Cutting module in LSystems

Cutting is now in the library. It is used to simulate shedding of plant parts, i.e. palm trees. The idea of shedding is the following: if cut symbol (module) is in the string, then all following symbols in current branch are skipped, i.e. R, StartBranch, F, Cut, F, L, EndBranch is transformed into R, StartBranch, […]

Viewer includes 2 examples – Tree (taken from L+C description) and Leaf. Some changes were done in LSystems to be able to render 2d: * Introduced Turtle namespace containing everything needed for turtle rendering, […]

Project source code is […]
