Back when I was training in Dreamworks Animation to be an FX Artist, we got the task of writing a ray tracer from scratch and create your own interesting scene with existing assets in the internal library. I wanted to stand out and decided to focus on reflections and refractions to be the defining factor.
I want to share that output with you. Note this is a low resolution photograph of the output. This has received no post processing treatment whatsoever.
Following are some pictures from select places from unaccountable numbers of places Durga Pooja happens all over the city. I wasn’t home this time but thanks to internet we are always connected.
Other than that, I have been working on this drawing and I want to share it with you. Durga the invincible, the goddess of power:
This is possibly one of the simplest ray tracer, written not to technically achieve anything, but to understand the basic theory. This code is minimal, written in C, uses just the algorithms needed to trace, very less pointers usage, and no use of any external libraries other than ones which come packaged with Gcc by default. The code implements the following lighting models: ambient, diffuse, specular, hard shadows, reflections and one sided refractions. Please find the download link after a sample output, it is shared with the most relaxed license.
This was done for a one day workshop at BITS Pilani Hyderabad Campus few days ago (for their technical fest ATMOS). The challenge was to teach introduction to computer graphics and the basic theory of ray tracer, in one day, to a wide range of undergraduate students who may not be coming from a computer science background. I hope the students gained something and found it interesting.
