This tutorial is meant as an exploration of some of the possibilities of sphere_sweeps in Pov-Ray. Below you find a summary of the various chapters.
Although I have tried to exclude mistakes from this tutorial, there remains much to be corrected or improved. Please tell me, in case you become aware of major issues...
The tutorial starts with a general introduction into sphere_sweeps. ()
First we use randomly generated positions to define the sphere_sweeps; we start with random coils. ()
This chapter demonstrates, how to cover a given object with sphere_sweeps. ()
A cushion plant is generated in a similar way using a variety of bowls made of random positions. ()
While the cushion plant was only a very rough approach towards branching, here is a more ordered way. ()
Then we introduce a method to generate "targeted" random sphere_sweeps. In addition we show a possibility to generate additional positions on such sphere_sweeps. ()
The method just mentioned forms the basis for our approach of constructing various branched structures... ()
The approach from the previous chapter is suitable to form intertwined sweeps. Here we show still another way to do so. ()
