When using path tracing for rendering, the rays only produce a single ray per bounce. The rays do not follow a defined line per bounce (to a light, for example), but rather shoot off in a random direction. eagle eye sunglasses as seen on tv

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.

WebDescription. Casts a ray against Colliders in the Scene. A raycast is conceptually like a laser beam that is fired from a point in space along a particular direction. Any object making contact with the beam can be detected and reported. This function returns the number of contacts found and places those contacts in the results array.
