What are orbit trap methods?
It has been assumed that the criterion used to color the point was only determined by the detection of the divergence of the function. Some specialists on fractal images have imagined more subtle methods. A fractal rendering method was developed by Paul Carlson in 1994 that was known as the 3D Stalks Method. That rendering method was the forerunner of several other fractal rendering methods developed by Carlson which have become known as “orbit trap” rendering methods, so named because during the iteration of a complex function the value of the function moves to different points in the complex plane, tracing out an “orbit”. An orbit trap is a closed area in the complex plane into which an orbiting point may fall. The principle is to test, for example, if the orbit of the point falls into a circle, an annulus, a square, et cetera. When this occurs, the point is considered to be “trapped” and the iteration loop is exited. The distance from the orbit point to the center of the area is the
