中文摘要：
具有复杂形状的真实矿物颗粒仿真已成为影响分选理论研究一个重要瓶颈。为实现对矿物颗粒的真实模拟,提出了一种随机仿射分形仿真的计算机图形学算法,利用VC和OpenGL编程实现,并已应用于煤炭颗粒的振动筛分过程的虚拟实验仿真系统中。应用表明该算法能真实地模拟实际颗粒,增加了仿真的真实感和准确性,并具有较高的运行效率。
英文摘要：
The complex shade mineral particles simulation had become an important bottleneck of separation theory research. A random fractal-based simulation algorithm for mineral particles is put forward and implemented by VC and OpenGL programming. The algorithm had been used in virtual experiment system of coal particles vibration screening process, and the results show that the algorithm can simulate actual particles factually. The realistic and accuracy of virtual simulation system are increased by the algorithm which also has a high efficiency.
