WebPixel perfect circles. 1. About the Bresenham algorithm. Bresenham is a quite common algorithm I actually discovered only a few months ago. And it proved to be incredibly useful for many purposes. This algorithm is basically used to draw a line between 2 points in a grid based space (ie. pixels). The result is a pixel perfect line, which is cool. WebMar 11, 2014 · Raycasting is the process of drawing a line from some point to measure the distance to the nearest solid. It has a huge number of uses, with beams and lasers being perhaps the most common. However raycasting is also used to measure angle relative to a solid, testing which solid is the closest, etc. Here is my optimized raycasting function.
