# smallpt
## About
The Rosetta smallpt project: the same path tracer (modifications of Kevin Baeson's [99 line C++ path tracer](http://www.kevinbeason.com/smallpt/)) written in multiple languages.
**Note**: I deliberately chose for the same software design for [all programming languages](https://github.com/matt77hias/smallpt) out of clarity and performance reasons (this can conflict with the nature of declarative/functional programming languages).
## Features
**Current languages**:
* [C](https://github.com/matt77hias/c-smallpt)
* single threaded
* multi threaded (OpenMP)
* [C++](https://github.com/matt77hias/cpp-smallpt)
* single threaded
* multi threaded (Windows Threads)
* multi threaded (OpenMP)
* [C#](https://github.com/matt77hias/cs-smallpt)
* single threaded
* multi threaded
* [CoffeeScript](https://github.com/matt77hias/coffee-smallpt)
* [CUDA](https://github.com/matt77hias/cu-smallpt)
* [Erlang](https://github.com/matt77hias/erl-smallpt)
* [GLSL](https://www.shadertoy.com/view/MlcczX)
* [Haskell](https://github.com/matt77hias/hs-smallpt)
* [Java](https://github.com/matt77hias/java-smallpt)
* [JavaScript](https://github.com/matt77hias/js-smallpt)
* [J#](https://github.com/matt77hias/jsl-smallpt)
* [Prolog](https://github.com/matt77hias/pl-smallpt)
* Python 2
* [Python](https://github.com/matt77hias/py-smallpt)
* [Python + NumPy](https://github.com/matt77hias/numpy-smallpt)
* Python 3

* [Python + NumPy](https://github.com/matt77hias/numpy-smallpt)
* [Python + Taichi](https://github.com/burhanuddin6/accelerated_small_pt/tree/rand_solved)
* [Racket](https://github.com/matt77hias/rkt-smallpt)
* [TypeScript](https://github.com/matt77hias/ts-smallpt)
## Performance comparison
In order to give a very rough performance comparison, the wall clock time is measured of a single run to generate an image of resolution 1024x768 using 64spp. All single process - single threads experiments output the current progression to standard output. All multi process - multi threaded experiments do not output the current progression to standard output (this can change in the future).
**System**:
* OS: Windows 8.1 Pro 64 Bit
* CPU: Intel i7-4770K @ 3,50 GHz (TB @ 3,9 GHz) with 8GB DDR3 @ 1600 MHz
* GPU: NVIDIA GeForce GTX 970 with 4 GB GDDR5
**Note**: the random number generators used, differ between the languages and their implementations. It makes no sense to use the same random number generator in all implementations (i.e. C++ vs CUDA) and would introduce a huge burden to explicitly pass the state in languages such as Prolog.
