Ray casting-based method
Webgrowth by cellular automaton (CA) method and KGT growth model. Finite difference method[22] (FDM), finite volume method[23] (FVM), and finite element method[24] (FEM) are the three most common numerical methods used in the field of numerical simulation by casting. FDM is easy to implement, though it is only suitable for WebTo implement the algorithm we will add a contains method to the polygon class. To use the method you create a polygon and pass a point to the polygon's contains method. The …
