Tungsteno is a project whose goal is to make mathematics accessible to everybody, completely free, based on open collaboration and the best pedagogical tools
Winning solutions of Kaggle's past competitions from grandmasters. If you are facing a data science problem, there is a good chance that you can find inspiration here!
This site contains many samples and prototypes that I have developed. All the code for the samples are available on bitbucket and people are free to do with it what they will. Ideally its best if you use the latest version of the Chrome browser, I tend to use the latest available APIs and features as I prototype and learn new subjects.
* 2D Prototypes
* 3D Fungi Prototypes
* SDF / Ray Marching Prototypes
* Three.js Prototypes
* 3D Shader Prototypes
* UI Web Components
* Misc
These are articles about the techniques I develop and lessons I learnt while toying or working with computer graphics. Most of it is self-taught and there's lots of reinventing the wheel (which I recommend) but also some innovative and new discoveries that often times are not documented anywhere else (and if any of this content becomes part of your paper or the center of your PhD thesis, I feel it'd be fair to mention this website).
