The spherical primitive and perlin noise method to recreate realistic aggregate shapes

Abstract An algorithm to re-create virtual aggregates with realistic shapes is presented in this paper. The has been implemented the Unity 3D platform. idea realistically coarse and crushed that are normally used as a material for construction of roads. This method consists two major procedures: (i) combine spherical density function noise matrix based on Perlin obtain appropriate angularity and, (ii) deform until their minor ferret, aspect ratio thickness equivalent those wanted. efficiency tested by reproducing nine types from different sources. results obtained indicate proposed can be aggregates.
