Left-click a third time dialog to complete the torusfractal construction.
NOTES, SPECIAL CASES OR EXCEPTIONS: The parameter '''Gen. Factor''' determines how many new next-level branches are generated at the end of each branch. '''Separation Angle''' sets the angle between each pair of branches at each node. The '''Prune Factor''' determines what percentage of branches are removed randomly at each node. With a default zero prune factor, all the branches are kept. The parameter '''Thickness''' represents the diameter of the main branch in the case of a cylinder key object. The parameter '''Thickness Factor''' determines the tapering of each cylindrical branch from its start point to the end point. A zero thickness factor means no branch tapering.
