice for models and it is a good example of C++ code, but OpenGL is a mine field that is littered with GLSL ESL VGA X EXT .... and what a tangled web it is.
