旋转LED阵列体显示系统的仿真平台构建

利用开放式图形库OpenGL，构建了一种为旋转发光二极管（LED）阵列三维体显示系统提供前期三维数据模拟和 图像预显示的软件仿真平台.该平台从3DS文件中获取体显示系统的三维物体信息，使用剪切算法转化为显示点集源数据 ，再经坐标变换得到LED面板的控制信号.用OpenGL中的一系列应用程序接口（application programming interface， API）函数在普通的平面显示器上仿真显示所得点集，同时将所得的控制信号生成二进制文件，用以驱动显示.对比不同 条件下的仿真结果可以确立最佳显示效果下实际系统的像素尺寸、分割扇区等硬件参数，并对图像质量进行预评价.

Establishment of simulation platform for volumetric display system based on rotating LED array

A software simulation platform utilizing open Graphics Library was established,which can provide three-dimensional data simulation and pre-display for volume display system based on a rotating light-emitting diode(LED) array panel.The information on three-dimensional object obtained from 3DS file was transformed into point-set for display using shear algorithm and turned into control signal of LED panel by coordinate conversion.Using the application programming interface(API) functions of OpenGL,the platform displays all point-set for simulation.The binary files including control signal were generated to drive LED panel through the platform.Simulation results under different parameters could specify some hardware parameters of the actual system with the optimal display effect,such as pixel dimension and sector numbers.The display images also could be pre-evaluated by the platform.
