基于3D技术的虚拟影视灯光仿真系统设计

Design of a VirtualMovie Lighting Simulation Platform Based on 3D Technique

针对影视灯光设计课程所需的专业实践性较强这一现状,此次研究构建了一种基于3D技术的虚拟影视灯光仿真系统,以更好地促进广播电视编导专业学生的能力培养。针对传统3D技术缺乏实时建模这一缺点,对其引入了粒子群算法,以提升系统的适应性和容错性。实验结果显示,所提方法在IPSO迭代40次左右的时候就体现出了较好的收敛效果和搜索能力;系统所渲染出的灯光效果图接近于真实演出效果。所提系统的虚拟模拟教学实验效果能够令学生满意,因此,具有较好的应用前景。

In response to the current situation of strong professional practicality required for film and television lighting design courses,this study has constructed a virtual movie lighting simulation platform based on 3D technique to better promote the ability cultivation of students majoring in radio and television directing.In response to the lack of real-time modeling,PSO algorithm has been introduced to enhance the adaptability and fault tolerance of the system.The experimental results show that the proposed method exhibits good convergence and search ability after approximately 40 IPSO iterations;The lighting effect image rendered by the system is close to the real performance effect.The virtual simulation teaching experiment effect of the proposed system is more satisfactory to students,so it has good application prospects.
