Tutorial and Resources for Three.js
Three.js is one of a number of free WebGL libraries. First released in April 2010, it has become pretty popular, and includes a huge number of demos. I wanted to know more about its origins, so interviewed its creator, Ricardo Cabello, aka mr.doob, who lives in Spain. Interestingly, I am also largely motivated by Demoscenes when I was…
Tutorial of Ray Casting, Ray Tracing, Path Tracing and Ray Marching
Introduction As GPU power is becoming significantly better than CPU, ray casting / tracing, path tracing, and ray marching is widely used in 4k intros, demoscenes, and movies to create interactive 3D graphical scenes. Thanks to all the references listed in the end, I learnt so much about and I would like to share with the knowledge…
Bresenham’s Line Algorithm in C++
Bresenham’s line algorithm is an algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points. It is commonly used to draw lines on a computer screen, as it uses only integer addition, subtraction and bit shifting, all of…
