Rewrote MathB.in (http://mathb.in) from scratch in order to publish a cleaner implementation of this tool under the terms of BSD 2-Clause License. The previous implementation was a poorly designed one night hack.

It now supports LaTeX, Markdown and HTML. Visit http://github.com/susam/mathb to see the source code or report issues.

#math #latex #markdown #html #mathjax  
 
MathB.in ( http://mathb.in ) is now free and open source software ( http://github.com/susam/mathb ). MathB.in now supports Markdown along with LaTeX and HTML.

looks rather raw. More work needed to make it useful online.

I learnt just now that the word "meme" was coined by Richard Dawkins in his book 'The Selfish Gene'. Quoting from the book:

"We need a name for the new replicator, a noun that conveys the idea of a unit of cultural transmission, or a unit of imitation. 'Mimeme' comes from a suitable Greek root, but I want a monosyllable that sounds a bit like 'gene'. I hope my classicist friends will forgive me if I abbreviate mimeme to meme. If it is any consolation, it could alternatively be thought of as being related to 'memory', or to the French word même. It should be pronounced to rhyme with 'cream'."

The output of my first ray tracing experiment. Three light sources have been defined in this scene. The first one is to the left side of the scene. The second one is behind the camera shining directly infront of the dark blue sphere. The third one is behind the blue sphere between the white sphere and the yellow sphere behind it.

It uses orthographic projection to trace the rays. It means that the apparent size of the object does not change with the distance from the camera and there is no vanishing point in the image. I need to learn conic projection to achieve this. The concepts of diffusion, reflection and specularity have been used to do the ray tracing. Antialiasing is achieved by 4x supersampling.

The code was written in Java from scratch. Nothing outside the standard library has been used. Download the zip or the tarball from http://susam.in/files/code/ray-tracing/ to see the code.

Yes, I know about POV-Ray. I want to learn it. But first I want to do as much ray tracing I can by writing C++ programs.
